Step-by-step explanation:
Answer:
0.9769
Step-by-step explanation:
Given the data :
X : 7.5, 9.9, 4.8, 9, 8.1, 1.7, 3.1
Y : 35, 6, 45, 18, 20, 89, 84
The Correlation Coefficient obtained by using a graphing calculator to model the data above is : 0.9769, this means a strong positive correlation exists between the two variables.
Take any 2 points, so we'll us (2,16) and (4,32)
then do y2-y1/x2-x1
so 32-16=16
4-2×2
so then do rise(y) over run(x)
so the slope is 16/2 which simplifies to 8
so the rate of change is
y=8x
