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:
A = 8
B = 6
C = 4
D = 7
Top = 29
Side = 20
Step-by-step explanation:
To get A on the bottom side row you divide 32 by 4 and get 8.
To get D, on the first side row, subtract A, 8, now it's 21, 21 divided by 3 is 7.
To get B, on the first top row, subtract A and D, now divide by 2 and you get 6.
To get C, on the third side row, subtract B and divide by 2 and you get 4.
Answer: 8 inches
Explanation:
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
36 + b^2 = 100
b^2 = 64
(Have to find the square root of 64)
= 8 inches
Make more than a 80 on quizzes and you should be fine 75 lowest possible
Answer: The answer is D. -1, 2, 5, 8
Step-by-step explanation: Arithmetic means Add or Subtract. You are adding 3 to get your next number. If that makes sense?
