Answer:
1. B (40- 3n)
2.c (86)
Step-by-step explanation:
1. The shirts cost 3n. So you do 40- 3n(what the shirts cost) to find the amount of change he will recive.
2. Just plug the numbers in- 1.8(30) + 32=86.
Answer:
16.67
Step-by-step explanation:
Each side is about 4.167 yards so the perimeter is roughly 16.67 yards
Answer:
0.087
Step-by-step explanation:
Given that there were 17 customers at 11:07, probability of having 20 customers in the restaurant at 11:12 am could be computed as:
= Probability of having 3 customers in that 5 minute period. For every minute period, the number of customers coming can be modeled as:
X₅ ~ Poisson (20 (5/60))
X₅ ~ Poisson (1.6667)
Formula for computing probabilities for Poisson is as follows:
P (X=ₓ) = ((<em>e</em>^(-λ)) λˣ)/ₓ!
P(X₅= 3) = ((<em>e</em>^(-λ)) λˣ)/ₓ! = (e^-1.6667)((1.6667²)/3!)
P(X₅= 3) = (2.718^(-1.6667))((2.78)/6)
P(X₅= 3) = (2.718^(-1.6667))0.46
P(X₅= 3) = 0.1889×0.46
P(X₅= 3) = 0.086894
P(X₅= 3) = 0.087
Therefore, the probability of having 20 customers in the restaurant at 11:12 am given that there were 17 customers at 11:07 am is 0.087.
Answer:
$72 earned on monday
Step-by-step explanation:
Delta pays Pete Rose $360 per day in the maintenance department at air port. Pete became I'll Monday and went home after 1/5 of a day
Delta works for only 1/5 of the day
To get the amount earn , multiply the work done by the rate

So $72 earned on monday
