Answer:
63
Step-by-step explanation:
Follow PEMDAS, as well as the left -> right rule.
Note that PEMDAS is the order of operations in which you should solve, and =
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
First, look at the problem. The problem gives you:
42 ÷ 2 x (11 - 8)
Using PEMDAS, first, solve the parenthesis:
11 - 8 = 3
Next, use the left -> right rule to solve the rest.
42 ÷ 2 x 3
(42 ÷ 2) x 3
(21) x 3 = 63
63 is your answer.

The mean is the sum of all numbers divided by the number of numbers. We can set up an equation:

Where 'x' is the next quiz score she need. Solve for 'x'. Multiply 5 to both sides:

Add:

Subtract 322 to both sides:

So her next quiz score needs to be 73 in order to have a mean score of 79 on all her quizzes.
