A student scored 82, 95, 90 and 87 on his first 4 tests. What would he need to make on his 5th test to have an average 95.

Not gonna give an answer, sorry. Instead, I'll show you a similar example so you can be able to solve it.

An average test score is the sum of all the scores on an assessment divided by the number of test-takers.

For example, if three students took a test and received scores of 69, 87, and 92.

These numbers would be added together and then divided by three to get an average of 82.6.

I hope you know what to do now.

Step-by-step explanation:

(82 + 95 + 90 + 87 + x) / 5 = 95          Add  like terms on the left

(354 + x) / 5 = 95                                 Multiply by 5

354 + x = 95 * 5

354 + x = 475                                      Subtract 354 from both sides

x = 475 - 354

x = 121

On the first step, you need to add an x which represents the score he needs. You divide by 5 because that's how many scores there and and the 5 gives you an average.

what is the question here

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
