Answer:
F=2x^2+24
Step-by-step explanation:
F (x+3)=2x^2+6
F=2(x+3)^2+6
F=2(X^2+9)+6
F=2x^2+18+6
F=2x^2+24

Answer:
168 = x
Step-by-step explanation:
mean = u=132
standard deviation =sigma = 20
z score =z=1.8
The formula is
z = (x-u)/ sigma
Substituting what we know
1.8 = (x-132)/20
Multiply by 20
1.8*20 = (x-132)/20 *20
36 = x-132
Add 132 to each side
36+132 = x-132+132
168 = x
