Mu=80, sigma=39, X=85
Z=(X-mu)/sigma = 5/39=0.128=0.13
P(X<=85)= 0.5517 (from Z-table)
so, P(X>85)=1-0.5517=0.4483 approx. thats 44.8% probability.

Answer:
278.63 square inches
Step-by-step explanation:
Gina needs to cut two types of rectangles.
Dimensions of one rectangle is given as,
Width = 12 inches
Length = =
inches
So, the area of this rectangular paper will be
Area = width × length = = 171 inches²
Dimensions of the other rectangular paper has been given as
Width = =
inches
Length = =
inches
So, the area of this rectangle will be
Area = width × length = = 107.63 inches²
Thus the total area she need to cut = 171 + 107.63 = 278.63 square inches.
