Answer:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409.
Step-by-step explanation:
We can model this question with a binomial distribution random variable.
The sample size is n=60.
The probability that the relay come from supplier A is p=2/3 for any relay.
If we use a normal aproximation, we have the mean and standard deviation:
The probability that at most 38 of the 60 relays are from supplier A is P(X≤38)=0.3409:
Answer:
Total Area = 236.715 sq ft
Step-by-step explanation:
this is a composite figure made up of a circle and a rectangle; find the area of each and then add them together
A(circle) = πr²
= π(7.5²)
= 176.715
A(rectangle) = 15(4) which is 60
Total Area = 236.715 sq ft

Answer:
Part A: 7.58974359 gallons (I don't know if you needed to round so I kept the full number).
Part B: 8.871794872 gallons
Step-by-step explanation:
Part A's Steps:
First Step: 350 - 54 = 296
Second Step: 296 ÷ 39 = 7.58974359 (Round if you need to)
Part B's Steps:
First Step: 296 + 50 = 346
Second Step: 346 ÷ 50 = 8.871794872
