The correlation coefficient of a scatter plot with line of best fit shown will be the slope of the line.
We can eliminate last 2 choices because the line is clearly a downward sloping line and it's slope wont be positive.
From the first two, it looks like the plot's slope is very close to -1. So we take -0.91, instead of -0.35. <em>[note: 0.91 is more steeper than 0.35 (which is very relaxed)]</em>
ANSWER: -0.91
Answer:
26
Step-by-step explanation:
22*0.2=4.4
22+4.4=26.4
when you round you will get 26
(you should probably ask your teacher which way to round.)
Answer:
p = 1.25
Step-by-step explanation:
varies inversely
p (q + 2)² = k
-----------------------
Find k
p=5 when q = 3
5(3 + 2)² = k
5(25) = k
125 = k
----------------------
Find p when q = 8
p(8 + 2)² = 125
p(100) = 125
divide both sides by 100
p = 1.25
