What is the probability that between 970 and 990 of these intervals contain the corresponding value of μ? [hint: let y = the number among the 1000 intervals that contain μ. what kind of random variable is y? ] (round your answer to four decimal places.)

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.

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

answer: (-6,3)
