22+26+28+30+39+44+62+63= 314
Divide the answer by the amount of numbers
=39.25
F(11) means to replace x in the equation with 11
12(11) + 5
12 x 11 = 132
Now you have 132 + 5 = 137
F(11) = 137
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
F(x)=2(x+10)=24
2(x+10)=24
divide 2
x+10=12
minus 10
x=2
D
Answer:
x = 10
<u></u>
Step-by-step explanation:
2x - 4 = 16 try to get x on the left side, and the integers on the right
You then get:
2x = 20
Now, divide by 2 on both sides
2x/2 = 20/2
<u>x = 10</u>
