What is the smallest possible integer for which 18% of that integer is greater than 3.5 ?
A14
B 16
C 18
D 20
E 22

Answers

Answer 1

Answer:

D 20

Step-by-step explanation:

Let's call the integer we're looking for "x". We know that 18% of x is greater than 3.5, so we can write the inequality:

0.18x > 3.5

To solve for x, we can divide both sides by 0.18:

x > 3.5 ÷ 0.18

x > 19.44

We want the smallest possible integer that satisfies this inequality, which is 20. So the answer is D) 20.

Last weekend, Mrs. Nelson earned $132 selling rings. She earned $6 for each ring she sold.

How many rings did she sell?

Answers

Hi!

Let's think about this really quick.

Each ring is $6. She made $132.
In order to find the solution, we need to divide the total from the original price of the ring, making the equation: 132÷6.
132÷6= 22.

So, she sold 22 rings. To verify that answer, we'll multiply 6 to 22.
6x22=132.

22 Is your answer.

Answers

We can be 95% confident that the mean duration of imprisonment, p, of all political prisoners with chronic PTSD is somewhere between 19.4 months and 46.1 months.

Therefore the answer is A.

A confidence interval is a range of values that is likely to contain the true population parameter (in this case, the mean duration of imprisonment for political prisoners with chronic PTSD). The confidence level (in this case, 95%) indicates the percentage of times that the interval will contain the true population parameter in repeated sampling.

Option A correctly interprets the confidence interval by stating that we can be 95% confident that the true mean duration of imprisonment for political prisoners with chronic PTSD falls between 19.4 months and 46.1 months. This means that if we were to take many random samples of political prisoners with chronic PTSD and calculate the mean duration of imprisonment for each sample, 95% of the resulting confidence intervals would contain the true population mean.

Option B is incorrect because a confidence interval does not give the probability of the population parameter being in a particular range. It only gives the probability that the interval will contain the true population parameter if the sampling and estimation process is repeated many times.

Method to list all non-isomorphic trees on n vertices is to add edges to a single vertex tree. Using A, B, C, D, E, we list 5 non-isomorphic trees on 6 vertices.

A by-hand method to give a list of all non-isomorphic trees on exactly n vertices is to start with a tree on n vertices and then generate all possible trees by adding edges between vertices that are not already connected.

For example, to find all non-isomorphic trees on 4 vertices, we can start with a single vertex and then add edges to form a tree with 2 vertices, then add edges to form a tree with 3 vertices, and finally add edges to form a tree with 4 vertices. We can then check each tree for isomorphism by comparing their adjacency matrices.

Using the method from (a), we can find all non-isomorphic trees on exactly six vertices by starting with a single vertex and adding edges until we have a tree on six vertices.

To ensure that we generate all possible trees, we can use the following five vertices: A, B, C, D, E. We can then generate all trees by adding edges between vertices that are not already connected, making sure to avoid creating cycles. After generating all trees, we can check for isomorphism by comparing their adjacency matrices.

Answers

If Andres Michael bought a new boat. He took out a loan for $24,420 at 3.5% interest for 2 years. Andres Michael owes $18806.6 at maturity.

How to find the amount?

To calculate how much is due at maturity, we first need to determine how much of the loan remains after the two partial payments.

To do this, we can use the formula for simple interest:

I = P * r * t

Where:

I = Interest

P = Principal (original loan amount)

r = Annual interest rate

t = Time (in years)

The interest for the first two months can be calculated as:

I1 = P * r * t1

= 24420 * 0.035 * (2/12)

= 142.45

So after the first two months, the amount owing on the loan is:

P1 = P + I1 - 4330

= 24420 +142.45 - 4330

= 20,232.45

The interest for the next four months can be calculated as:

I2 = P1 * r * t2

= 20,232.45 * 0.035 * (4/12)

= 236.05

So after six months, the amount owing on the loan is:

P2 = P1 + I2 - 2600

=  20,232.45 + 236.05- 2600

= 17868.50

Now we can calculate the interest for the remaining 18 months:

I3 = P2 * r * t3

=  17868.50* 0.035 * (18/12)

= 938.10

So the total amount owing at maturity (after 2 years) is:

Total amount owing = P2 + I3

=  17868.50 + 938.10

= 18806.6

Therefore, Andres Michael owes $18806.6 at maturity.

What is Probability?

A probability is a numerical representation of the likelihood or chance that a specific occurrence will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

According to question:

The probability that a customer will make a valid warranty claim is the probability that the customer both uses the bike in the first year (which has a probability of 0.75) and discovers a defect (which has a probability of 0.10).

Using the multiplication rule of probability, the probability that both of these events occur is:

0.75 x 0.10 = 0.075

Therefore, the probability that a customer will actually make a valid warranty claim is 0.075.

During a manufacturing process, a metal part in a machine is exposed to varying temperature conditions. The manufacturer of the machine recommends that the temperature of the machine part remain below 135°F. The temperature T in degrees Fahrenheit x minutes after the machine is put into operation is modeled by T=-0.005x^2+0.45x+125. Will the temperature of the part ever reach or exceed 135°F? Use the discriminant of a quadratic equation to decide.​

Answers

Using the discriminant of the quadratic equation, the temperature will part after 50 minutes

Will the temperature of the part ever reach or exceed 135°F?

The temperature of the machine part is given by the equation:

T = -0.005x^2 + 0.45x + 125

We need to find out if the temperature will ever reach or exceed 135°F, which means we need to check if there exists a value of x for which T = 135.

Substituting T = 135 in the above equation, we get:

135 = -0.005x^2 + 0.45x + 125

Simplifying the equation, we get:

0.005x^2 - 0.45x + 10 = 0

This is a quadratic equation of the form ax^2 + bx + c = 0, where a = 0.005, b = -0.45, and c = 10.

The discriminant of this quadratic equation is given by:

D = b^2 - 4ac

= (-0.45)^2 - 4(0.005)(10)

= 0.2025 - 0.2

= 0.0025

Since the discriminant is positive, the quadratic equation has two real roots. Therefore, the temperature of the machine part will cross 135°F at some point during the operation.

We can also find the roots of the quadratic equation using the formula:

[tex]x = (-b \± \sqrt(D)) / 2a[/tex]

Substituting the values of a, b, and D, we get:

[tex]x = (0.45 \± \sqrt(0.0025)) / 2(0.005)\\= (0.45 \± 0.05) / 0.01[/tex]

Taking the positive value, we get:

x = 50

Therefore, the temperature of the machine part will cross 135°F after 50 minutes of operation.

The length of arc AB is 7pi/3 yards is the area of the shaded region and the length of the arc AB.

what is circle?

A circle is a geometric shape that consists of all points in a plane that are equidistant from a fixed point called the center.

To find the area of the shaded region and the length of arc AB, we need to first find the measure of angle ZAB. Let's call this angle x.

Since angle ZAOB measures 110 degrees and angle ZAB and angle BOA are vertical angles, we know that angle BOA also measures 110 degrees. Therefore, angle ZAB + angle BOA = 180 degrees.

So, we can write:

x + 110 = 180

Solving for x, we get:

x = 70

Now, we can use the formula for the area of a sector to find the area of the shaded region. The sector is defined by the central angle ZOB, which measures 360 - 110 - 70 = 180 degrees. So, we have:

Area of shaded region = (180/360) * pi * 6^2 = 18pi

Therefore, the area of the shaded region is 18pi square yards.

To find the length of arc AB, we can use the formula:

Length of arc AB = (x/360) * 2 * pi * 6

Plugging in x = 70, we get:

Length of arc AB = (70/360) * 2 * pi * 6 = 7pi/3

Therefore, the length of arc AB is 7pi/3 yards.

Answer:

[-3, 7].

Step-by-step explanation:

do i need to explain all that?

Answer:

The inequality can be rewritten as x-7 ≤ 50, which we can solve by adding 7 to both sides to get x ≤ 57.

Step-by-step explanation:

It seems like there are multiple questions combined in this one prompt. I will break them down and provide solutions for each one.

Solution for O x≤-3 or 2 Ox<-3 or 2 O-3≤x≤2 or x > 7:

To find the solution for this inequality, we need to solve each part separately and then combine the solutions using the union (OR) operation.

a) x ≤ -3: This part is already solved for x. The solution is x ≤ -3.

b) 2x < -3: We divide both sides by 2 to isolate x and get x < -3/2.

c) 2 ≤ x ≤ -3: This is not possible as there is no number that is both greater than or equal to 2 and less than or equal to -3.

d) x > 7: This part is already solved for x. The solution is x > 7.

The solution to the entire inequality is the union of these solutions: x ≤ -3 OR x < -3/2 OR x > 7.

Solution for x²+x-6 < 0

To solve this quadratic inequality, we can factor it as (x-2)(x+3) < 0 and use the sign chart method.

We create a sign chart for the expression (x-2)(x+3) and test the sign of the expression in each interval

  -3         2

  ---|-------|---

    -         +

(x-2) - 0 + +

(x+3) - - - 0 +

-------------

- + - 0 +

The sign chart tells us that the expression is negative when x is between -3 and 2. Therefore, the solution to the inequality is -3 < x < 2.

Solution for x-7 ≤ 50₂

It seems like the expression "50₂" is intended to represent the number 50 in base 2 (binary). To convert this number to base 10 (decimal), we can write 50₂ as

50₂ = 12^5 + 12^4 + 02^3 + 02^2 + 12^1 + 02^0 = 32 + 16 + 2 = 50

Therefore, the inequality can be rewritten as x-7 ≤ 50, which we can solve by adding 7 to both sides to get x ≤ 57.

1 On a map of scale 1:100 000, the distance between Tower Bridge
and Hammersmith Bridge is 12.3 cm.
What is the actual distance in km?

Answers

To calculate the actual distance in km, we need to use the scale factor of 1:100 000. This means that 1 cm on the map is equivalent to 100 000 cm in real life.

Therefore, 12.3 cm on the map is equivalent to 12.3 x 100 000 cm in real life.

Now, 1 km is equivalent to 100 000 cm.

Therefore, 12.3 x 100 000 cm is equivalent to 1.23 km.

Hence, the actual distance in km is 1.23 km.

A dietician is planning a snack package of fruit and nuts. Each ounce of fruit will supply zero units of​ protein, 3 units of​ carbohydrates, and 2 unit of​ fat, and will contain 40 calories.

Every package must provide at least 4 units of​ protein, at least 11 units of​ carbohydrates, and no more than 16 units of fat. Find the number of ounces of fruit and number of ounces of nuts that will meet the requirement with the least number of calories. What is the least number of​ calories?

Let x be the ounces of fruit and y be the ounces of nuts. What is the objective function that must by​ minimized?

z = __x + __y

The dietician should use ___ ounce(s) of fruit and ___ ​ounce(s) of nuts. These amounts will have a total of ___calories.
(Type your answer in whole numbers)

Answers

The objective function that must be minimized is:

z = 40x + 50y

subject to the constraints:

0x + 4y ≥ 4 (protein constraint)

3x + 2y ≥ 11 (carbohydrate constraint)

2x + 4y ≤ 16 (fat constraint)

We want to find the number of ounces of fruit (x) and nuts (y) that will meet the requirement with the least number of calories.

Solving the system of inequalities, we get:

x = 2 ounces

y = 2 ounces

Therefore, the dietician should use 2 ounces of fruit and 2 ounces of nuts. These amounts will have a total of 180 calories (402 + 502).

Answer:

Step-by-step explanation:

Let's assume we need x ounces of fruit and y ounces of nuts to meet the requirements with the least number of calories. Then, the problem can be expressed as an optimization problem:

Minimize: 40x + 50y (since we want to minimize the number of calories) Subject to:

0x + 4y ≥ 4 (we need at least 4 units of protein)3x + 2y ≥ 11 (we need at least 11 units of carbohydrates)2x + 4y ≤ 16 (we cannot have more than 16 units of fat)

To solve this problem, we can use the simplex method. First, we convert the problem to standard form by introducing slack variables:

Minimize: 40x + 50y Subject to:

0x + 4y + s1 = 43x + 2y + s2 = 112x + 4y + s3 = 16

Now we can create the initial simplex tableau:

xys1s2s3RHSs1041004s23201011s32400116z-40-500000

We want to find the minimum value of z, so we need to choose the variable with the most negative coefficient in the bottom row as the entering variable. In this case, that is y. We then choose the variable with the smallest non-negative ratio between the right-hand side and the coefficient of the entering variable in its row as the leaving variable. In this case, that is s3, since 16/4 = 4 is the smallest non-negative ratio.

We then perform the pivot operation to eliminate the coefficient of y in the other rows:

     x  y  s1s2s3RHSs1001-214y3/2101/2-1/24s2-1001-1/25z-100025-15200

We repeat this process until all the coefficients in the bottom row are non-negative. The final tableau is:

prove that the absolute value of x-y is greather than the absolute value of x minus the absolute value of y

Answers

Using the properties of  absolute value function, proved that |x - y| > |x| - |y| is true for all x and y.

To prove that |x - y| > |x| - |y|, we can consider two cases

Case 1

x >= 0 and y >= 0

In this case, |x - y| = x - y and |x| - |y| = x - y. So we have

|x - y| = x - y

| x | - | y | = x - y

Substituting these expressions into the original inequality, we get:

x - y > x - y

This inequality is true for all x and y where x >= 0 and y >= 0, since the difference between x and y is always greater than or equal to zero.

Case 2

x < 0 and y < 0

In this case, |x - y| = -(x - y) and |x| - |y| = -x + y. So we have:

|x - y| = -(x - y)

| x | - | y | = -x + y

Substituting these expressions into the original inequality, we get

-(x - y) > -x + y

Simplifying both sides, we get

y - x > -x + y

Adding x to both sides, we get

y > 0

This inequality is true for all x and y where x < 0 and y < 0, since both x and y are negative and the difference between x and y is always less than or equal to zero.

The missing side is 30.

What is a triangle?

Three line segments that cross at three non-collinear locations to form a triangle constitute a triangle in geometry. The triangle's three line segments are referred to as its sides, and its three points of intersection as its vertices.

A triangle is a three-sided polygon formed by three line segments intersecting at three non-collinear points, and it can be classified based on the length of its sides and the measure of its angles.

Given figure, there are two lines ate parallel, that's why two triangles are similar triangle.

What is coordinates?

Coordinates are a set of values that locate the position of a point in space. In mathematics, coordinates are used to represent the position of points on a plane or in space, using a set of numerical values that correspond to the distance along each axis from an origin point. In two-dimensional Cartesian coordinate systems, for example, a point is represented by two numbers (x, y) that indicate its position relative to the x and y axes. In three-dimensional Cartesian coordinate systems, a point is represented by three numbers (x, y, z) that indicate its position relative to the x, y, and z axes.

Here,

The average rate of change between the points (3,9) and (5,15) is the slope of the line passing through those two points. We can use the slope formula:

slope = (y2 - y1) / (x2 - x1)

where (x1, y1) = (3,9) and (x2, y2) = (5,15).

slope = (15 - 9) / (5 - 3)

= 6 / 2

= 3

A triangle has an area of 144 square feet. The height is 24 feet. What is the length of the base (in feet)?

Answers

We can use the formula for the area of a triangle to solve for the length of the base:

Area = (1/2) x base x height

We know that the area is 144 square feet and the height is 24 feet, so we can substitute those values into the formula:

144 = (1/2) x base x 24

To solve for the length of the base, we can first simplify the right-hand side of the equation:

144 = 12 x base

Dividing both sides by 12, we get:

12 = base

Therefore, the length of the base of the triangle is 12 feet.
