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
Answer:
x=1
Step-by-step explanation:
You multiply the 1/2 by everything in the parentheses, but multiplying by 1/2 basically cuts everything in half. So you would have (3x+4)=2x+4+x
Add the like terms together, so 2x+x=3x
Now you have 3x+4=3x+4
Because they are the same, your answer is 1.
51sin(47) because 51 is the hypotenuse and a is the opposite so we use sine because sine=opp/hypotenuse therefore sin(47)=a/51 then rearrange the formula to make a the subject the final answer is 37.3 to the nearest 3 significant figures
5/1, 15/3, and 10/2 are all valid answers to that question.
Answer:
Hi, I'm unsure as to what digit you wanted us to round the answer to, so I rounded the answer to the 4 most commonly used decimal places.
First off, we figure out that <em>614 divided by 31 equals </em><em><u>19.8064516129.</u></em>
Rounded to the nearest thousandth, that's <u><em>19.806.</em></u>
Rounded to the nearest hundredth, that's <u><em>19.81.</em></u>
Rounded to the nearest tenth, that's <u><em>19.8.</em></u>
Rounded to the nearest whole number, that's <u><em>20.</em></u>
