The volume of this box can be given by
V=(12-2x)(10-2x)(x), or in simplified form, V=120x-44x²+4x³.
To find the volume of the box, we would subtract x from both ends of the length, so 12-2x. We also subtract x from both ends of the width, so 10-2x. The height of the box is given by the x amount that is cut out from the box. Volume of a box is given by length*width*height.
Answer:
81.85% of days would you expect the store to sell from 33 to 42 pairs of shoes
Step-by-step explanation:
The mean number of pairs of shoes sold by a shoe store is 36
Standard deviation =
We are supposed to find percent of days would you expect the store to sell from 33 to 42 pairs of shoes i.e.P(33<x<42)
Formula :
At x = 33
Z=-1
Refer the z table for p value
p =0.1587
At x = 42
Z=2
Refer the z table for p value
p =0.9772
So,P(33<x<42)=P(x<42)-P(x<33)=0.9772-0.1587=0.8185
Hence 81.85% of days would you expect the store to sell from 33 to 42 pairs of shoes
It would be 70r if you are using distributive property
