Answer
1) Relative frequency of prefering cold mocha amongst mocha drinkers = 0.32
2) Relative frequency of prefering a latte amongst hot coffee drinkers = 0.22
3) Type of coffee that has the highest percentage of people who prefer it cold = Regular
Explanation
1) Relative frequency of prefering cold mocha amongst mocha drinkers is given as
Relative frequency
= (Number of mocha drinkers who prefer it cold) ÷ (Total number of mocha drinkers)
Number of mocha drinkers who prefer it cold = 12
Total number of mocha drinkers = 12 + 25 = 37
Relative frequency = 12 ÷ 37 = 0.32
2) Relative frequency of prefering a latte amongst hot coffee drinkers is given as
Relative frequency
= (Number of latte drinkers who prefer it hot) ÷ (Total number of hot coffee drinkers)
Number of latte drinkers who prefer it hot = 19
Total number of hot coffee drinkers = 11 + 25 + 19 + 30 = 85
Relative frequency = (19/85) = 0.22
3) Percentage of people who prefer cold coffee for each coffee type
Regular
(17/28) = 60.7%
Mocha
(12/37) = 32.4%
Latte
(20/39) = 51.3%
Cappuccino
(27/57) = 47.4%
Regular coffee drinkers have the highest percentage of drinkers who prefer it cold.

Answer:
When x = 12, y = 4, and z = 2, 8x + 2yz = 112.
Step-by-step explanation:
8x + 2yz
Substitute variables given:
x = 12
y = 4
z = 2
8(12) + 2(4)(2)
Multiply 8 and 12.
96 + 2(4)(2)
Multiply 2 and 4.
96 + 8(2)
Multiply 8 and 2.
96 + 16
Add 96 and 16.
112.
The equation for that is y=2/3x+6
Mean:13 Median:12.5 Mode:12
