Murilo bought 8 pizzas for his baseball team to share equally after the game. Each pizza has 6 slices, and the expression representing the situation is StartFraction 48 over p EndFraction. Which of the following evaluations of the expression are correct? Check all that apply.
If p = 10, then each player will get 4 slices of pizza, with 2 slices left over.
If p = 12, then each player will get 4 slices of pizza, with no slices left over.
If p = 15, then each player will get 3 slices of pizza, with no slices left over.
If p = 15, then each player will get 3 slices of pizza, with 3 slices left over.
If p = 16, then each player will get 3 slices of pizza, with no slices left over.
Answer: The correct evaluation of the expressions is If p = 12, then each player will get 4 slices of pizza, with no slices left over and If p = 15, then each player will get 3 slices of pizza, with 3 slices left over.
If Murilo buys 8 pizza and each pizza has 6 slices, the total number of slices can be determined by multiplying 6 by 8. 6 x 8 = 48. There are a total of 48 slices of pizza.
In order to determine the number of slices of pizza that each player would get, divide the total number of slices by the number of player.
If p = 10, each player would get : 48 / 10 = 4 with 8 slices left over.
If p = 12, each player would get : 48 / 12 = 4 with 0 slices left over.
If p = 15, each player would get : 48 / 15 = 3 with 3 slices left over.
If p = 16, each player would get : 48 / 16 = 4 with 0 slices left over.

Circumference = 43.98cm
A six-sided number cube is rolled 900 times.
How many times is it expected that a number greater than 4 will be rolled?
Answer: Rolling a die and obtaining a number follows a binomial distribution.
Expected value of binomial distribution is
E[X]=np
where n is number of toss and p is probability of obtaining the number.
Therefore here the expected value of obtaining a number 4 is:
E[X]=900∗16=150
Step-by-step explanation:
It is expected that a number greater than 4 will be rolled 300 times
The sample space of a die is:
S = {1,2,3,4,5,6}
The probability of obtaining a number greater than 4 is:
[tex]p = 2/6[/tex]
[tex]p = 1/3[/tex]
In 900 rolls, the expected number of number greater than 4 is:
[tex]E(x) = p *n[/tex]
This gives
[tex]E(x) = 1/3 *900[/tex]
[tex]E(x) =300[/tex]
Hence, it is expected that a number greater than 4 will be rolled 300 times

fewer than twelve decreased by eight
Answer:
Given:Four times a number decreased by ten is eight less than twice the number.
What To Do:We have to form the equation and solve to find the value of a number.
Solution:Let the number be x.
According to the statement,
The equation will be,
⇒ 4x 10 = 2x - 8
Take 2x to LHS and 10 to RHS,
⇒ 4x-2x = - 8 + 10
Solve the brackets,
⇒2x = 2

Polynomial functions use only whole numbers as exponents of the variables. Rational functions use variables with exponents in the denominator. But a fraction with exponents in the denominator is equivalent to using a negative exponent and this violates the definition of a polynomial.

Let A and Y be the numbers of Adult and Youth tickets.
We can calculate total sales with:
25A + 15Y = Total Sales

A five foot tall girl casts a 7 foot long shadow. A nearby telephone pole casts a 35 foot long shadow. What is the height of the telephone pole?
Answer: the height of the telephone pole is 25 feet.
Step-by-step explanation:
First, make a proportion as such: 7/5=35/x. You are solving for x. Next, figure out what number multiplied by 7 is 35. The number is 5. Now, multiply 5 by 5, and that is the answer.
7/5=35/x
x=25
7/5=35/25
To doublecheck, you can divide both 35 and 25 by 5.
35/5=7
25/5=5
If you get 7/5, then the answer is correct.
Answer:
25 feet
Step-by-step explanation:
1. Set up a proportion
[tex]\frac{5}{7}[/tex] = [tex]\frac{x}{35}[/tex]
x = the height of the telephone pole
2. Cross multiply
5 * 35 = 175
7 * x = 7x
175 = 7x
3. Solve for x
25 = x
The height of the telephone pole is 25 feet.
