Answer:
It would be 12 feet wide.
Step-by-step explanation:
Dancing pools sells swimming pools in 4 sizes.
All the poos have lengths that is 4 times long of their width.
The small pool is 36 feet long and 9 feet wide = 9 × 4 = 36
The medium pool is 40 feet long and 10 feet wide = 10 × 4 = 40
The Large pool is 44 feet long and 11 feet wide = 11 × 4 = 44
As we can see all the pool has 4 times longer length from it's width.
If the new super duper coffee table pool is 48 feet long, it's width would be 1/4 of its length. = 48 × = 12 feet
It would be 12 feet wide.

Step-by-step explanation:
The required probability will be found by using the Binomial Distribution which fits the case of n independent events each with a probability of success equal to p with k successes.
The PMF (Probability Mass Function) is
Where
LabTech states that the probability that a microscope is defective is 0.17%, p=0.0017, q=0.9983. We need to know the probability that k=1 microscope is defective out of a set of n=50 of them. We now apply the formula
Which means that there is a 7.82% of probability to get 1 defective microscope out of the first 50
