Robyn recorded her distance (d) for different lengths of time (t) she ran. Which equation represents the relationship between t and d?

Answers

Answer 1

The relationship between the distance (d) covered by Robyn for different lengths of time (t) can be represented by the equation d = ct, where c is a constant. Robyn ran for different lengths of time and measured the distance she covered each time.

To represent the relationship between d and t, we need to consider how d and t are related. This can be done by finding a pattern in the data. Robyn may have collected data for different values of t and d. We can represent this data in a table like this Time (t) (in minutes) Distance (d) (in meters)1 The table shows that as the value of t increases, the value of d also increases.

We can represent this relationship between d and t using a linear equation of the form y = mx + b, where y is the dependent variable (in this case, d), x is the independent variable (in this case, t), m is the slope of the line, and b is the y-intercept. To find the equation that represents the relationship between d and t, we need to find the values of m and b. We can do this by using two points from the table. For example, we can use the points (10, 50) and (20, 100).The slope (m) of the line passing through these points can be found using the slope formula: m = (y2 - y1)/(x2 - x1) = (100 - 50)/(20 - 10) = 5.The y-intercept (b) can be found by substituting the value of m and one of the points into the equation y = mx + b. Using the point (10, 50), we get:50 = 5(10) + b Solving for b, we get b = 0. Therefore, the equation that represents the relationship between d and t is d = mt + b = 5t + 0 = 5t. The equation that represents the relationship between t and d is d = ct, where c is a constant.

Answers

By using double grouping, the expression can be factored as (x + 7)(x - 6).

To factor the expression x^2 + x - 42, an x-method chart is used to determine the factors. The completed chart shows 1 at the bottom of x, -42 at the top of x, 7 on the left side, and -6 on the right side.

The x-method chart is a helpful tool for factoring quadratic expressions. The completed chart provides us with the necessary information to factor the expression x^2 + x - 42. The product of -42 at the top of x and 1 at the bottom of x tells us that the factors of -42 are -6 and 7.

To factor the expression, we can use double grouping. We group the terms x and 7 together, as well as the terms x and -6 together. This gives us x(x + 7) - 6(x + 7). Notice that both groups have a common factor of (x + 7). We can factor out this common factor to obtain (x + 7)(x - 6).

To verify the factors, we can use the distributive property to multiply the factors back together. When we multiply (x + 7)(x - 6), we get x^2 + x - 6x - 42. Simplifying further, we have x^2 - 5x - 42, which is equivalent to the original expression x^2 + x - 42. Therefore, (x + 7)(x - 6) is the correct factored form of the given expression.

Wyatt drew a map of Barton Springs Pool. On the map, 1/3inch represents 15 yards. The actual length of the pool is about 333 yards. What is the length in inches of the pool on the map?

Answers

7.4 inches is the length in inches of the pool on the map.

To find the length of the pool on the map in inches, we can set up a proportion using the given scale:

1/3 inch represents 15 yards

Let's denote the length of the pool on the map as "x" inches.

Using the proportion, we have:

(1/3) / 15 = x / 333

To solve for x, we can cross-multiply:

15 * x = (1/3) * 333

15x = 333/3

15x = 111

Dividing both sides by 15, we find:

x = 111 / 15

x ≈ 7.4

Therefore, the length of the pool on the map is approximately 7.4 inches.

A certain standardized test's math scores have a bell-shaped distribution with a mean of 525 and a standard deviation of 114. Complete parts (a) through (c) (a) What percentage of standardized test scores is between 411 and 639? % (Round to one decimal place as needed.) (b) What percentage of standardized test scores is less than 411 or greater than 639? v % (Round to one decimal place as needed) (c) What percentage of standardized test scores is greater than 753? 1% (Round to one decimal place as needed)​

Answers

(a) To find the percentage of standardized test scores between 411 and 639, we need to calculate the z-scores corresponding to these values and then use the standard normal distribution table.

For 411:

z = (411 - 525) / 114 = -1.00

For 639:

z = (639 - 525) / 114 = 1.00

Using the standard normal distribution table, we can find that the area to the left of -1.00 is 0.1587 and the area to the left of 1.00 is 0.8413. Therefore, the percentage of scores between 411 and 639 is:

Percentage = (0.8413 - 0.1587) * 100 = 68.3%

(b) To find the percentage of scores less than 411 or greater than 639, we can subtract the percentage calculated in part (a) from 100%:

Percentage = 100% - 68.3% = 31.7%

(c) To find the percentage of scores greater than 753, we need to calculate the z-score for 753:

z = (753 - 525) / 114 = 2.00

Using the standard normal distribution table, we can find that the area to the left of 2.00 is 0.9772. Therefore, the percentage of scores greater than 753 is:

Percentage = (1 - 0.9772) * 100 = 2.8%

Davidson is on a cross country motorcycle trip and has just arrived at the foothills of the Rockies. He plans to take 1 hour longer on the 245 km trip up the east side than on the 225 km trip down the west side. To do this he will average 20 km/h faster on the downhill side. How long will the trip through the Rockies take?

Answers

Davidson has just arrived at the foothills of the Rockies and is on a cross-country motorcycle trip. He intends to take an hour longer on the east side of the 245 km trip than on the west side of the 225 km trip. On the downhill side, he intends to average 20 km/h more to achieve this. The trip through the Rockies will take approximately 17.375 hours.

Let the speed of the motorcycle on the west side of the trip be x km/h.

So, the time required to complete the 225 km trip will be:

Time for the west side of the trip = 225/x

Let the speed of the motorcycle on the east side of the trip be x + 20 km/h.

So, the time required to complete the 245 km trip will be:

Time for the east side of the trip = 245 / (x + 20)

We know that the time Davidson takes on the east side of the trip will be an hour longer than on the west side. Therefore, we can form the following equation:

245/(x + 20) = 225/x + 1

Multiplying both sides by x(x + 20),

we get:245x = 225(x + 20) + x(x + 20)

Simplifying the equation:20x = 400x = 20 km/h

Time taken on the west side of the trip is 225/20 = 11.25 hours

Time taken on the east side of the trip is 245/40 = 6.125 hours

So the total time for the trip through the Rockies is 11.25 + 6.125 = 17.375 hours, or about 17 hours and 22.5 minutes (rounded to the nearest minute).

Therefore, the trip through the Rockies will take approximately 17.375 hours.

Ed invested $500 at 3% annual interest compounded quarterly. Write an equation and find how much money he will have in 7 years.

Answers

We can use the formula for compound interest: after 7 years, Ed will have approximately $617.

To determine how much money Ed will have after 7 years of investing $500 at an annual interest rate of 3% compounded quarterly, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where:

A = the final amount

P = the principal amount (initial investment)

r = the annual interest rate (expressed as a decimal)

n = the number of times interest is compounded per year

t = the number of years

In this case, P = $500, r = 3% (or 0.03), n = 4 (quarterly compounding), and t = 7. Plugging these values into the formula, we can calculate the final amount:

A = 500(1 + 0.03/4)^(4*7)

Simplifying the equation, we get:

A = 500(1.0075)^(28)

Calculating the expression within the parentheses, we find:

A = 500(1.234)

Finally, we can compute the final amount:

A = $617

The standard deviation of a point estimator is the _____.

Answers

The standard deviation of a point estimator is a measure of the variability or precision of the estimator.

In statistics, a point estimator is a function that uses sample data to estimate an unknown parameter of a population. The standard deviation of a point estimator quantifies how much the estimates from different samples are expected to deviate from the true value of the parameter. A smaller standard deviation indicates a more precise estimator, as the estimates are expected to be closer to the true value. Conversely, a larger standard deviation suggests a less precise estimator with estimates that are more spread out. By calculating the standard deviation of a point estimator, we can assess its reliability and determine the level of confidence we can have in the estimated parameter value.

a) What is their taxable income?

b) What is their marginal tax rate?

c) What is their effective tax rate? Round to the nearest hundredth of a percent.

Answers

For Alex and Tory, their taxable income is $150,000, their marginal tax rate is 22%, and their effective tax rate is 4.57%.

a) To calculate their taxable income, we need to subtract their deductions and exemptions from their gross income. However, the given information does not provide the specific deductions and exemptions for Alex and Tory. Therefore, we cannot determine their taxable income.
b) The marginal tax rate refers to the tax rate applied to the last dollar of taxable income. Without knowing their taxable income, we cannot calculate their exact marginal tax rate.
c) The effective tax rate is the total tax paid as a percentage of the gross income. To find their effective tax rate, we divide the total taxes due by their gross income and multiply by 100. For Alex and Tory, their total taxes due are not provided, so we cannot calculate their exact effective tax rate.

Anne fires a toy rocket into the air from the top of a barn. The height of the rocket above the ground in feet, after t seconds is given by the function h(t)=−5t2+20t−15 . After completing the trajectory, Anne finds that the maximum height the toy rocket reached in the air is represented by the expression −5(t−−)2+5. What is the missing piece of the expression.

Answers

The missing piece in the expression −5(t−−)2+5 is 2.hence, the correct expression for the maximum height reached by the toy rocket is −5(t−2)2+5.

to find the missing piece in the expression −5(t−−)2+5, representing the maximum height of the rocket, we can compare it with the given function h(t) = −5t² + 20t − 15.

the given function h(t) represents the height of the rocket above the ground at any given time t. to find the maximum height, we can determine the vertex of the quadratic equation −5t² + 20t − 15.

the vertex of a quadratic equation in the form ax² + bx + c can be found using the formula: x = -b/2a.

for our equation −5t² + 20t − 15, we can find the vertex as follows:

t = -20 / (2 * -5)t = -20 / -10

Answers

If Adam’s credit card has an APR of 14. 63%, his balance at the end of June would be c. $627. 27.

How to determine the daily balance

To determine the balance at the end of the billing cycle, we have to calculate the sum of the daily balance and also point out the number of days in the billing cycle.

Beginning balance = 626.25

We add purchases and subtract payments as follows:

626.25 +  37. 41  + 44. 50 -  65. 50  +  24. 89 - 104. 77 - 23. 60  + 15. 00 + 51. 85 = 606.03

Average daily balance = sum of daily balance/number of days in the billing cycle

Average daily balance = 626.25 + (9 * 37.41) + (2 * 44.50) + (21 * 65. 50) + (13 * 24.89) + (4 * 104.77) + (16 * 23.60) + (4 * 15) + (4 * 51.85)/90

626.25 + 336.69 + 89 + 1375.5 + 323.57 + 419.08 + 377.6 + 60 + 207.4

3815.09/90

= $42.389

Periodic rate = APR divided by 4 (for quarterly periods)

= 0.1463/4

= 0.0365

Periodic rate * average daily balance + beginning balance

= 0.0365 * 42.389 + 626.25

= 1.5472 + 626.25

≈ 627

A bee flies at 12 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 12 minutes, and then flies directly back to the hive at 8 feet per second. It is away from the hive for a total of 17 minutes.


a. What equation can you use to find the distance of the flowerbed from the hive?


b. How far is the flowerbed from the hive?

Answers

Given that a bee flies at 12 feet per second directly to a flowerbed from its hive. The bee stays at the flowerbed for 12 minutes, and then flies directly back to the hive at 8 feet per second.

It is away from the hive for a total of 17 minutes. We are to determine the equation to find the distance of the flowerbed from the hive and the distance of the flowerbed from the hive.(a) We know that distance = speed × time. Let us use the variable d to represent the distance of the flowerbed from the hive. Using the formula distance = speed × time, the distance the bee traveled from the hive to the flowerbed is:d = 12 × 60The bee stays at the flowerbed for 12 minutes, which is equivalent to 12 × 60 seconds,

so the distance the bee traveled from the flowerbed to the hive is: d = 8 × 60To find the total distance traveled, we need to add the distance from the hive to the flowerbed to the distance from the flowerbed to the hive. The total distance is d = (12 × 60) + (8 × 60) Combining like terms gives us: d = 20 × 60Therefore, the equation that can be used to find the distance of the flowerbed from the hive is: d = 1200. (b) The distance of the flowerbed from the hive is 1200 feet since the equation used to find the distance is: d = 1200.

The area of the figure is given by 34cm²

What is the area of a triangle?

The figure is made up of  triangle and a square.

The area of the figure is given by area of the square + area of the triangle

The area of a triangle is the total space occupied by the three sides of a triangle in a 2-dimensional plane. The basic formula for the area of a triangle is equal to half the product of its base and height, i.e., A = 1/2 b h. This formula is applicable to all types of triangles, whether it is a scalene triangle, an isosceles triangle, or an equilateral triangle

area of triangle = 1/2bh

Area of triangle = 1/2*10*6

Area = 30 com²

But the area of the square is S²

Where s = side

Area of square = 2*2 = 4cm²

A proposed mechanism for ozone destruction in the late spring over northern latitudes in the lower stratosphere begins with the photochemical decomposition of ClONO_2 to Cl and NO_3, followed by photochemical decomposition of the later to NO and O_2. Deduce a catalytic ozone destruction cycle, requiring no atomic oxygen, that incorporates these reactions. What is the overall reaction?

Answers

A catalytic ozone destruction cycle requires no atomic oxygen and it incorporates the photochemical decomposition of ClONO₂ to Cl and NO₃, and photochemical decomposition of the later to NO and O₂. The overall reaction is NO + O₃ → NO₂ + O₂

In the lower stratosphere, a proposed mechanism for ozone destruction in the late spring over northern latitudes begins with the photochemical decomposition of ClONO₂ to Cl and NO₃. This reaction is catalyzed by sunlight in the lower stratosphere. The photodissociation of NO₃ is the next step in the cycle, and it results in the production of NO and O₂.

The NO then reacts with O₃ in the following reaction: NO + O₃ → NO₂ + O₂The NO₂ that is produced then reacts with atomic oxygen to form NO₃, and the cycle starts again with the photodissociation of ClONO₂. The NO that is produced during the reaction between NO₂ and O₃ can also react with atomic oxygen to form NO₂, which can then go on to form NO₃.However, the catalytic cycle that has been proposed requires no atomic oxygen to be present. The NO that is produced during the reaction between NO₂ and O₃ reacts with more O₃ to form NO₃ and O₂: NO + O₃ → NO₂ + O₂NO₂ + O₃ → NO₃ + O₂The NO₃ that is produced in this reaction can then go on to react with more O₃, starting the cycle over again. Thus, the overall reaction for the catalytic ozone destruction cycle is:NO + O₃ → NO₂ + O₂NO₂ + O₃ → NO₃ + O₂NO₃ + O₃ → NO + 2O₂The cycle continues as long as the necessary reactants are available.

What is the dividend when the divisor is 6 and the quotient is 90 with a remainder of 4?

Answers

The dividend is the result of multiplying the divisor and quotient and adding the remainder. In this case, the divisor is 6, the quotient is 90, and the remainder is 4.

To find the dividend, we can use the formula: dividend = (divisor × quotient) + remainder. Substituting the given values, we have: dividend = (6 × 90) + 4. Simplifying this expression, we get: dividend = 540 + 4. Adding 540 and 4, we find that the dividend is 544.

The dividend represents the total quantity or value that is being divided. In this context, if we divide the dividend (544) by the divisor (6), we would obtain the quotient of 90 with a remainder of 4. So, when dividing 544 by 6, we can expect the quotient to be 90 and a remainder of 4.
