First to find the area of briins pantry we divide 81 square feet with 9 so we get 9 square feet as the area of brinns pantry. And the since Area = length × width , so length will be Area/ width so 9 square feet divided by 3 feet equals 3 feet. Length = 3 feet

The average spending at Neco's salad bar is $9.03 with a standard deviation of $3.26. The distribution follows t-distribution. T
arlik [135]

Answer:

The difference between these cut-offs is of $1.9.

Step-by-step explanation:

In this question, we have to find the 90% confidence interval, using the t-distribution.

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 41 - 1 = 40

90% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 40 degrees of freedom(y-axis) and a confidence level of 1 - \frac{1 - 0.9}{2} = 0.95. So we have T = 1.684

The margin of error is:

M = T\frac{s}{\sqrt{n}} = 1.684\frac{3.26}{\sqrt{41}} = 0.95

In which s is the standard deviation of the sample and n is the size of the sample.

The lower end of the interval is the sample mean subtracted by M. So it is 9.03 - 0.95 = $8.08.

The upper end of the interval is the sample mean added to M. So it is 9.03 + 0.95 = $9.98.

What will be the difference between the upper and lower spending cut-offs which define the middle 90% of the customers if the sample contains 41 customers

$9.98 - $8.08 = $1.9

The difference between these cut-offs is of $1.9.

In which set of ordered pairs, (x, y), is y not a function of x?
3241004551 [841]

For y to not be a function of x, there needs to be an x-value that is paired with more than one y-value.

In terms of the sets, you need to find a set where the same x-value is used more than once in two (or more) different (x,y) pairs.

This occurs in the third set, where x=6 is used twice.

Uwu this isnt a test but its practiceee
igor_vitrenko [27]

<u>Answer</u>: B, (-3/2, -1)


<u>Step-by-step explanation:</u>

When you use the midpoint formula, (x1+x2/2 , y1+y2/2) you end up taking one away from -4, and dividing it by 2 (-3/2), and when you add 2 to -4, you get -2, divided by 2, is -1.
