The sample % of these two populations would be 100/size (of student body at each school) x 100 so this would compare the two student bodies preferences for the particular type of candy bar. However, the actual % of the whole student body at each school would be a factor also. If the high school only had 200 students then this would be 50% representative but if the middle school had say 500 students this would only be 20% representative so this would have to be taken into account too. It might be more representative to have the same % of the student bodies respectively for the sample.
First, we combine the terms on the left side of the equation to simplify the equation. Then we divide both sides by -3. k then equals 1/3.
To check, we plug in our value for k into the original equation:
We found k to be 1/3, so for every instance of k, we plug in 1/3. To simplify, we combine the left side to get -1, and we combine the right side to get -1.
Since -1 = -1, our solution is correct.
Answer:
Step-by-step explanation:
First we derive y two times
Second we replace in the differential equation y' and y'':
grouping terms
The terms on the left side must be equal to the terms of the right side, so
From 1.
From 2.
From 3.

Answer:
134.04 inches³
Step-by-step explanation:
Use the cone volume formula: V = r²
Plug in the radius and height, then solve for the volume
V = r²
V = (4²)
V = (16)
V = 134.04
So, the volume of the hat is 134.04 inches³
