Answer:
x = 16 when y = 40
Step-by-step explanation:
as y is directly proportional to x:
y = x
y = k x .........k is here constant.
15 = k * 6
k = 15/6
k = 5/2
Here constant, k is (5/2)
So when y = 40
y = k x
40 = (5/2)x
x = 40(2/5)
x = 16
Answer:
25%
Step-by-step explanation:
Based on the boxplot given ;
The boxplot can be summarized as follows :
Lower quartile, Q1 = 50 (starting point of the box)
Median (Q2), 50th percentile = 70 (vertical line in between the box)
The upper quartile marks the 75th percentile, Q3 = 81 (end point of the box)
The total distribution is 100% and hence, the percentage above the score 81 will be :
100% - 75% = 25%
