The average of 10 numbers is 85. If the numbers 70 and 76 are removed from the set of numbers, what is the average of the remain
Alexeev081 [22]

Answer:

88

Step-by-step explanation:

From the question:

The average of 10 numbers is 85.

We have to find the total sum for the 10 numbers

Hence: 10 × 85 = 850

If the numbers 70 and 76 are removed from the set of numbers.

This means 10 number is reduced by 2

= 10 - 2 = 8

The total sum of the 8 numbers is

= 850 - (70 + 76)

= 850 - 146

= 704

The average of the remaining numbers is calculated as:

Sum of the 8 numbers/8

= 704/8

= 88.

Therefore, the sum of the remaining numbers is 88

Me. Driscoll has 9 reports to grade. There are 6 page for each report. He grades 12 pages. How many pages does he still have to
ohaa [14]
So easy

so driscoll has 9 reports to grade and each page has 6 pages.

just multiply 9 and 6 which gives you your answer 54.

so out of 54, he has graded only 12 pages which means that you need to subtract.

54-12=42

driscoll has 42 pages left to grade.

you can recheck your answer by adding 42 ans 12 which gives your answer as 54. so yup our answer is right.
