Question

Which of the following is the most appropriate model for the given data?

A scatter plot contains the ordered pairs 0,3 and 1,2 and 1.5,3.5 and 3,2.5 and 3,5 and 4,6 and 5,4 and 6,6 and 6,9 and 7,7 and 7,11 and 7.5,14 and 8,9 and 8,15 and 9,13.

ŷ = 1.25(2)x
ŷ = 1.4x + 0.5
ŷ = 2(1.25)x
ŷ = 0.5x + 1.4

Answer 1

@lui0210 might be able to help. c: <3

Answer 2

I just need to get my math done and not fail sobs

Answer 3

Have you tried plotting the points?

Answer 4

Well, if not, this is what you get

Answer 5

If you notice, it looks just slightly like an exponential curve. Which means you can eliminate equations that are linear (b, d)

Answer 6

I see

Answer 7

If you plot the last two, you can see that option C, is close to the points you plotted.
A has a steep rise

Answer 8

So, C would be the correct answer seeing as it isn't linear and doesn't have a steep rise but s=instead matches the points more than the rest?

Answer 9

Based on my few mins of putting 2 and 2 together, yes lol

But you might wanna check yourself by just plotting the equations. I would but I am in class atm..

Answer 10

Oh that's fine, thank you for helping me! I would ask if you could help me with a few more but I don't want to bother you while you're in class..

Answer 11

You can just post them as separate questions, someone else might be able to help (:
