All else being equal, if you cut the sample size in half, how does this affect the margin of error when using the sample to make a statistical inference about the mean of the normally distributed population from which it was drawn?

The margin of error is multiplied by V0.5

The margin of error is multiplied by 2

The margin of error is multiplied by 0.5.

The margin of error is multiplied by 2

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 "add 2y and y"

step-by-step explanation:

you need to collect the like terms first.

the first domain and range set to the left is matched with the top relation, and the second set the set in the middle goes with the bottom relation.
