Answer:
16 for Sol A and 24 for Sol B
Step-by-step explanation:
Let x = the number of ounces of Solution A
Let y = the number of ounces of Solution B
x + y = 40 y = 40 - x
.60x + .85y = .75(40)
.60x + .85y = 30 Multiply both sides of the equation by 100 to remove the decimal points.
60x + 85y = 3000
60x + 85(40 - x) = 3000
60x + 3400 - 85x = 3000
-25x = -400
x = 16 ounces
y = 40 - 16
y = 24 ounces

What is the interquartile range of the data set?
8_murik_8 [283]
Answer:
IQR = 8
Step-by-step explanation:
The interquartile range (IQR) is the difference between the upper quartile Q₃ and the lower quartile Q₁
We require the data arranged in ascending order and to find the median Q₂
The median is the middle value of the data arranged in ascending order.
8, 9, 9, 9, 10, 11, 13, 15, 17, 18, 22
↑ Q₂
The upper quartile is the middle value of the data to the right of the median
13, 15, 17, 18, 22
↑ Q₃
The lower quartile is the middle value of the data to the left of the median
8, 9, 9, 9, 10
↑ Q₁
IQR = Q₃ - Q₁ = 17 - 9 = 8
Answer:
0.39
Step-by-step explanation:
39% can be written as 39.% to emphasize that the decimal is to the right of the last digit in a whole number. When converting from percent to decimal, you divide by 100 which has the same effect as moving the decimal two places to the left. Therefore, 39.% becomes 0.39.
C due to the fact that it is C and C is the correct answer
