It pretty easy I am just not thinking straight! Please help! No files or links, I will report them! Question: Josie thinks that because she has two pets, that the average number of pets each of her classmates has is also two. Is this a good statistical description of the number of pets each student has? What should she do instead?

answer: t=3

step-by-step explanation:

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
