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:
5087.75
Step-by-step explanation:
8.25/100=0.0825*4700=387.75 +4700=5087.75+775=5862.75
Answer:
24
Step-by-step explanation:
The cake measures 10 inches by 15 inches. If pieces are 2.5 inches long and wide (they are square and equal) then 6 pieces will be cut along the length.
15/ 2.5 = 6
And 4 pieces will be cut along the width.
10/ 2.5 = 4
All together when the entire cake is cut, there will be 4*6 = 24 squares 2.5 inch long pieces.
1.5 / 2 = 1 / x # cups / weight = # cups / weight
<span>cross multiply </span>
<span>1.5x = 2 </span>
<span>divide both sides by 1.5 </span>
<span>x = 1.3(the 3 keeps going) or 1 and 1/3 pounds
So the answer is 1/3

The answer isnt on there? unless it's A
Rise Over Run
From Yint you go up two and left two making your answer 2 over -2 but that would just be -1 making your answer y=-x
