Mr. blackwells's class is conducting an experiment to find the probability of pulling certain colors from a bag of 25 marbles. if 2 are
purple, 7 are yellow, 2 are green, and the rest are black, what is the probability of drawing a purple and yellow if the marbles are not
replaced after they are picked?

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
