When you multiply 13.75 and 20.5 together, you get 281.875
Answer: 0.074
Step-by-step explanation:
Given : The total number of U.S. adults in the sample = 800
The number of U.S. adults dine out at a restaurant more than once a week = 216
The probability for an adult dine out more than once per week :-

If another person is selected without replacement ,then
Total adults left = 799
Total adults left who dine out at a restaurant more than once a week = 217
The probability for the second person dine out more than once per week :-
Now, the probability that both adults dine out more than once per week :-

You find volume by multiplying length times width so the answer would be 300
64x+24= 8(8x+3)
30x+70= 10(3x+7)
