Answer: -0.95
Step-by-step explanation:
The value that explains the least-squares regression line is 90% or 0.9, and is also r^2.
You would just square root r^2 and get r=0.948. since the relationship is negative, r= -0.948, or -0.95
Answer:
height = 12 feet
Step-by-step explanation:
r (radius of circle) = 7 ft
pi = 3.14 (in this context)
v = 1/3 * (or pi * radius squared) * h
r squared = 49 ft
v = 1/3 3.14 * 49 * h
v = 1/3 153.86 * h
3v = 153.86 * h
v = 196π
v = 615.44
3v = 1,846.32
1,846.32 = 153.86 * h
h = 12 ft.
5 1/2 = 5 5/10 and 1 1/5 = 1 2/10. 5 5/10 + 1 2/10=
6 7/10
The vector PQ is Q-P = (2, 1). The vector SR is R-S = (2, 2). One is not a multiple of the others, so the vectors are not parallel. In a parallelogram, these vectors would be identical. PQRS is
not a parallelogram.
