Answer:
Average of height of the building = 1.493.
Step-by-step explanation:
We have given the different heights of the buildings are 1.667, 1.483, 1.483, 1.451, 1.381.
We need to find the average height of the building by given data.
We know the formula of the average, as following:
Average =
According to the question,
Average of height of the building =

Answer:
Step-by-step explanation:
Given
-- total
--- defective
--- selected
Required
The probability of rejecting the batch
This means that at least one of the selected piece is defected.
So, we first calculate the probability that all the selected piece are accepted.
So, we have:
The denominator decreases by 1 because it is a probability without replacement; 180 is subtracted from the numerator to represent the number of non-defective CDs
So, we have:
Using the complement rule, the probability that the batch will be rejected is:
The graph shows the solution to be (x, y) = (-1, 3).
