Refer to the phase diagram of water and carbon dioxide..
1. What phase of water exists at 100°C and 5 atm?
2. What is the critical point for CO2 and water?
3. What phase of CO2 exists T-120°C? At 80°C and 100 atm?
Problem:
Five coins are tossed. Let G be the random variable representing the number of heads (H) that occur. Find the values of the random variable G.
What to find:
1. The number of possible outcomes or sample space (S). 2. The sample spaces (place in the table).
3. The correct values of random variable G.
4. Interpretation or description about the value of the random variable G.
Hydrogen gas is collected over water at total pressure of 95.0 kPa. The volume of gas collected is 28.0ml at 25 degrees Celsius. Determine the partial pressure of the hydrogen gas, if the water vapor pressure is 3.17 kPa
. For a box containing 4 black balls, and 2 green balls, 3 balls are drawn
in succession. Each ball placed black in the box before the next draw
is made . Let G be a random variable representing the number of
green balls that can be drawn. Find the values of random variable G
Find the standard deviation of the discrete random variable X with the following probability distribution, X={3, 2, 1, 0} and P(X) = {.125, .375, .375, .125}
In what phase is the substance at 50°C and 1 atm pressure?
consider a population consisting of 2,5,8,11,13 and 25. suppose sample of size 5 are drawn from this population.
A TELCO office has seven telephone lines. For the past months, the probability distribution of the random variable X which represents the number of busy lines per day, X={0, 1, 2, 3, 4, 5, 6, 7} P(X)={.02, .27, .06, .22, .15, .04, .08, .16}, what is the probability that the number of busy telephone lines in a day is fewer than six but at least one?
consider a papulation consisting 2,5,8,11,13 and 25. Suppose sample of size 5 are drawn from this population.
