Question

medal and fan

Answer 1

Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
Write the equation of the line of best fit using the slope-intercept formula y=mx+b. Show all your work, including the points used to determine the slope and how the equation was determined.
What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
Test the residuals of two other points to determine how well the line of best fit models the data.
Use the line of best fit to help you to describe the data correlation.
Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arm span is 66 inches?
According to your line of best fit, what is the arm span of a 74-inch-tall person?

Answer 2

@Hope210 can you help please?

Answer 3

@Conqueror @wwhitlock
one of them should be able to help you :) I'm not that good at math :(

Answer 4

Wow. This looks like math. I read the problem, it reads like math. I have only a clue to what's being asked. But I don't think it's a good clue.

Answer 5

I completed the graph and the data record. i just need to answer the questions about it

Answer 8

@Mehek14 can you help please?

Answer 9

I'm guessing this is a qualified helper question like the other one?

Answer 10

@perl can you help please?

Answer 11

@hockeybeast10 sorry lol i dont even understand what i read

Answer 12

all the questions in this section are qualified helper questions, to see regular ones click open questions, @ILoveOpenStudy2

Answer 13

@hockeybeast10

Do you know what the x-axis and the y-axis is?

Answer 14

@ILovePuppiesLol I'm in the math section. :P

Answer 15

yup math section is split into 3 sections, open question section, qualified helper section, and closed question section

Answer 16

yes

Answer 17

i know that part but how would i explain that?

Answer 18

x-axis: individual people
y-axsis: arm span and height in inches

Answer 19

can that dog lick me?

Answer 20

hes cute

Answer 21

jk lol

Answer 22

You chose individual people for your x-axis

You chose Arm span and height in inches for your y-axis

You chose those because then you could should the difference of arm span and height among the different people.

Answer 23

@ILoveOpenStudy2 are you there?

Answer 24

Yes, for question #2

We have two lines to find the line of best fit.

Let's do one line first.

Can you find two points that are on that line?

Answer 25

i dont understand

Answer 26

do i just pick an arm length size?

Answer 27

For example, I drew a line. The point is (x, y) What is the x-value of the point? What is the y-value of the point?



We can start with the arm span line first :)
