Answer:
Complement: 67°
Supplement: 157°
Step-by-step explanation:
Complementary angles = 90°
90-23=67°
Supplementary angles = 180°
180-23=157°

Step-by-step explanation:
4. (6^10)^-7 is when the exponents should be multiplied
answer is B
5. (7^3)^-2 = (7^-6)
1/7^6 = 1/(7x7x7x7x7x7)
answer is A
2. 11^-4/11^8= 1/11^(8+4) = 1/11^12
answer is A
3. (2^5/3^2)^4= 2^20/3^8
answer is A
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:
(p green) 1/3
(p red) = 1/2
Step-by-step explanation:
Add the number of balls together to get the total.
3 + 7 + 5 = 15
Find the probability of choosing green.
(p green) = 5/15
reduce by 5
(p green) 1/3
Since you kept the green ball, there are now a total of 14 balls.
Find the probability of choosing red.
(p red) = 7/14
reduce by 7
(p red) = 1/2
