Answer:
-32/35
Step-by-step explanation:
-4/5 ÷ 7/8
remember that the division by a fraction is the same as the multiplication with the inverse fraction :
-4/5 × 8/7
I think now it is easier to see what happens :
-4×8 / 5×7
please consider that a minus sign of a fraction can only be used once - either for the numerator, or for the denominator. never for both, because then the fraction as a whole would be positive ... (-/- = +).
so, the result is
-32/35

Answer:
So then we have approximately 14% of the values higher than 95.5
Step-by-step explanation:
For this case we assume that the info is given on the figure attached.
From this figure we have the following frequencies for each class
Class Frequency
___________________________
70.5-75.5 13
75.5-80.5 7
80.5-85.5 6
85.5-90.5 10
90.5-95.5 19
95.5-100.5 9
____________________________
Total 64
So we have a total of 64 values and we want to find the percentage of students that scored higher than 95.5 so we can use the formula of relative change and we got:
So then we have approximately 14% of the values higher than 95.5
