What is the complement of April choosing five pop CDs

first what so crazy is we are on the same site edunity

for online school crazy right

the complement of an event is everything possible except that event.  It is found by subtracting the probability of an event from 1.

The event we have listed is April choosing 5 pop CDs.  The complement would literally be read as "not choosing 5 pop CDs."  This means she would choose 5 CDs, where some could possibly be pop, but others would not.

Step-by-step explanation:

true? is that what you're asking or do you mean something else?

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
