Safari Adventure Theme Park is a self­guided theme park in which people drive through a park filled with African wildlife. They

are given a map and a written guide to the wildlife of the park. They charge $20.00 per car plus $2.00 per person in the car. The number of people per car can be represented by the random variable X which has a mean value μX = 3.2, and a variance σ2x = 1.4. What is the mean of the total amount of money per car that is collected entering the park?

Emily is making a meal for her family. She uses coconut milk for the dessert she is making.
Artyom0805 [142]

Answer:

576 cm^3

Step-by-step explanation:

Express this volume formula as V = π r^2 h, where the " ^ " symbol indicates exponentiation.  Substitute 4 for r (this is half the diameter), 12 cm for h, and 3 for π:  V = 3*(4)^2*12 cm^3, or V = 576 cm^3.
