PLEASE PLEASE PLEASE TELL ME HELP HELP
grin007 [14]

Answer:

78%

Step-by-step explanation:

Ok to solve this we can write this as

80 = \frac{73+82+85+83+x}{5}

We put the equation like this because were finding out how much he needs to get on his 5th test x in order to get a 80%

Your grade is the average of all of your scores hence the divided by 5

We next multiply both sides of the equation by 5 to get

400 = 72+82+85+83+x

400=  322+ x

78 = x

He must get a 78% minimum on his next test to get 80%

Hope that helps!

The test scores for 8 students taking and algebra 1 test are as follows: 56, 92, 78, 64, 85, 83, 91, 77. what would the 9th stud
crimeas [40]
X= 9th student test score

Add the 9 test scores and divide that total by 9 to equal the average.


(56 + 92 + 78 + 64 + 85 + 83 + 91 + 77 + x)/9= 78
add in parentheses

(626 + x)/9= 78
multiply both sides by 9

626 + x= 702
subtract 626 from both sides

x= 76


ANSWER: 76 is the score needed by the 9th student for a mean of 78.

Hope this helps! :)
