Answer:

7.2 | 6.2 | 2.2 | -2.8 | -3.8 | -8.8

0.2

Step-by-step explanation:


Step 1) Find the mean

How to find it?

Add all the numbers listed above and divide by the number of numbers in the set (6)

This mean you should get 67/6=11.2


Step 2) Find the distance from the mean.


How do I do this?

Since you are trying to find the difference you will use the equation 11.2-(number)

Example) 11.2-4=7.2

This will give you the answers for the second half of the table.


Step 3) Find the mean of those distances to find the mean absolute deviation


How do I do this?

Add all the numbers on the second half of the table and then divide by 6. This will give you your mean absolute deviation.

The profit (p) a baker earned, in dollars, is proportional to the number of muffins (m) sold. this equation represents this relationship.
P = 0.75m
enter the profit earned for each muffin sold.

Answers

Answer:

The profit is $0.75 per muffin.

Step-by-step explanation:

If P = .75m, then if m is 0, then P is zero (if the baker sells no muffins, they make no money)

If m = 1 (sold 1 muffin)

then P = .75, they made 75cents.

"for each muffin sold" means for 1 muffin.

Answers

Answer: Answer:

There is moderate level of overlap between the two data sets.  

Step-by-step explanation:

Overlap of data sets.

Overlap measures the degree of duplication that exists within data sets.

It is an indicator of the degree to which data are identical.

We are given two data sets in the question.

We have to find the amount of overlap in data set 1 and in data set 2.

There are 8 data points in data set 1 as shown in the image.

There are 8 data points in the data set 2 as shown in the image.

Out of the 8 data points for both data set 1 and data set 2, 5 data points overlap each other on 6, 7, 8 and 9.

Thus, we could say there is moderate level of overlap between the two data sets.

I'd also appreciate anyone who can help me, as I am in need of it.

Thank you.

Answers

Area of a circle:
(pi)r^2
(pi)r^2 = (pi) 81
r^2 = 81
r = 9

Perimeter of a circle:
2(pi)r
[2(pi)9]:3 = (18pi):3 = 6pi [the two small arcs]

9 = 2.87pi

2.87pi x 4 = 11.5pi

Perimeter of shaded area:

Which two expressions are equivalent?

Answers

Answer:

F

Step-by-step explanation:

Each of these answer choices represents a different property of equality; however, only answer choice F uses the properties of equality (PoEs) correctly.

Answer Choice F

The first answer choice shows the distributive property. This property states that multiplying a number by a factor in parentheses is the same as multiplying the number outside the parentheses by each of the terms within the parentheses.

For example, [tex]5(x-y)=5x-5y[/tex].

Answer Choice G

This answer choice attempts to show the associative property. The associative property states that when doing addition, the placement of the parentheses does not matter. However, this answer uses addition and multiplication, so the associative property does not apply.

Answer Choice H

This answer choice tries to show the commutative property. The commutative property states that addition and multiplication can be done in andy order. However, this only applies to addition and multiplication. So, it cannot be used for division.

Answer Choice J

This answer choice tries to use the associative property similar to the second answer. However, as I stated earlier, this property only works for addition. So, the use of multiplication in the expression makes it so they are not equal.

Answer:

F is your answer

Step-by-step explanation:

Answer Choice F

The first answer choice shows the distributive property. This property states that multiplying a number by a factor in parentheses is the same as multiplying the number outside the parentheses by each of the terms within the parentheses.

Answer:

Option C, 488 square centimeters

Step-by-step explanation:

Step 1:  Determine the area of the rectangle

[tex]A = l * w[/tex]
