Graph: a bell shape graph starting from 70 till 135the iq score that more people had than any other iq score, and which the scores fall off in a symmetrical manner as the deviation increases or decreases from is the iq score of 90

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

i think u have 12 apples sorry again i don't really know if it correct i'm just tryna hrlp people out.

the answer would be 0.54
