Answer:
02 High Schools would be selected from the stratum with a percent-free-lunch value of 40 less than or equals x.
Step-by-step explanation:
As the sample size needed is 25 and total schools are 100 so this indicate 1 school in each 4 schools is to be selected. This is given as
![n=\frac{n_{total}}{n_{sample}}\\n=\frac{100}{25}\\n=4](https://tex.z-dn.net/?f=n%3D%5Cfrac%7Bn_%7Btotal%7D%7D%7Bn_%7Bsample%7D%7D%5C%5Cn%3D%5Cfrac%7B100%7D%7B25%7D%5C%5Cn%3D4)
Now as the schools with percent free lunch are 8 so now
![n=\frac{n_{total}}{n_{sample}}\\n=\frac{8}{2}\\n=2](https://tex.z-dn.net/?f=n%3D%5Cfrac%7Bn_%7Btotal%7D%7D%7Bn_%7Bsample%7D%7D%5C%5Cn%3D%5Cfrac%7B8%7D%7B2%7D%5C%5Cn%3D2)
So only 2 schools will be selected in this regard.
3tenths because 5tenths=50 And 2tenths=20 so if you do 50-20 you will get 30 or if u do 20+30 you will get 50 so either way is fine
Your original answer is correct.If you set up a ratio table, it works. For example:
So, they amount of money she's taxed on is $55. We get this by doing 175-20.
$55 is equal to 106% because 6% is tax
Now, you want to find just 100% which is the same as no tax. To get from 106 to 11, you divide by 1.06. So, you also divide 55 by 1.06 to get $51.89
She can't go over this because she won't have enough money.
So, the answer is x≤$51.89
Hope this helps!
