Question:
A running club keeps track of the number of hours each person has trained for a race and the length of time it takes the person to run the race. A scatter plot is graphed with the x-axis indicating the number of hours a runner has trained and the y-axis indicating the time, in minutes, it took to run the race. The equation y = 60 - 0.5x is used as the line of best fit of the data. What does the slope of the equation represent?

options:

a
Runners will decrease their race time by 2 minutes for every 1 hour they have trained.
b
Runners will increase their race time by 2 minutes for every 1 hour they have trained.
c
Runners will increase their race time by 1 minute for every 2 hours they have trained.
d
Runners will decrease their race time by 1 minute for every 2 hours they have traine

Answers

The solution is, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

What is scatter plot?

A scatter plot is a type of plot or mathematical diagram using Cartesian coordinates to display values for typically two variables for a set of data. If the points are coded, one additional variable can be displayed.

Here, we have,

We are given the scatter plot which shows the distance he has run and the time it took for each run.

We are asked to determine a good prediction of how long it will take Tom to run the 6 mile race?

One way to predict the time is by drawing a line that best fits the given data.

As you can see, from the line of best fit, the time corresponding to the 6 miles is around 60 minutes.

Therefore, 60 minutes is a good prediction of how long it will take Tom to run the 6 mile race.

Answers

Answer:

6. x = 16

7. n = -11

Step-by-step explanation:

6. -7(x-6)=-70

= -7x + 42 = - 70

= - 7x = - 70 - 42

= -7x = -112

= -7x/-7 = -112-/7

= x = 16.

15
1/15
2/3

Thanks!!!!

Answers

Answer:

Is 1/15

Explicación:

Ya que dividiendo 1/3 para 5 das 1/15.

Since dividing 1/3 for 5 gives 1/15.

1/15 because you would divide this right well nope you do kcf aka keep change flip and 5/1 would now be 1/5 and you changed division to multiplication so it looks like this 1/3x1/5

2/3 a - 1/6 = 1/3

answer this math question asap pls

Answers

Answer:

a=3/4

Step-by-step explanation:

1. Get 2/3a by itself.

•Turn 1/3 to 2/6 by multiplying 1/3 by 2/2.

•Because you only add and subtract like denominators

This will make it look like:

2/3a - 1/6 = 2/6

Then, add 1/6 to both sides to get 2/3a by itself.

It'll look like this:

2/3a = 3/6

2. Get a by itself.

•Multiply the reciprocal (opposite) of 2/3 to get a alone.

This will look like:

(3/2) • 2/3a = (3/2) • 3/6

a = 18/24

3. Simplify.

Find the largest number that can simplify the equation.

For example, 18 ÷ 3 = 6, and 24 ÷ 3 = 8.

But the largest number you can divide both sides by is 6.

18 ÷ 6 = 3 and 24 ÷ 6 = 4.

3/4.

the answer is a= 3/4

Ahmad’s goal is to exercise for a mean of 45 minutes per day for one week. For the first six days of the week, he exercised 35, 40, 37, 42, 45, and 50 minutes. What is the number of minutes Ahmad must exercise on the 7th day to meet his goal for the week?

Answers

Answer:

41.5

Step-by-step explanation:

To find the mean, your supposed to add all the numbers you have and divide by how many numbers there are. In this question your numbers are 35, 40,37,42,45, and 50.

If you add them all up you get 249. Your next step is to divide by how many numbers there are. Since there are 6, your equation will now be 249 divided by 6. Your answer is now 41.5

So on the 7th day Ahmad exercised for 41.5 minutes. If you need to round then maybe 41 minutes.

Answer:

41.5

Step-by-step explanation:

On the 7th day Ahmad exercised for 41.5 minutes and if you want to put it simply its 41 minutes.

Step-by-step explanation:

Cubic centimeters used in final wood sculpture = volume of rectangular prism minus volume of triangular prism

To find the volume of a rectangular prism simply multiply the width by the length by the height

The rectangular prism has a given width of 20cm, a given height of 30cm and a given length of 20cm

So volume of rectangular prism = 20 * 20 * 30 = 12,000

Now let's find the volume of the triangular prism she cut out.

To find the volume of a triangular prism we can use this formula

V = bh/2 * l

Where b = base length, h = height of base and l = length of prism

The triangular prism has a given base length of 12cm a given height of 12cm and a given length of 30cm ( we can tell by looking at the image the length of the triangular prism is the same as the height of the rectangular prism.)

We then plug in these dimensions into the formula

V = (12*12)/2 * 30

12 x 12 = 144

144/2 = 72

72 * 30 = 2160

Finally we subtract the volumes

12,000 - 2160 = 9840

We can conclude that the volume of the final sculpture is 9840 cubic centimeters
