Mean is a form of average, and in order to find this we add up all the numbers then divide by the amount of numbers we have.
So, we have 5 numbers here. (8, 17, 9, 3, and 13)
8 + 17 + 9 + 3 + 13 = 50
50/5 = 10
The mean of those five numbers is 10.

The ratio of book price to number of pages for the ordered pairs a, b , and c are:
- <em>A = 0.05</em>
- <em>B = 0.05</em>
- <em>C = 0.043</em>
The ratio of book price to number of pages can be evaluated for each ordered pairs as follows;
Therefore, ratio of book price to number of pages for the ordered pairs a, b , and c are:
a = 0.05
b = 0.05
c = 0.043

Answer:
Answer: $210 profit
Step-by-step explanation:
275-65 =210
The original expression is equal to 0 because anything multiplied by 0 is equal to 0. Solve inside the brackets for the possible answer choices to find what will equal 0.
Start with the first expression. Add 4 and negative 4 will become 0, and -1 times 0 is equal to 0. Let's solve for the others just to be sure.
In the second expression, solving inside the brackets gives you 8. -1 times 8 is equal to -8.
Adding 4 and negative 4 in the third expression leaves you with 0. But, 1 + 0 is equal to 1.
Adding negative 4 and negative 4 gives you the answer of -8, and -1 times -8 is equal to 8.
Your answer is the first expression, or A.
