Step-by-step explanation:
We have it that x follows a poisson distribution.
λ is equal to 3
The poisson distribution is given by:
P(x) = e^-λ * λ^X/X!
λ = 3
X = 4
A. The question had already given us the X value to be 4
p(x = 4)
= e^-3 x 3⁴/4!
= e^-3 = 0.001
3⁴= 34
4! = 81
putting all values into p(x=4)
= .001x81/24
= 0.1680
b. for 3 good hours, we will have lamda to be;
3x3 = 9
p(x = 6)
= e^-9 * 9⁶/6!
= 0.0911
To convert meters per minute to kilometers per hour, which of the conversion factors would be used? d. 60sec/ 1min
Area = 8,100 square feet
area of a square = a²
8,100 square feet = a²
√8,100 square feet = √a²
90 feet = a
total length each row of bookshelf is 4/5 of the length of the storage space.
90 feet * 4/5 = (90*4)/5 = 360/5 = 72 feet.
Area = (72 ft)²
Area = 5,184 square feet.
