Question

What should be the score of test 6 to make an average score of 75?

Answer 1

Hello there,

Hope you're fine.

For the average to be 75, the total no. of marks have to be 450 and the number of tests is 6.

450/6=75

Thanks

Answer 2

average = sum of observations/ total number of observations

here we have to find the score of text 6 to make an average score of 75.

means, average is given 75.
total number of observations = 6
we have to find sum of observations = ?

so, 75 = sum of observations/6
sum of observations = 75 × 6 = 450
hence, answer should be 450.
