Jillian wants to know what percent of students at her school watch sports on TV. Which strategy for sampling will be more likely to produce a representative sample?

At the next school assembly, ask every third student who enters whether or not they watch sports on TV

Step-by-step explanation:

Students at a football game may like watching sports more than students who don't go to football games.

If Jillian wants to know about the students at her school, she should sample in a way that gives every student at her school an equal chance of being in the sample.

The answer for a more representative sample:

At the next school assembly, ask every third student who enters whether or not they watch sports on TV.

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

answer: your answer is c
