**Answer:**

**No, the manager is not correct based on the 95% confidence interval.**

**Step-by-step explanation:**

We are given that the average daily revenue over the past five-week period has been $1,080 with a standard deviation of $260, i.e.; X bar = $1080 and s = $260 and sample size, n = 35 .

The Pivotal quantity for 95% confidence interval is given by;

~

where, X bar = sample mean = $1080

s = sample standard deviation = $260

n = sample size = 35 {five-week}

So, 95% confidence interval for average daily revenue, is given by;

P(-2.032 < < 2.032) = 0.95

P(-2.032 < < 2.032) = 0.95

P(-2.032 * < < 2.032 * ) = 0.95

P(X bar - 2.032 * < < X bar + 2.032 * ) = 0.95

95% confidence interval for = [ X bar - 2.032 * , X bar + 2.032 * ]

= [ 1080 - 2.032 * , 1080 + 2.032 * ]

= [ 990.70 , 1169.30 ]

*No, the manager is not correct based on the fact that the coffee and pastry strategy would lead to an average daily revenue of $1,200 because the calculate 95% confidence interval does not include value of $1200.*

Therefore, the store manager believe is not correct.

The 95% confidence interval for the store's average daily revenue is calculated to be approximately ($993.97, $1166.03). Since $1200 is outside this interval, the manager's belief that the coffee and pastry strategy will lead to an average daily revenue of $1200 is not backed by this confidence level.

In the field of statistics, a confidence interval (CI) is a type of interval estimate that is used to indicate the reliability of an estimate. The method for calculating a 95% confidence interval for the average daily revenue involves the sample mean, the standard deviation, and the z-score associated with a 95% confidence level, which is approximately 1.96. Let's use the provided data to calculate:

- Calculate the standard error by dividing the standard deviation by the square root of the sample size. Here, the standard deviation is $260, and the sample size is 5 weeks * 7 days/week = 35 days. So, the standard error is $260 / sqrt(35) = $43.89.
- Multiply the standard error by the z-score to get the margin of error. So, $43.89 * 1.96 = $86.03.
- Calculate the lower and upper bounds of the 95% confidence interval by subtracting and adding the margin of error from/to the sample mean. So, ($1080 - $86.03, $1080 + $86.03) = ($993.97, $1166.03).

The range of this **95% confidence interval** is from $993.97 to $1166.03. This means we are 95% confident that the true average daily revenue lies within this interval. Since $1200 lies outside this interval, the manager's belief is not supported by this **confidence interval**.

a= 6 2/3, b=7

Answer:

29/3

Step-by-step explanation:

A^2= 400/9

B^2= 49

C^2= 841/9

C= sqr(c^2) = 29/3 or 9 2/3

The hypotenuse would be 9 2/3

Using the Pythagorean Theorem you do

6 2/3 squared + 7 squared

93 4/9 then you find the square root

And it leaves you with

9 2/3

Using the Pythagorean Theorem you do

6 2/3 squared + 7 squared

93 4/9 then you find the square root

And it leaves you with

9 2/3

The **statement **that best describes adjacent angles is that adjacent **angles share** a side.

A vertex is where two **non parallel **lines meet.For example a triangle has **3 vertex**.We can also say that vertex is a point where two non parallel lines meet to **form **an angle.

According to the **given** question the best description of adjacent angle is that they share a **side**.

We can say that adjacent **angles **are those angles which are placed **next **to each other.

Adjacent angle also share a **common **vertex but they do not **overlap **each other.

**Answer:**

The correct answer to this would be **D, adjacent angles share a side.**

**Step-by-step explanation:**

Adjacent angles share a common side as well as a common vertex.

A $3.478

B. $3.792

C. $2,489

D. $2,256

**Answer:**

**Step-by-step explanation:**

Becuase he wanted more then 3000

The answer is A I took the test :)

**Answer:**

A, B, and D.

**Step-by-step explanation:**

HEY!! remember that if a number has ^2, it basically means it's multiplied by itself. for example:

5^2 = 5 x 5

aka, 25.

You can use this to check each of the answers in your formula, like this:

if x=6, then:

x^2 < 100

6 x 6 = 36

36 < 100

A is one of your correct answers!

Also remember, if you multiply a negative by a negative, it becomes positive.

-5 x -5 = 25

-10 x -10 = 100

The answer to this is A, B, D.
