First find out how much the 4 volleyball nets are by using 4*28 which would equal to 112. Now subtract 112 from 250 and that leaves you with 138. Then you divide 138 by 7 which will give you about 19.7 which you need to take all decimals out since it isn’t an whole number. The gym teacher can only buy 19 volleyballs.
First we need the total of both children and adults that like all the flavors:
12 + 5 + 20 + 23 + 11 + 16 = 87 total people
then find the number of adults that like sweet mint: from the table 11 adults like sweet mint
to find the probability divide the number of adults who like sweet mint by the total number of people:
11 / 87 = 0.126
the answer is A

Answer:
It should be Neither ordered pair is a solution
Step-by-step explanation:
I take the same math lol
A. z = 0.74
The z-score of 0.74 translates to a percentile of 0.77035. Hence, the area under the standard normal curve to the left of z-score 0.74 is ~0.77.
b. z = -2.16
This z-score translates to a percentile of 0.015386 which is also the numerical value of the area under the curve to the left of the z-score
c. z = 1.02
The percentile equivalent of the z-score above is 0.846. The area is also 0.846.
d. z = -0.15
The percentile equivalent and the area is equal to 0.44.
