Answer: 500
Step-by-step explanation:
it is closest and is under 550. if it were 551 through 599 it would be 600
We have to find the unit rate, so we have to divide what you earned in interest by the amount of months.
120/8=15
So you earn $15 per month

Answer:
0.0143
Step-by-step explanation:
In this question, we are asked to use the binomial distribution to calculate the probability that 10 or fewer passengers from a sample of MIT data project sample were on American airline flights.
We proceed as follows;
The probability that a passenger was an American flight is 15.5%= 15.55/100 = 0.155
Let’s call this probability p
The probability that he/she isn’t on the flight, let’s call this q
q =1 - p= 0.845
Sample size, n = 155
P(X < A) = P(Z < (A - mean)/standard deviation)
Mean = np
= 125 x 0.155
= 19.375
Standard deviation = √npq
= √ (125 x 0.155x 0.845)
= 4.0462
P(10 or fewer passengers were on American Airline flights) = P(X \leq 10)
= P(Z < (10.5 - 19.375)/4.0462)
= P(Z < -2.19)
= 0.0143
Answer:
t cannot be -5 or 0 because these cause a 0 in the denominator and you cant divide by 0 that I'm aware of
4
I hope you have an awesome day
