Question

Farmer Brown had 6 water wells drilled on his land. The drillers charge by the foot in terms of the depth of the well, plus fees for labor, parts, and fuel. The points on the scatter plot below show the cost of the six wells as well as their depth. The red line has been fit to the data for estimation and prediction.



Which of the following statements are valid representations of the meaning of the 1000 in the equation of the line?

Answer 1

Valid Not Valid
A 1000 is the predicted cost of a well without any charge based on the depth of the well.
B 1000 is the slope of the prediction line.
C 1000 is the y-intercept of the prediction line.
D 1000 is the predicted number of dollars the cost increases by for every additional foot of depth.

Answer 2

so A is false

Answer 3

B is false
C is true
and D is true?

Answer 4

On A, put 0 in for x in y = 5x + 1000 and see what you get.

Answer 5

i get 1000

Answer 6

@Directrix internet problems again?

Answer 7

No. I asked you a question and saw no reply. I went off to help an OP.

Answer 8

If you get 1000, then why is question A false?

Answer 9

because for the last one I got I got 1400 and you said it was false and it was correct

Answer 10

I need to look at that problem. Which one of the golf course problems was it?

A, B, C, or D?

Answer 11

yes the one that talked about the puff and the green

Answer 12

Which question? A?

Answer 13

yes

Answer 14

It's your work so go with what you think.

For this, I have:

T
F
T
F

Answer 15

ok thank you :)

Answer 16

On A, put 0 in for x in y = 5x + 1000 to get 1000.

Startup cost is 1000 before the drilling starts.

Answer 17

I'm just missing 2 more from this lesson to have 15 questions and have 90%+

Answer 18

That is why I chose T for part A of this question.

Answer 19

ohh ok that makes sense so is like a regular line and y=mx+b equation?

Answer 20

Did you miss the entire golf course problem because one of the 4 associated questions was wrong?

Answer 21

Yes, and I did the same sort of reasoning on part A of the golf course question. So, I don't know what to tell you.

Answer 22

i don't know how I didn't get that either I'm sorry :(

Answer 23

and your answers were correct for the golf question

Answer 24

y = 5x + 1000
y = 5*0 + 1000
y = 1000

The tricky thing here is how the question is worded:

A 1000 is the predicted cost of a well without any charge based on the depth of the well.

1000 is NOT the predicted cost of the entire well project.

Therefore, a person could argue False on part A.

Answer 25

it showed as correct but that website has some issues most of the time even when they give you the step by step solution they tell you something like
1. 1+2X=7
and then do 7-1=?
and then when you put 6 they will tell you wrong and then on the next step it would show as
2.7-1=6
6/2=?

Answer 26

so the have to still fix stuff but your answers have been correct so far thank you very much :)

Answer 27

The A part question on the well problem is not analogous to the A part question on the golf course problem.

This is a weird-i-o question. We'll just have to move on and do our best.

Answer 28

yeah I agree :)

Answer 29

Did you check the well digging answers?

Answer 30

yes :)

Answer 31

Alrighty, then. Time to move on.

Answer 32

yup :)
