Question

An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment values shown in the table below:


Enrollment Month
January February March April May June
Actual 500 400 550 550 750 400
Predicted 410 450 650 650 600 450
Residual 90 −50 −100 −100 150 −50


Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals ar

Answer 3

Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit.
No, the equation is not a good fit because the sum of the residuals is a large number.
No, the equation is not a good fit because the residuals are all far from zero.
Yes, the equation is a good fit because the residuals are not all far from zero.
Yes, the equation is a good fit because the sum of the residuals is a small number.

Answer 4

@welshfella help please :))

Answer 5

@welshfella

Answer 6

i don't know sorry. i guess i've done this in the past but i can't remember
the sum of the residuals is - 60 which does not seem too bad but the residuals themselves are all far from zero. i would guess that b is the correct option.

Answer 7

Mind screen shotting the question?

Answer 8

i do not know how srry?

Answer 9

well i do but my computer (mac) is stupid so :(

Answer 10

I agree I hate mac lol...
I just asked because I don't really understand the graph and I don't see the equation for the line of best fit...

Answer 11

ok i will jut draw lol

Answer 12

lol okay

Answer 13

there you go srry it took so long

Answer 14

@undeadknight26 ?

Answer 15

Thanks! Btw do you have the equation?

Answer 16

?

Answer 17

there was no equation it was just the table and then answer choices :)

Answer 18

That's weird....There should be an equation for the line of best fit...Or many that may be because quite a bit of the answer is missing lol

Answer 19

lol

Answer 20

it says that the equation was used to predict the dance studio enrollment values shown (the table i gave you) I hope that this helps lol? @undeadknight26

Answer 21

I think it would be no it's not a good fit mostly because all the residual is far from 0...Or B.

Answer 22

ok ty :)

Answer 23

Please tell me if it's right or wrong when you find out :)

Answer 24

ok crossing my fingers :D

Answer 25

YES!

Answer 26

Awesome :D
