Therefore, the 2-liter bottle is the more cost-effective option as it has a lower cost per milliliter.
What are millimeters?Millimeters (mm) is a unit of length in the metric system. It is a subunit of a meter, with one meter being equal to 1000 millimeters. Millimeters are commonly used to measure small distances such as the thickness of paper, the width of a fingernail, or the diameter of a small object. The abbreviation for millimeters is "mm".
by the question.
To evaluate which option is the most cost-effective, we need to compare the cost per milliliter of each option.
Calculate the price per liter: To compare the cost of the two options, you'll need to calculate the price per liter of each. You can do this by dividing the price of the bottle by its volume in liters. For example, if the 2-liter bottle costs $4, the price per liter would be $2 ($4/2 liters). If the 750ml bottle costs $2.50, the price per liter would be $3.33 ($2.50/0.75 liters).
Compare the price per liter: Once you have the price per liter for each option, you can compare them. In this example, the 2-liter bottle is cheaper at $2 per liter compared to the $3.33 per liter for the 750ml bottle.
Consider the convenience: While the 2-liter bottle may be cheaper, you should also consider if it's more convenient for you. If you won't be able to use all the 2-liters before it goes bad, or if it's difficult to carry around, then multiple 750ml bottles may be a better option for you despite the higher cost per liter.
For the 750ml bottle:
[tex]Cost per milliliter = R28 /750ml[/tex]
[tex]Cost per milliliter = R0.0373/ml[/tex]
For the 2-liter bottle:
[tex]Cost per milliliter = R63 / 2000ml[/tex]
[tex]Cost per milliliter = R0.0315/ml[/tex]

With the information given, can you prove
that this quadrilateral is a parallelogram?
A. Yes
B. No
AB = DC
We cannot prove that the quadrilateral is a parallelogram with only the given information that AB = DC.
What is quadrilateral and parallelogram ?
A quadrilateral is a four-sided polygon, which means it is a closed shape with four straight sides. Some examples of quadrilaterals include rectangles, squares, trapezoids, and rhombuses.
A parallelogram is a special type of quadrilateral where both pairs of opposite sides are parallel. This means that the opposite sides never intersect, and they have the same slope. Additionally, the opposite sides of a parallelogram are congruent (i.e., have the same length), and the opposite angles are also congruent. Some examples of parallelograms include rectangles, squares, and rhombuses.
To prove that a quadrilateral is a parallelogram, we need to show that both pairs of opposite sides are parallel. Knowing that AB = DC only gives us information about the lengths of the sides, but it doesn't tell us anything about their orientation or whether they are parallel.
We would need additional information, such as the measures of angles or the lengths of other sides, to determine whether the quadrilateral is a parallelogram.

In baseball, each time a player attempts to hit the ball, it is recorded. The ratio of hits compared to total attempts is their batting average. Each player on the team wants to have the highest batting average to help their team the most. For the season so far, Jana has hit the ball 8 times out of 10 attempts. Tasha has hit the ball 9 times out of 12 attempts. Which player has a ratio that means they have a better batting average?
Tasha, because she has the lowest ratio since 0.75 < 0.8
Tasha, because she has the highest ratio since 48 over 60 is greater than 45 over 60
Jana, because she has the lowest ratio since 0.75 < 0.8
Jana, because she has the highest ratio since 48 over 60 is greater than 45 over 60
Jana, because she has the highest ratio since 8/10 is greater than 9/12.
What is ratio?A ratio is a comparison of two numbers or quantities expressed in relation to each other. It represents the relative size or magnitude of one quantity with respect to another. Ratios are typically written as a fraction, with the first number being the numerator and the second number being the denominator, and can also be expressed as a decimal or percentage.
What is batting average?Batting average is a statistical measure used in baseball to evaluate a player's performance at the plate. It is calculated as the ratio of a player's total number of hits to their total number of at-bats (the number of times they attempt to hit the ball).
In the given question,
A higher batting average indicates a better performance, since it means the player is successfully hitting the ball more often.
In this case, we are given the number of hits and attempts for two players, Jana and Tasha. To compare their batting averages, we need to calculate the ratio of their hits to their attempts.
Jana has hit the ball 8 times out of 10 attempts, so her batting average is 8/10 = 0.8.
Tasha has hit the ball 9 times out of 12 attempts, so her batting average is 9/12 = 0.75.
To determine which player has the better batting average, we compare their ratios. Since 0.8 is greater than 0.75, Jana has the higher ratio and therefore the better batting average.
So, the answer is Jana, because she has the highest ratio (8/10 = 0.8), which means she has the better batting average compared to Tasha (9/12 = 0.75).

The midpoint of the diameter is (4, 1)
This is the center of the circle
=====================================================
Explanation:
Add up the x coordinates and divide in half
(-1+9)/2 = 8/2 = 4
The x coordinate of the midpoint is x = 4
Repeat for the y coordinates
(4 + (-2))/2 = (4-2)/2 = 2/2 = 1
The y coordinate of the midpoint is y = 1
The midpoint is located at (x,y) = (4,1)
The midpoint of any diameter is the center of the circle. This is because all diameters go through the center.
The distance from the center to either endpoint represents the radius of the circle (aka half the diameter).

Five cars start out on a cross-country race. The probability that a car breaks down and drops out of the race is 0.2. Cars break down independently of each other.
(a) What is the probability that exactly two cars finish the race?
(b) What is the probability that at most two cars finish the race?
(c) What is the probability that at least three cars finish the race?
(a) The probability that exactly two cars finish the race is 0.0512.
(b) The probability that at most two cars finish the race is 0.05792.
(c) The probability that at least three cars finish the race is 0.94208.
(a) To determine the probability that exactly two cars finish the race, we have to use binomial distribution. In this case, we have n = 5 trials, and p = 0.8 is the probability that a car finishes the race (1 - 0.2). Using the binomial distribution formula:
P(X = k) = (nCk)(p^k)(1 - p)^(n - k)
Where X is the number of cars that finish the race, we get:
P(X = 2) = (5C2)(0.8²)(0.2)³= (10)(0.64)(0.008)= 0.0512
Therefore, the probability that exactly two cars finish the race is 0.0512.
(b) To determine the probability that at most two cars finish the race, we have to calculate the probabilities of 0, 1, and 2 cars finishing the race and add them up.
P(X ≤ 2) = P(X = 0) + P(X = 1) + P(X = 2)= (5C0)(0.8⁰)(0.2)⁵ + (5C1)(0.8¹)(0.2)⁴ + (5C2)(0.8²)(0.2)³= 0.00032 + 0.0064 + 0.0512= 0.05792
Therefore, the probability that at most two cars finish the race is 0.05792.
(c) To determine the probability that at least three cars finish the race, we can calculate the probability of 0, 1, and 2 cars finishing the race and subtract it from 1, which gives us the probability of at least three cars finishing the race.
P(X ≥ 3) = 1 - [P(X = 0) + P(X = 1) + P(X = 2)]= 1 - (0.00032 + 0.0064 + 0.0512)= 0.94208
Therefore, the probability that at least three cars finish the race is 0.94208.

use the trapezoidal rule and simpson's rule to approximate the value of the definite integral for the given value of n. round your answer to four decimal places and compare the results with the exact value of the definite integral. 4 x x2 1 0 dx, n
The Trapezoidal rule and Simpson's rule are two methods used to approximate the value of a definite integral. The Trapezoidal rule approximates the integral by dividing the region between the lower and upper limits of the integral into n trapezoids, each with a width h. The approximate value of the integral is then calculated as the sum of the areas of the trapezoids. The Simpson's rule is similar, except the region is divided into n/2 trapezoids and then the integral is approximated using the weighted sum of the area of the trapezoids.
For the given integral 4 x x2 1 0 dx, with n = 200, the Trapezoidal rule and Simpson's rule approximate the integral to be 7.4528 and 7.4485 respectively, rounded to four decimal places. The exact value of the integral is 7.4527. The difference between the exact and approximate values is very small, thus indicating that both the Trapezoidal rule and Simpson's rule are accurate approximations.

The data in Exercise 1 were taken from the following functions. Compute the actual errors in Exercise 1, and find error bounds using the error formulas.
a. f ( x ) = sin x b. f (x) = ex − 2x2 + 3x – 1
The actual errors for Exercise 1 can be computed by subtracting the calculated values from the true values of the functions. For example, the actual error for sin(1.1) can be found by subtracting sin(1.1) = 0.8912 from the calculated value of 0.8890. The actual error in this case is 0.0022.
Error bounds for these functions can be found using the error formulas. For the function f(x) = sin x, the error bound can be found using the formula |E| <= M|x-a|, where M is the maximum value of the first derivative of the function, and a is the value of x at which the error is computed. In this case, M = 1 and a = 1.1, so the error bound is |E| <= 1 * |1.1 - 1.1| = 0.
For the function f(x) = ex - 2x2 + 3x - 1, the error bound can be found using the formula |E| <= M|x-a|2, where M is the maximum value of the second derivative of the function, and a is the value of x at which the error is computed. In this case, M = e and a = 1.1, so the error bound is |E| <= e * |1.1 - 1.1|2 = 0.

Goods with a cost price of R200 are sold at a mark-up of 100%. The selling price is:
If the cost price of the goods is R200 and they are sold at a mark-up of 100%, then the selling price is equal to the cost price plus the mark-up, or:
Selling price = Cost price + Mark-up
Mark-up = 100% x Cost price
= 100% x R200
= R200
So the mark-up is R200.
Selling price = Cost price + Mark-up
= R200 + R200
= R400
Therefore, the selling price of the goods is R400.

Answer:
3. 79.9 mm²
4. 6.4 in
5. 177.5 mi²
6. 60.3°
Step-by-step explanation:
Given various quadrilaterals and their dimensions, you want to find missing dimensions.
Trig relationsIn all cases, one or more area formulas and trig relations are involved. The trig relations are summarized by the mnemonic SOH CAH TOA. The relevant relation for these problems is ...
Tan = Opposite/Adjacent
It is also useful to know that 1/tan(x) = tan(90°-x).
Area formulasThe formula for the area of a trapezoid is ...
A = 1/2(b1 +b2)h
The relevant formula here for the area of a parallelogram is ...
A = bs·sin(α) . . . . . where α is the angle between sides of length b and s
3. Parallelogram areaUsing the area formula above, we find the area to be ...
A = (21 mm)(9 mm)·sin(155°) ≈ 79.9 mm²
The area is about 79.9 square mm.
4. Trapezoid base 2The given figure shows two unknowns. We can write equations for these using the area formula and using a trig relation.
If we draw a vertical line through the vertex of the marked angle, the base of the triangle to the right of it is (b2-4). The acute angle at the top of that right triangle is (121°-90°) = 31°. The tangent relation tells us ...
tan(31°) = (b2 -4)/h ⇒ h = (b2 -4)/tan(31°)
Using the area formula we have ...
A = 1/2(b2 +4)h
and substituting for A and h, we get ...
20.8 = 1/2(b2 +4)(b2 -4)/tan(31°)
2·tan(31°)·20.8 = (b2 +4)(b2 -4) = (b2)² -16 . . . . . multiply by 2tan(31°)
(b2)² = 2·tan(31°)·20.8 +16 . . . . . . . add 16
b2 = √(2·tan(31°)·20.8 +16) ≈ 6.4 . . . . . . take the square root
Base 2 of the trapezoid is about 6.4 inches.
5. Trapezoid areaTo find the area, we need to know the height of the trapezoid. To find the height we can solve a triangle problem.
If we draw a diagonal line parallel to the right side through the left end of the top base, we divide the figure into a triangle on the left and a parallelogram on the right. The triangle has a base width of 10 mi, and base angles of 60° and 75°.
Drawing a vertical line through the top vertex of this triangle divides it into two right triangles of height h. The top angle is divided into two angles, one being 90°-60° = 30°, and the other being 90°-75° = 15°. The bases of these right triangles are now ...
h·tan(30°)h·tan(15°)and their sum is 10 mi.
The height h can now be found to be ...
h·tan(30°) +h·tan(15°) = 10
h = 10/(tan(30°) +tan(15°))
Back to our formula for the area of the trapezoid, we find it to be ...
A = 1/2(b1 +b2)h = 1/2(20 +10)(10/(tan(30°) +tan(15°)) ≈ 177.5
The area of the trapezoid is about 177.5 square miles.
6. Base angleThe final formula we used for problem 5 can be used for problem 6 by changing the dimensions appropriately.
A = 1/2(b1 +b2)(b1 -b2)/(tan(90-x) +tan(90-x))
112 = 1/2(20+12)(20-12)/(2·tan(90-x)) = (20² -12²)·tan(x)/4
tan(x) = 4·112/(20² -12²)
x = arctan(4·112/(20² -12²)) = arctan(7/4) ≈ 60.3°
Angle x° in the trapezoid is about 60.3°.

There is no set "step by step" for solving problems like these. In general, you work from what you know toward what you don't know. You make use of area and trig relations as required to create equations you can solve for the missing values. There are generally a number of ways you can go at these.

The second attachment shows a graphing calculator solution to problem 5, where we let y = area, and x = the portion of the bottom base that is to the left of the top base. Area/15 represents the height of the trapezoid. This solution also gives an area of 177.5 square miles.
three cards are drawn with replacement from a standard deck of 52 cards. find the the probability that the first card will be a club, the second card will be a red card, and the third card will be the six of hearts.
The probability of drawing a club, a red card, and the six of hearts in that order from a standard deck of 52 cards is [tex]1/13,552.[/tex]
This is because the probability of drawing a club is 1/4, and the probability of drawing a red card is 1/2, and the probability of drawing the six of hearts is 1/52.
Since the cards are drawn with replacement, the total probability is the product of the individual probabilities, which is equal to [tex]1/4 * 1/2 * 1/52 = 1/13,552[/tex].
It is important to note that if the cards were not drawn with replacement, then the probability of drawing the three cards would be slightly different. The total probability would be equal to [tex]1/4 * 1/2 * 1/51 = 1/12,600.[/tex]

The statistical test that a researcher could use to test the null hypothesis that the mean body temperature of residents in a nursing home is 98.6°F is a one-sample t-test.
What is a statistical test?A statistical test is a method that enables the comparison of the collected data with the assumed distribution of the data. A statistical test aids in determining if the outcomes of the experiment or research are caused by the treatment or if they are due to the random variation in the data.
A null hypothesis is a type of hypothesis that predicts the absence of a relationship between variables or groups. The null hypothesis claims that no difference exists between two variables or groups, and that any observed differences are due to chance.
Alternative hypotheses are used to reject null hypotheses, as they predict the presence of a relationship between variables or groups.
The significance level, which is the probability of committing a Type I error, is often used to set the null hypothesis. The statistical test that a researcher could use to test the null hypothesis that the mean body temperature of residents in a nursing home is 98.6°F is a one-sample t-test.

A square is inscribed in a right triangle with leg lengths 6 and 8 so that they have a common right angle. FInd the square's side length.
Answer:
10 units
Step-by-step explanation:
Here, legs = base and perpendiculars.
So, Clearly given Base = 6 units Perpendicular = 8 cm
Square's Side = Hypotenuse.
By Pythagoras theorem,
H² = B²+P²
H ² = 6²+8²
H² = 36+64 = (10)²
H = 10 units.

Student A can solve 75% of problems, student B can solve 70%. What is the probability that A or B can solve a problem chosen at random?
The probability that student A or B can solve a problem chosen at random is 0.95.
Probability is calculated by dividing the number of favourable outcomes by the number of possible outcomes.
Random: An event is referred to as random when it is not possible to predict it with certainty. The probability that either student A or B will be able to solve a problem chosen at random can be calculated as follows:
P(A or B) = P(A) + P(B) - P(A and B) where: P(A) = probability of A solving a problem = 0.75, P(B) = probability of B solving a problem = 0.7, P(A and B) = probability of both A and B solving a problem. Since A and B are independent, the probability of both solving the problem is:
P(A and B) = P(A) x P(B) = 0.75 x 0.7 = 0.525
Now, using the above formula: P(A or B) = P(A) + P(B) - P(A and B) = 0.75 + 0.7 - 0.525 = 0.925
Therefore, the probability that student A or B can solve a problem chosen at random is 0.95 (or 95%).

according to a census, 3.3% of all births in a country are twins. if there are 2,500 births in one month, calculate the probability that more than 90 births in one month would result in twins. use a ti-83, ti-83 plus, or ti-84 calculator to find the probability. round your answer to four decimal places. provide your answer below:
According to a census, 3.3% of all births in a country are twins. In a month, there are 2,500 births. The census reports that 3.3% of all births result in twins, and the probability of having more than 90 twins in a month is "0.4351."
We will solve this problem using the binomial distribution formula, which is as follows:P (X > 90) = 1 - P (X ≤ 90)where P represents the probability, X represents the number of twins born in a month, and X is a binomial random variable with a sample size of n = 2,500 and a probability of success (having twins) of p = 0.033. Using the TI-83 calculator, TI-83 Plus, or TI-84 calculator, the following steps can be followed:
Press the "2nd" button followed by the "VARS" button (DISTR) to access the distribution menu. Scroll down and select "binomcdf (" from the list of options (use the arrow keys to navigate). The binomcdf ( menu will appear on the screen. The first number in the parentheses is the number of trials, n, and the second number is the probability of success, p. We want to find the probability of having more than 90 twins, so we need to use the "compliment" option. Therefore, we will subtract the probability of having 90 twins or less from 1 (using the "1 -" key). Type in "binomcdf (2500,0.033,90)" and press the "ENTER" button on your calculator.
This will give you the probability of having 90 twins or fewer in a month. Subtract this value from 1 to obtain the probability of having more than 90 twins in a month, which is the answer to our question. P(X>90) = 1 - binomcdf (2500,0.033,90)P(X>90) = 1 - 0.5649P(X>90) = 0.4351Therefore, the probability of having more than 90 twins in a month is 0.4351.
