Answer:
So, the probability is P=0.0097.
Step-by-step explanation:
We know that the number of flaws in a certain type of lumber follows a Poisson distribution with a rate of 0.45 per linear meter.
We conclude that λ=0.45.
We use the Poisson formula:
We calculate the probability that a board 3 meters in length has no flaws. We get that k=3.
We calculate:
So, the probability is P=0.0097.
You are finding the perimeter, which has double of each side length given.
Note: P = perimeter
2(5x - 1) + 2(2x + 1) = P
Distribute 2 to each monomial in the given parenthesis
2(5x - 1) = 10x - 2
2(2x + 1) = 4x + 2
10x - 2 + 4x + 2 = P
combine like terms.
P = 10x + 4x - 2 + 2
P = 14x
C) 14x, is your answer
hope this helps
In order to satisfy the requirement, this are the following that is required;First, at least one observation must be above or below 90 seconds. Second is ether the population is normally distributted or greater than (>) 30, or maybe both.
The answer in this question is A and B.
Answer:
45
Step-by-step explanation:
12 % of the marbles are blue, and
18 % of the marbles are green, so
30 % of the marbles are either blue or green.
There are 150 marbles.
30 % × 150 = 0.30 × 150 = 45
The number of blue or green marbles is 45.
