The volume v of a given mass of a gas varies directly as a temperature t and inversely as the pressure p. if v=231cm^3 when t=300 degrees kelvin and p=20lb/cm^2, what is the volume when t=484 degrees kelvin and p=22lb/cm^2?

V = 338.8

Step-by-step explanation:

Basically manipulate the ideal gas law.

PV = nRT

We know n and R are constant so we can cross that out. We get:

PV = T or

Let's plug in the values to get:

We simplify them to get:

We cross multiply:

Simplify:

Solve for V by dividing both sides by 6,600.

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
