(Please provide an explanation as well if you can, I'm pretty confused on how you would find this out on any other problems)

The mean of the test grades of 50 math students is 85%. Two students scored 10% on the test. If those outliers were removed, what would be the new mean?

88%.

Step-by-step explanation:

Total scores = 85 * 50 = 4250.

Take the 20 marks the 2 students scored away gives us 4230,

To find the new mean we divide by 48:

4230 / 48

=  88%.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following
