The scores on a test given to all juniors in a school district are normally distributed with a mean of 80 and a standard deviation of 7. Find the percent of juniors whose score is no more than 94.

The percent of juniors whose score is 94 or below is
%.

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

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60
