Answer:
The answer is
for p<5
F(p)=50-p(12.25)
Step-by-step explanation:
First we stablish that 4 is the maximun number of pizzas he can buy as
50/12,25 = 4,08
then we know that he will receive change iqual to the original amount he has less the number of pizzas he buy multiplied for the cost of each pizza.
Take an example: The salary per hour:
Assume x (variable) is the number of hours worked and assume THAT THE RATE PER HOUR IS $10, then:
If you work x hours at the hourly rate of$10, you will generate an income,
say, y that is equal the number of hours worked by the rate per hour, that is:
y = 10.x. The more hour(x) you work, the more income(y) you get.
Hence we created a relationship between y and x , or in English, between the earning and the number of hours worked.
Moreover y depends on x, if there is no x, there is no y and if x increases, y increases. However x is an INDEPENDENT variable because you can
give to x any number & y will follow
Simplifying rational expressions will make the further calculations easier since the variables to work with will usually be smaller.
To determine that a rational expression is in simplest form we need to make sure that the numerator and the denominator have no common variables.

Given
--- proportion
-- sample
Solving (a): The mean; E(x)
This is calculated as:
Substitute values for n and p
Solving (b): The variance; s^2
This is calculated as:
Substitute values for n and p
Solving (c): The standard deviation; s
This is calculated as:
Substitute value for s^2
