avg. service time = 2hrs +/- 32 mins = 180 mins +/- 32 mins = 148 mins or 212 mins.
Random sample = 64/400 = 16 % of the total population.
Seriously I dont know the answer to the problem, but it is an interesting question, and it forces me to study probability more.
Answer:
she needs 1/3 chocolate bars
Step-by-step explanation:
8 × 2/3
=5 1/3
The scale given (1 in : 1/2 ft) implies that 1 inch on the model is equal to 1/2 foot on the actual ship. Therefore, we can multiply the two inch values by 1/2 foot to find the true dimensions of the ship in feet. Starting with 28 inches:
28 × (1/2 ft) = 14 ft
28 inches is proportional to 14 feet. Now calculate 65 inches:
65 × (1/2 ft) = 32.5 ft
65 inches is proportional to 32.5 feet. Therefore, the answer to this problem is:
D) 14 ft. by 32 1/2 ft.
I hope this helps!
The order would be 1/5,5/8,2/3.
