Answer:
Do you have a pic of the problem?
Step-by-step explanation:
Only then, can i really edit this and provide an acurate answer...
pls & thx.
The
formula for the population proportion is:
n = p ± Zc 
where p =
confidence level = 0.2
n =
proportion = 0.22
= standard error = 0.01
Finding for Zc:
.20+(.01)=.22
Zc = 2
Referring to Critical value table for standard
normal curve, a Zc value of 2 is equivalent to 95% Confidence Level.
Answer: 95% Confidence Level
Answers:
choice A) y = 0x
choice D) y = 0/x
========================================================
Explanation:
Choice A is the same as y = 0 because 0x turns into 0. Multiplying 0 with any number always leads to 0.
Similarly, choice D is the same as y = 0 as well. Dividing 0 over any nonzero value leads to 0. Note the key term "nonzero" here. We cannot have 0 in the denominator. So x = 0 is not allowed for choice D.
So for any nonzero x, we have 0x and 0/x result in the same thing.

Extra info:
Choice B can be ruled out because something like x = 2 leads to y = 2.
Choice C is ruled out because we can never have 0 in the denominator.
Answer:
The answer is QR,RS, and ST
Step-by-step explanation:
i hope this helps .
Given:
25.7 kwh of electricity per day.
must reduce 20%
25.7 kwh * 20% = 5.14 kwh * amount of electricity to be reduced.
25.7 kwh - 5.14 kwh = 20.56 kwh * net of reduced electricity
The homeowner will use 20.56 kwh after reduction of 20%.
