Answer:
20 ounces = 1.25 pound = 1 1/4 pound
We easily see and can convert 1/5 of a pound is 0.25 pound
6/5 = 20 ounces = 1 1/5
5/5 = 1 pound
When we reverse for ounces we see
1 pound =16 ounces
1/4 pound is 4 ounces
1/2 pound is 8 ounces
3/4 pound is 12 ounces
1 1/4 therefore is 20 ounces.

Step-by-step explanation:
Previous concepts
The expected value of a random variable X is the n-th moment about zero of a probability density function f(x) if X is continuous, or the weighted average for a discrete probability distribution, if X is discrete.
The variance of a random variable X represent the spread of the possible values of the variable. The variance of X is written as Var(X).
Solution to the problem
Since the warranty on a machine specifies that it will be replaced at failure or age 4 and the distribution for X is defined between 0 and 5 then if we define the random variable Y ="the age of the machine at the time of replacement" we know that the values for Y needs to be between 0 and 4 or between 4 and and we can define the following density function:
for other case
Now we can apply the definition of expected value and we have this:
And for the second moment we have:
And the variance would be given by:
Solution:
The dimensions of the bedroom #3 are given below as
To calculate the area of the bedroom, we will us eth formula below
Hence,
The area of BEDROOM #3 is
Part B:
Given that the cost of the floor is
Hence,
The cost of floors of bedroom #3 is
This is not possible, unless x = 1.
