Answer:
12
Step-by-step explanation:
The interquartile range is the difference between the value at the right side of the box and the left side of the box, that is
interquartile range = 85 - 73 = 12
(a) The integral is equal to the area of the triangle; it has height 20 and base 10, so the area is 20*10/2 = 100.
(b) The integral is equal to the area of the semicircle with radius 10. It's also under the horizontal axis, so the area is negative. The semicircle has area 
, so the integral is -50π.
(c) First compute
which is the area of the triangle on the right. It has height and base 5, so its area is 25/2.
Then split up the desired integral as
and plug in the integral values you know:
Divide total earned by number of hours:

Answer:
0.90
Step-by-step explanation:
full price discounted total
month 1 49 1 50
month 2 120 5 125
month 3 101 24 125
total 270 30 300
full price discounted total
month 1 0.98 0.02 1
month 2 0.96 0.04 1
month 3 0.808 0.192 1
total x = 0.9 y = 0.10 1
x = 270 / 300 = 0.90
y = 30 / 300 = 0.10
Answer:
B. 9/91
Step-by-step explanation:
-81/9 = -2
9/81 = 1/9
√9 = 3
√81 = 9
B is the odd one out; it's a fraction.
