Answer:
Step-by-step explanation:
Perform the indicated multiplication (squaring):
-3(y^2 + 4y + 4) - 5 + 6y
Continuing with the multiplication:
-3y^2 - 12y - 12 - 5 + 6y
Combiing the y terms in descending order by powers of y:
-3y^2 - 6y - 17
Let the required weight be X, then
z = (X - mean)/standard deviation
2 = (X - 16)/1
X - 16 = 2
X = 2 + 16
X = 18 oz.
