Answer:
$588.
Step-by-step explanation:
You take $28,000 divide it by 100. Because you put your 2.1% above the 100 and x above the 28,000, you then cross multiply. Usually the teacher always called it butterfly method.
Hope this helps
Answer:
50% change in volume
Step-by-step explanation:
<h2>
This problem bothers on the mensuration of solid shapes.</h2>
In this problem we are to find the volume of the first cylinder and compare with the second cylinder.
Given data
Volume v = ?
Diameter d=
?
Radius r = 
Height h= 
we know that the volume of a cylinder is expressed as

Substituting our given data we have

The first cylinder as a volume of 
The change in volume is 
percentage = 

%
I hope it's not to late but the answer would be 81
Answer:
(0.102, -0.062)
Step-by-step explanation:
sample size in 2018 = n1 = 216
sample size in 2017 = n2 = 200
number of people who went for another degree in 2018 = x1 = 54
number of people who went for another degree in 2017 = x2 = 46
p1 = x1/n1 = 0.25
p2 = x2/n2 = 0.23
At 95% confidence level, z critical = 1.96
now we have to solve for the confidence interval =
<h2>

</h2>

= 0.02 ± 1.96 * 0.042
= 0.02 + 0.082 = <u>0.102</u>
= 0.02 - 0.082 = <u>-0.062</u>
<u>There is 95% confidence that there is a difference that lies between - 0.062 and 0.102 on the proportion of students who continued their education in the years, 2017 and 2018.</u>
<u></u>
<u>There is no significant difference between the two.</u>
It doesn't matter. It can't be correct either way.
The range says that 'x' is a number between 90 and 180.
Neither -0.6 nor +0.6 is between 90 and 180.
