Cory’s average score after 8 tests is 91%. If he gets a 78% on his 9th test what will his new average be?

Answers

Answer 1

Answer:

The new average will be 89.55%.

What is an average?

The average is defined as the mean value which is equal to the ratio of the sum of the number of a given set of values to the total number of values present in the set.

It is given that,

Average score after 8 tests = 91%.

Therefore, Total score of 8 tests = Average score*Number of tests

Total score of 8 tests = 91*8

Total score of 8 tests = 728

Now, Cory scored 78% in 9th test,

So, Total score of 9 tests = Total score of 8 tests + 78

Total score of 9 tests = 728 + 78

Total score of 9 tests = 806

Hence, Average score of 9 test = Total score of 9 tests/9

Average score of 9 test = 806/9

⇒ Average score of 9 test = 89.55%

Hence, the new average will be 89.55%.

Am I corectWhat is the fraction 8/36 expressed in lowest terms? I got 2/9 thats my final answer

Answers

I'm going to say yes. But just check. $(8)/(36)$ can both be divided by 4. So when divided you get $(2)/(9)$ and 2 can't go into 9, so yes that is your lowest term.
