Compare rates of change.A. The equation below can be used to find the length of a foot or forearm when you know one or the other. (length of the foot) = 0.860 • (length of the forearm) + 3.302 If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302. Using this equation, how long would the foot of a person be if his forearm was 17 inches long? B. What is the rate of change of the equation from Part A? Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different? C. Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.

I can't draw a line but the figure drawn based on the given description is a RIGHT TRIANGLE.

Richmond to Easton is the short leg.
Dayton to Easton is the hypotenuse.
Richmond to Dayton is the long leg.

We are looking for the measure of the long leg. We will use the Pythagorean theorem.

a² + b² = c²
a² + 16² = 32²
a² + 256 = 1,024
a² = 1,025 - 256
a² = 768 mi²
a = √768 mi²
a = 27.71 mi   This is the distance of Dayton from Richmond

R ---------E

RE = 16mi
DE = 32 mi

DR^2 = DE^2 - RE^2 = (32mi)^2 - (16mi)^2 = 768 mi^2

DR = √(768 mi^2) = 27.7 mi

sarita recorded the distances she ran for 5 days:5 miles,4mi,5.5mi,4.5,5.5 what is the mean distance sarita ran

Answers

The mean distance Sarita ran for 5 days = 4.9 miles.

What do we mean by mean of data?

The mean of given data is the summation of all variables divided by the number of variables.

Mean = ∑X/n

where X represents variables and n represents the number of variables.

How do we calculate the mean of the given data?

We have got data for 5 days. The variables are 5 miles, 4 miles, 5.5 miles, 4.5 miles, and 5.5 miles. Number of variables = 5.

∑X = 5 + 4 + 5.5 + 4.5 + 5.5 = 24.5 miles.

n = 5.

∴ Mean = ∑X/n = 24.5/5 = 4.9 miles.

The mean distance Sarita ran for 5 days = 4.9 miles.

#SPJ2
How you find the mean is to add all the numbers in that group together, and divide that number by the number of numbers there were in that group.
For this problem, here is what you do:

5+4+5.5+4.5+5.5 = 5.0+4.0+5.5+4.5+5.5 = 24.5

Then:

24.5 / 5 = 4.9

So...:
your final answer is 4.9 miles as the mean.

I hope this helps you.
