Answer:
Mean and Variance of the number of defective bulbs are 0.5 and 0.475 respectively.
Step-by-step explanation:
Consider the provided information,
Let X is the number of defective bulbs.
Ten light bulbs are randomly selected.
The likelihood that a light bulb is defective is 5%.
Therefore sample size is = n = 10
Probability of a defective bulb = p = 0.05.
Therefore, q = 1 - p = 1 - 0.05 = 0.95
Mean of binomial random variable: 
Therefore, 
Variance of binomial random variable: 
Therefore, 
Mean and Variance of the number of defective bulbs are 0.5 and 0.475 respectively.
Answer:
The correct answer is 12 and a half or 13 weeks.
Step-by-step explanation:
First, convert the values to decimals.
27 1/2 = 27.5
2 1/4 = 2.25
Then, divide miles of road that need to be repaved by the number of miles that are repaved per week.
27.5/2.25 = 12.2222222222222
Round that up to 12 and a half weeks or 13 weeks.
In this number 1500,000,
1 is at million place and 5 is at hundred thousand place
So, the value of 1 = 1 (1,000,000) = 1 million
And the value of 5 = 5 (100,000 ) = 500,000 = Five hundred thousand
In the second number 100,500
1 is at hundred thousand place and 5 is at hundred place
The value of 1 = 1 (100,000) = 100,000 = Hundred thousand
And the value of 5 = 5 (100 ) = 500 = Five hundred
Since the digits 1 and 5 both are at different places in both the numbers so 1,500,000 and 100,500 are not the same.
Don’t click on the link, it is a virus.... the answer is 18 squared x 3.14
So then you get 324x3.14, and you get 1,017.36
That is ur answer
In similar triangles ratios of corresponding sides are constant, so
|AB|/|DE| = |BC|/|EF|
5/10 = 8/|EF|
|EF| = (8*10)/5 = 16
|EF| = 16
