In her seventh grade pre-algebra class, ms. cornelius gave a standardized exam prepared by the district math department. students' scores on the exam were as follows:
100, 98, 98, 96, 96, 96, 94, 92, 88, 82.
what is the mean score?

94

Step-by-step explanation:

The mean is the average of the numbers,

To find the mean add all the numbers and divide by how many numbers there are i.e count the numbers

In this case lets find the sum;

Sum = 100 + 98 + 98 +96 + 96 + 96 + 94 + 92 + 88 + 82

       = 940

Count the numbers : There are 10 numbers in total.

Therefore, The mean = 940/10

                                    = 94

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
