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
Now as the schools with percent free lunch are 8 so now
So only 2 schools will be selected in this regard.
1. 16
2. 11

Answer:
A food company is designing boxes for several products. Each box is a rectangular prism.
The food company is now designing soup boxes. The largest box of soup will be a dilation of the smallest box using a scale factor of 2. The smallest box must hold 8 fluid Ounces or about 15 cubic
inches of soup. Find a set of dimensions for the largest box
Step-by-step explanation:
The solution would be like this for this specific problem:
Volume of a cylinder = pi * r^2 * h
Volume of a cone = 1/3 * pi * r^2 * h
Total Height = 47
Height of the cone = 12
Height of the cylinder = 35
If the top half is filled with sand, then:
volume (sand) = pi * 4^2 * 36
volume (cone) = 1/3 * pi * 4^2 * 12
Total volume = 1960.353816 cubic millimeters
353816 / (10 * pi) = 62.4 seconds.
It will take 62.4 seconds until all of the sand has dripped to the bottom of the hourglass.
