Let's figure this out as though we have no idea what the answer would be.
Step One
Find the new five numbers.
3*3, 8*3, 12*3, 17*3, 25*3
9 , 24 , 36, 51, 75
Step 2
Find the average
(9 + 24 + 36 + 51 + 75)/5 = 195/5 = 39
Step 3
Subtract the individual numbers from the average
(39 - 9) = 30
(39 -24) = 15
(39 - 36) = 3
(39 - 51) = - 12
(39 - 75) = -36
Step 4
Square the results from Step 3
30^2 = 900
15^2 = 225
3^2 = 9
(-12)^2 = 144
(-36)^2 = 1296
Step 5
Take the average of the results from step 4
(900 + 225 + 9 + 144 + 1296)/5
2574 / 5 = 514.8
Step 6
Take the square root of the result from step 5
deviation = sqrt(514.8)
deviation = 22.689
Step seven
Compare the two standard deviations.
s2/s1 = 22.689 / 7.563 = 3
Conclusion
If you are given 1 set of numbers to find a population standard deviation and you multiply each member by a, then the result will be a * the standard population deviation of the first set of numbers.
Note
Your calculator will do this as well, but you have to know how to enter the data into your calculator. That requires that you follow the directions carefully.
Answer:
x = 10
Step-by-step explanation:
Since both equations give y in terms of x, equate the right sides
3x - 28 = - 2x + 22 ( add 2x to both sides )
5x - 28 = 22 ( add 28 to both sides )
5x = 50 ( divide both sides by 5 )
x = 10
The area of a parallelogram is
![A=bh](https://tex.z-dn.net/?f=A%3Dbh)
![A=10(18.5) \\ A=185](https://tex.z-dn.net/?f=A%3D10%2818.5%29%20%5C%5C%20A%3D185)
I am assuming you're asking for the entire parking lot, so you would have to multiply the above area by 916
![185(916) = 169,460 ft^{2}](https://tex.z-dn.net/?f=185%28916%29%20%3D%20169%2C460%20%20ft%5E%7B2%7D%20)
So the answer is (D)

Answer:
$333.33
Step-by-step explanation:
This question is a little bit confusing, but I am assuming you mean to say that the 72% of the total pay, which is the amount he took home, is $240. So, then you can set up a proportion to solve the problem.
72![\frac{72}{100} = \frac{240}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B72%7D%7B100%7D%20%3D%20%5Cfrac%7B240%7D%7Bx%7D)
Then, you multiply the proportion out, getting ![72x = 240*100](https://tex.z-dn.net/?f=72x%20%3D%20240%2A100)
multiply the right side out and then divide by 72 to get $333.33
