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
No, in order for a right triangle to be similar it would need to have the same height and base.
Answer:20 quart

How many quart make 5 gallon
1 quart=0.25 gallon
5 gallon=5/025
5 gallon=20 quart
Answer:
$1920
Step-by-step explanation:
Original amount: £1200 x Simple interest rate: 0.2 x number of years: 3 = 720
Add Original onto simple interest
£1200 + £720 = £1920
Total Cost of personal loan after 3 years = £1920
