Hi!
<h3>Let's set up a proportion and cross multiply to solve. </h3>2 * 12 = 24
24/3 = 8
<u></u>
<em>(l = length</em>
<em>w = width </em>
<em>p = perimeter)</em>
l + l + w + w = p
<u>12 + 12 + 8 + 8 = 40</u>
<h2>The perimeter of the floor is 40 meters. </h2>Hope this helps! :)

Answer:
The required sample size for the new study is 801.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
The margin of error is:
25% of all adults had used the Internet for such a purpose
This means that
95% confidence level
So , z is the value of Z that has a pvalue of
, so
.
What is the required sample size for the new study?
This is n for which M = 0.03. So
Rounding up:
The required sample size for the new study is 801.
Answer:
<h2>Step-by-step explanation:
To find f(−1) , substitute the values of x that's - 1 into f(x). That is for every x in f(x) replace it with - 1
That's
