Can anyone help me with this geometry test please I will give brainlist!!

The distribution of annual profit at a chain of stores was approximately normal with mean \mu = \$66{,}000μ=$66,000mu, equals, d

Pepsi [2]

Answer:

The closest to the maximum profit is $x = \$ 83682$

Step-by-step explanation:

From the question we are told that

The mean is $\mu = \$66,000$

The standard deviation is $\sigma = \$ 21000$

The percentage of profit is 20%

Generally the closest to the maximum annual profit at a store where the executives conducted an audit is mathematically evaluated as follows

$P(X > x ) = 0.20$

=> $P(X > x ) = P(\frac{X -x}{\sigma } > \frac{x -66000}{21000} ) = 0.20$

From the z-table the z-score for 0.20 is

$z-score = 0.842$

So

$\frac{x -66000}{21000} = 0.842$

=> $x = \$ 83682$

Explain the difference between using the sine ratio to solve for a missing angle in a right triangle versus using the cosecant r

oksano4ka [1.4K]

Answer:

The sine ratio is the ratio between the opposite side over hypotenuse. The cosecant ratio is the ratio between the hypotenuse over the opposite side, therefore cosecant is the reciprocal of sine.

To find a missing angle using sine, you would need to use the inverse of sine. For example, if the sine was $\frac{30}{40}$ , to find the angle you would need to find sin⁻¹ of $\frac{30}{40}$ which is x = sin⁻¹ (0.75). Therefore x equals approximately 49°.

Customers at your store select their groceries from shelves and then pay. Sales records and records of restocks for Flaming Roas

ioda

Answer:

The net change in how many bags are on the shelf, from the beginning of Tuesday to the end of Monday is -2.

Explanation:

The change in the number of bags any day is the number of bags is equal to the number of bags purchased to restock less the number of bags sold that day.

Change = bags purchased to restock - bags sold

At the end of Tuesday, the change is:

Restock: 6

Sales: 5

Change: 6 - 5 = 1 (note that this means that the number of bags increases by 1)

At the end of Wednesday, the change is:

Restock: 12

Sales: 8

Change: 12 - 8 = 4 (the number of bags increases by 4)

At the end of Thursday, the change is:

Restock: 12

Sales: 2

Change: 12 - 2 = 10 (the number of bags increases by 10)

At the end of Friday, the change is:

Restock: 18

Sales: 19

Change: 18 - 19 = - 1 (the number of bags decreases by 1).

At the end of Saturday, the change is:

Restock: 24

Sales: 22

Change: 24 - 22 = 2 (the number of bags increases by 2).

At the end of Sunday, the change is:

Restock: 0

Sales: 15

Change: 0 - 15 = - 15 (the number of bags decreases by 15).

At the end of Monday, the change is:

Restock: 0

Sales: 3

Change: 0 - 3 = - 3 (the number of bags decreases by 3).

The net change in how many bags are on the shelf, from the beginning of Tuesday to the end of Monday equals the algebraic sum of every change:

Net change = 1 + 4 + 10 + (-1) + 2 + (-15) + (-3)

Using associative property: (1 + 4 + 10 + 2) - (1 + 15 +3)

Simplifying: 17 - 19 = -2

Conclusion: the net change in how many bags are on the shelf, from the beginning of Tuesday to the end of Monday is -2, meaning that the number of bags, after taking into account all sales and restock, decreases by 2.

Find the volume (in cubic yards) of a cylinder with radius 1.2 yards and height 2.6 yards. (Round your answer to one decimal pla

ANEK [815]

Answer: 11.76

Step-by-step explanation:

The formula for cylinder is pi*r^2*h

so substitute and you will get pi*1.44*2.6

Simplify it and you will get 11.75616 or 11.76.
