The average of 8 data values is -7. all but one are shown. find the missing value? a.-19
b.-17
c.-16
d.-14
e.-12

The answer for this is 9/1253decimal form 0.007

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
