Which is most likely the correlation coefficient for the set of data shown

-0.65

-0.19

0.19

0.75

false

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

the answer is b

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
