Answer:
C = 37.7 inches
Step-by-step explanation:
You are looking for the circumference.
Formula for the circumference-> C=2πr
variables:
c = circumference
r = radius
You have the diameter, which is 12 inches. Radius is half of the diameter. which means r is half of 12 (aka 6).
put the radius where the variable is in the formula.
C=2π(6)
you now have enough information to solve for circumference.
C = 2 * π * 6
C = 37.7
It'll be 60 if you divided there is your actually answer
Answer:
108.88
Step-by-step explanation:
Given that:
Equation of Regression line obtained for couple's IQ:
y=9.88+0.9x
x represents the IQ score of the husband
The best predicted IQ of wife Given that husband's IQ is 110
y = 9.88 + 0.9(110)
y = 9.88 + 99
y = 108.88
