Answer: A) 356.48m²
Step-by-step explanation:
divide up the shape:
square:
a=s*s
16*16=256m^2
Semicircle:
a = 0.5*πr²
(r would be half of a square side which is 8)
0.5*3.14*64=100.48
Add up the shapes:
100.48+256=356.48m²
Z - score:
z = X - Mean / Standard deviation
z = ( 25 - 24 ) / 1.3 = 1/1.3 = 0.7692
After that we will use the table for Normal Distribution:
z ( 0.7692 ) = 0.779
0.779 * 1,200 = 935
Answer: 935 boxes will weigh 25 oz or less.
