Answer:
The correlation coefficient of the data set is -0.901
Step-by-step explanation:
x y xx xy yy
1 20 1 20 400
3 14 9 42 196
5 10 25 50 100
9 6 81 54 36
15 4 225 60 16
Formula :
So, Option D is true
Hence the correlation coefficient of the data set is -0.901
Answer:
Step-by-step explanation:
f(x) = x²
1. Vertex ( 0 ,0)
2) a > 0 , opening upward
3) minimum
4) Axis of symmetry : x = 0
5) Range: y ≥ 0
Answer:
y = -16.25
Step-by-step explanation:
It can also be written as
-8y = 26 * 5
-8y = 130
y = 130/-8 = - 65/4 = -16.25
