a. The reason why this question is a binomial experiment is based on the fact that it is made up of an independent sample, it has a number that is fixed and a probability.
Each event is made up of two outcomes and they are random with the same success rate.
<h3>b. How to solve probability that exactly 5 had a bachelor</h3>
we have the following data n = 12, p = 0.27 and k = 5
We have to use the function to solve electronically
binompdf(n,p,k)
input the values
= binompdf(12,0.27,5)
This gives us
= 0.1255
<h3>(C) Probability that fewer than 5 have bachelor</h3>
We use the formula below
= binompdf(12,0.27,5-1)
This is = 0.7984
D. Probability of at least 5
1 - probability of fewer than 5
= 1 - 0.7984
= 0.2016
How to solve for the Mean = n*p
n = 12 , p = 0.27
Mean = 12*0.27 = 3.24
and
standard deviation = √npq
n = 12, p = 0.27 , q = 1- 0.27
= 0.73
sd = √12*.27*.73
= 1.54

Answer:576
Step-by-step explanation:
Just do 144×4 and then you get 576 hopefully I helped
<u>Answer:</u>
The correct answer option is 21.
<u>Step-by-step explanation:</u>
We know that the given lines PW and AD intersect at the point C.
Therefore, the two given angles are equal to each other and we can write them in the form of an equation as:
(4x - 4)° = (3x + 17)°
Solving for x to get:
4x - 4 = 3x + 17
4x - 3x = 4 + 17
x = 21
Therefore, the value of x is equal to 21.
Answer:
8 hours
Step-by-step explanation:
Let t hours be the time needed Sonya to catch up Brianna.
Sonya:
Time = t hours
Rate = 44.8 mph
Distance 
miles
Brianna
Time 
hours
Rate = 32 mph
Distance 
miles
Note that 
because Sonya must catch up Brianna.
Use formula 
Hence,
