The require set (CUD)' and C'nD is {q, r, x, y} and Ø.
<h3>Set theory</h3>
Sets are elements arranged in a specific pattern or way. Given the expression below;
U= {f, k, q, r, s, x, y }
C={f, s,y}
D = {f,x)
CUD is the union of two sets and given as:
C U D = {f, s, y, k}
(CUD)' = {q, r, x, y}
For the set C'nD
C' = {k, q, r,x}
C' n D = Ø.
Hence the require set (CUD)' and C'nD is {q, r, x, y} and Ø.

Answer:
You make $32,000 a year and want to save 10% of your income every year. How much should you put into savings every month?
$32$,000 x 0.10 = 3,200
You want to save $3200 a year.
You should be saving $266.67 a month or $133.33 a paycheck if you are paid
Step-by-step explanation:
Answer:
(351.04, 368.96)
Step-by-step explanation:
Given that population mean= 360
Std devitaion = 4
margin of error = 2.5%= 0.025
Since population std deviation is known we can use Z critical value
For two tailed critical value for 2.5% would be
2.24
Margin of error = ±Critical value*std deviation
= ±2.24(4)
= ±8.96
Confidence interval =(Mean - margin of error, mean + margin of error)
=
Okay so CBE is a right angle which equals 90 degrees. CBD and DBE makes up CBE which is 23 degrees is part of CBD. So subtract CBE from CBD to get DBE which is 67 degrees.
