amid [387]

Step-by-step explanation:

A can is a cylinder.

Volume of a can = Volume of Cylinder

= \pi {r}^{2} h

Given Radius = 3.2 inches and height = 15 inches,

Volume of one olive oil can =

\pi( {3.2}^{2} )(15) \\  = 153.6\pi {in}^{3}

Volume of 5 olive oil cans = 5 x volume of one olive can

= 5 \times 153.6\pi \\  = 768\pi {in}^{3}

I will just leave the answer in terms of pi as I'm not sure if you need to round off your answers.

laila [671]
<span>Randomly generate an integer from 1 to 7 two times, and the probability is 1/7 ^2

This is the </span><span>statement that best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday.

There are 7 days in a week, so there are 7 choices but only 1 Monday. So, 1/7 is the probability that a person's birthday falls on a Monday.

1st person asked will have 1/7 probability.
2nd person asked will also have 1/7 probability

So, (1/7)</span>² is the probability that both persons will have their birthdays on a Monday.
