N-8 or 8-n I would assume
Answer:
I'm pretty sure the answer is B, I hope this helps!
Answer:
(B) The price for the lower level is $32.50 a ticket, plus $5.00 for a discounted parking pass. The middle-level tickets are $28.75 each, plus $20.00 for a parking pass.
Step-by-step explanation:
The answer is 5.5
The standard deviation (sd or σ) of the sample mean difference is:
sd = √(sd₁²/n₁ + sd₂²/n₂)
For the population A:
sd₁ = 17.6
n₁ = 25
For the population B:
sd₂ = 21.2
n₂ = 30
Hence:
sd = √(sd₁²/n₁ + sd₂²/n₂)
= √(17.6²/20 + 21.2²/30)
= √(309.76/20 + 449.44/30)
= √(15.49 + 14.98)
= √(30.47)
= 5.5
Volume of the pan = Length x width x height = 168 in^3
Volume of bar = L x W x H = 12 in^3
Then you should divide volume of pan/volume of bar
168/12 = 14 BARSSZZZZZZZ
