PLEASE HELP! YOU WILL GET 90 POINTS!
Part 1
You will need to measure five different people. Record your measurements on a piece of paper. Using a tape measure or
ruler, measure the length (in inches) or a person's left foot and then measure the length (in inches) of that same person's
forearm (between the wrist and elbow). Refer to the diagrams below. You will have two measurements for each person
(An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and
measure the outline once they move of the paper)
To measure the forearm measure inside the arm, between the wrist and the elbow.
(my measurements are here)
foot - 8.5 in
forearm - 8.5 in
foot - 9.5 in
forearm - 9.5 in
foot - 8 in
forearm - 9.5 in
foot - 9.5
forearm - 9.5 in
(I only have four)
Part 2
Organize your data and find the rate of change.
A. Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output.
B. Select two sets of points and find the rate of change for your data.
C. Describe your results. If you had to express this relation as a verbal statement, how would you describe it?
Part 3
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 foot) = 0.860 • (length of forearm) + 3.302
If you let y = length of foot and x = length of 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.
You will submit the details from all three parts. Submit your measurements, the table, and description that you created in Parts 1 and 2. Submit your answers to the questions from Part 3.
I know that was a lot but I really need help.

(c) compare the results of parts (a) and (b). in general, how do you think the mode, median, and mean are affected when each data value in a set is multiplied by the same constant? multiplying each data value by the same constant c results in the mode, median, and mean increasing by a factor of c. multiplying each data value by the same constant c results in the mode, median, and mean remaining the same. multiplying each data value by the same constant c results in the mode, median, and mean decreasing by a factor of c. there is no distinct pattern when each data value is multiplied by the same constant. (d) suppose you have information about average heights of a random sample of airline passengers. the mode is 65 inches, the median is 72 inches, and the mean is 65 inches. to convert the data into centimeters, multiply each data value by 2.54. what are the values of the mode, median, and mean in centimeters? (enter your answers to two decimal places.) mode cm median cm mean cm in this problem, we explore the effect on the mean, median, and mode of multiplying each data value by the same number. consider the following data set 7, 7, 8, 11, 15. (a) compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = (b) multiply 3 to each of the data values. compute the mode, median, and mean. (enter your answers to one (1) decimal places.) mean value = median = mode = --
