What is the shape of the following distribution {9, 10,10,11,11,12,12,13,13,13,14,14,14 ,14,15,15,15,15,16,16,16,16,17,17,1 7,17,18,19,20}

A: negative skew
B: positive skew
C: symmetric
D: asymmetric with no skew
E: none of the above

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

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

answer: what are the following choices
