The time that it takes for the next train to come follows a Uniform distribution with f(x) =1/50 where x goes between 5 and 55 minutes. Round answers to 4 decimal places when possible.

(3x-8) or (3x+8)

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
