Answer:
1.5, 20, 40, 7.5
Step-by-step explanation:
The first one is 1.5, the second one is 20, the third is 40, and the fourth is 7.5
3) This is definitely a positive association, but the question is - is it linear?
Since a somewhat straight line can be drawn through the points, it is linear.
<span>
Answer: positive linear association </span>
4) Find the slope using the formula

m = 43 - 48/ 4 - 2 = -5/2 = -2.5
Negative association, but is it linear? Lets find out
Oh no! It seems that their is not a pattern in the association, so its nonlinear!
Answer: Negative nonlinear association5) <span>

m = 80 - 66/ 5 - 3
m = 14/2
m = 7
Positive! But is it linear??
Let us draw a graph this time.
I know my graph is messy, but can you see the nonlinear-ness? It doesnt form a straight line!
Answer: Positive nonlinear association </span><span>Hope this helped. :) </span>
Answer:
Step-by-step explanation:
x is one-half the value of its intercepted arc. Therefore, x is 110/2 which is 55. Second choice down is the one you want.
