Answer:
100cubic inches
Step-by-step explanation:
varies inversely
pv = k
Find the constant of variation:
volume of 180 cubic inches under a pressure of 5 pounds
5 * 180 = k
k = 900
volume if the pressure is increased to 9 pounds per square inch?
9v = 900
divide both sides by 9
v = 100

Step-by-step explanation:

Answer:
740 m^2
Step-by-step explanation:
Part A
Use the binomial probability distribution formula.
p = 0.54 = probability of getting a purple marble
n = 5 = sample size
x = 2 = number of purple we want to get

The
portion is from the nCr combination formula. The exclamation marks indicate a factorial.
Alternatively, you could use Pascal's Triangle for that portion.
<h3>Answer: 0.283831776</h3>
This decimal value is exact. Round it however you need to.
============================================================
Part B
To find the expected value, aka the mean, we multiply the sample size and probability of getting a purple marble on any single selection.
n*p = 5*0.54 = 2.7
<h3>Answer: 2.7</h3>
