Answer:
207 square feet.
Step-by-step explanation:
The mural is going to be 50 feet wide. Means the diameter will be 50 feet.
So, the radius will be feet
One sector of the mural spans 38 degrees.
The ratio of the area of a sector to the area of the full circle equals the ratio of the degree measure of the given arc to 360.
Area =
=
= 207.15 square feet
To the nearest will be 207 square feet.

4" x 2500 ft², namely 4 ft x 2500 ft², will just be 4*2500*ft*ft², or 10000 ft³.
since there are 27 ft³ in 1 yd³, then how many yd³ are there in 10000 ft³?
10000/27, that many yd³.
since there are 27 ft³ in 1 yd³, then how many yd³ are there in 10000 ft³?

Answer:
0.0025 = 0.25% probability that both are defective
Step-by-step explanation:
For each item, there are only two possible outcomes. Either they are defective, or they are not. Items are independent of each other. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
5 percent of these are defective.
This means that
If two items are randomly selected as they come off the production line, what is the probability that both are defective
This is P(X = 2) when n = 2. So
0.0025 = 0.25% probability that both are defective
