Suppose you conduct an experiment in which you draw a single card from a standard deck of 52 cards. Which events are mutually exclusive? Select all that apply. choosing a card that is an ace and a four
choosing a card that is a diamond and a king
choosing a card that is a king and a heart
choosing a card that is a king and a queen
choosing a card that is a heart and an odd number

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

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
