Answer:
608 ft^2
Step-by-step explanation:
The formula for calculating surface area of a triangular prism is
bh + 2ls + lb (b : base, h : height, l : length)
12×8 + 2×16×10 + 16×12 = 608 ft^2

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:
C
Step-by-step explanation:
5ax²-20x³+2a-8x
=5 x²(a-4x)+2(a-4x)
=(a-4x)(5x²+2)
Answer:
H. 3 units
Step-by-step explanation:
In order to answer this question, we have to apply the formula for the sphere volume. The formula is:
Plugging the given number into V, we calculate that:
If π=3.14, the radius is:
r ≈ 3 units.
