An insurance company looks at its auto insurance
customers and finds that (a) all insure at least one car, (b)
85% insure more than one car, (c) 23% insure a sports
car, and (d) 17% insure more than one car, including a
sports car. find the probability that a customer selected at
random insures exactly one car and it is not a sports car.

if he has no friends he cant give them out to his friends

step-by-step explanation:

no friends = cant give anything out

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
