The answer is A. Let me know if you need an explanation.
32 cause it’s 32 it be 32 boo
g(x)=-2(x+3)^2
The -2 in front is the vertical stretch.
Also, because it is going 3 units to the left, you have to put the 3 on the inside and because it is left you do the opposite and it is +3.
The z-score is given by:
z=(x-μ)/σ
but
x-μ=52
thus
z=52/√84681
z=0.1787
Thus:
P(X≤52)=0.9633
The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y
So y is 4
