Chapin manufacturing company operates 24 hours a day, five days a week. the workers rotate shifts each week. management is interested in whether there is a difference in the number of units produced when the employees work on various shifts. a sample of five workers is selected and their output recorded on each shift. at the 0.01 significance level, can we conclude there is a difference in the mean production rate by shift or by employee?

eve and marks ratios are equivalent

step-by-step explanation:

the workers who do no drive has no reasonable reason to buy gasoline due to they don't have anything to use it for

let's cover over the formula of the vertex:

y = a(x – h)^2 + k

in this formula, (h,k) are the vertex, always remember that the positive or negative value of the vertex is based on the sign it has.

for example, if the vertex is -3,-6 then both the x and y value would have the positive sign attached to it and if it were a positive x and y value, then a negative sign would be attached to it.

with that being said, for our problem the x value is a positive one so we are looking for a number with a negative sign next to it, in this case the first and second choice.

however, for the first answer choice it isn't quite part of the formula so we know that the answer choice correctly displays the x value.

to confirm, we can see if the -1 fits correctly with the second answer choice, and as mentioned above a negative number will have a positive sign attached to it. so, for our problem we can see that -1 has been changed to +1, so we can confirm that the second answer choice is correct.

hence, our final answer is y=(x - 1)^2 + 1

2,160 π
