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
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.

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?
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.

The perimeter of a square is 100 feet. What is the length of one of its sides? Explain your work.
Answer:
25
Step-by-step explanation:
to find the perimeter you add up all the sides and since it's a square and squares have all four equal sides
you just divide 100/4=25
4 sides of a square. Each side of a square is equal. You said the perimeter is 100. So if we put it in an equation, lets say S = Side. 4s=100. Now we just divide. s=25
Each side is 25

A bullet of mass m1 = 0.020 kg is fired with initial speed v1 into a block of mass m2 = 0.500 kg that is initially at rest. The bullet becomes embedded in the block and the pair slide along to the right a distance d= 0.35 m over a rough surface with uk = 0.25. the spring (with k = 450 N/m) is compressed by a distance of x = 0.075 m. work backwards and determine the initial velocity of the bullet.
6. −7(x−6)=−70
7. Solve for n *(4 Points) 9+n=−2
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.
7. 9 + n= - 2
= n= -2 - 9
= n = -11

2/3 a - 1/6 = 1/3
answer this math question asap pls
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.
