How can a sample data be used to form an estimate about the population? Use the drop down menus to explain your answer. A(n) (Proportion, range, expression) can be written to relate the sample to the (random group, population, mean) and solved to form an estimate.

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
