Suppose that a company claims that its coffee cans contain 6.8 ounces of
coffee, on average. you take many large samples, and find, each time, that
the mean weight of the sample is within the 95% confidence interval. which of
the following would be a reasonable conclusion?
o
a. the company's coffee cans contain more than 6.8 ounces of
coffee, on average
b. the company's coffee cans contain 6.8 ounces of coffee, on
average
o
c. the company's coffee cans contain less than 6.8 ounces of
coffee, on average
o
d. the company's coffee cans do not contain 6.8 ounces of coffee,
on average

step-by-step explanation:

i got 10.28 but that rounds up to 10.3

answer: 12

step-by-step explanation:

because yes

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
