Answer:
900
Step-by-step explanation:
We have, 4% × x = 36
4
or ----- × x = 36
100
Multiplying both sides by 100 and dividing both sides by 4,
100
we have x = 36 × -------
4
x = 900
If you are using a calculator, simply enter 36×100÷4, which will give you the answer
Answer:
The first one
Step-by-step explanation:
In this question, we are trying to find X, so can solve this by back-solving. multiply the choices by the A until they equal B. If you do it for the first one then you should gett B.
Yes, because GCF is the greatest common factor
Answer:
what are we supposed to answer? im confused.. i can help i just dont know what to answer
Step-by-step explanation:
Given:
Population proportion,

= 57% = 0.57
Population standard deviation, σ = 3.5% = 0.035
Sample size, n = 40
Confidence level = 95%
The standard error is

The confidence interval is

where

= sample proportion
z* = 1.96 at the 95% confidence lvvel
The sample proportion lies in the interval
(0.57-1.96*0.0783, 0.57+1.96*0.0783) = (0.4165, 0.7235)
Answer: Between 0.417 and 72.4), or between (41% and 72%)
