Mark has taken 3 tests this semester and his average is a 78%. He really wants to get his test average to an 80% after his next test. What does he need to get on test
#4 to do that?

I would say 82 but it depends on how much each test was worth.

Step-by-step explanation:

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
