The physical plant at the main campus of a large state university recieves daily requests to replace
florecent lightbulbs. The distribution of the number of daily requests is bell-shaped and has a mean of 41
and a standard deviation of 6. Using the empirical rule (as presented in the book), what is the approximate
percentage of lightbulb replacement requests numbering between 41 and 597
Do not enter the percent symbol.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75

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
