There are 96 dogs at the dog park.
1/8 of the dogs are brown
5/6 of the dogs are black.
The rest are mixed colors.
In this park how many dogs are mixed colors?

Answers

Answer:

4 dogs :]

Step-by-step explanation:

1/8 brown dogs = 12 dogs

5/6 black dogs = 80 dogs

12 + 80 = 92

96 - 92 = 4

Therefore, 4 dogs are mixed colors.

Hope this helps, sorry if this is wrong! Have a great day! <)

Answer:

4 dogs.

Step-by-step explanation:

To solve this, we can find 1/8 of the dogs and 5/6 of the dogs then add them together. (This is the total amount of brown and black dogs.) Then, we can subtract this number from 96 (total) to find the rest (mixed colors).

1/8 of 96 is 12. There are 12 brown dogs.

5/6 of 96= 96/6*5= 80. There are 80 black dogs.

80+12=92.

Subtract that from 96 and you get 4—the number of dogs with mixed colors.

4 dogs are mixed colors.

A teacher surveyed her class after they had taken a vocabulary test. Eighteen of the students claimed they had studied at least one hour for the test. The remaining twelve students admitted that they had not studied for the test at all. The test results (expressed as a percent) for the two groups are shown below.

Studied: 87, 100, 94, 79, 92, 100, 95, 83, 89, 99, 100, 91, 89, 95, 100, 93, 96, 83

Did Not Study: 82, 72, 45, 91, 58, 83, 65, 87, 90, 77, 73, 89

Part 1: Calculate the mean of the group that did not study, rounded to the nearest tenth.

Part 2: Calculate the mean absolute deviation of the group that did not study, rounded to the nearest tenth.

Part 3: How many of the scores (from the group that did not study) are more than two mean absolute deviations from the mean?

Answers

Answer:

92.5

Step-by-step explanation:

1 is actually the mean of the group that did study is 92.5

2 is the MAD 5.2.

3is there are ten scores that are within the one MAD of the mean.

The answer would be 92.5

Look at the composite figure below. The rectangle is 15 inches by 7 inches. The two congurent
squares have a side length of 5 inches.
What is the shaded area of the composite figure in square inches?

Answers

Answer: 80 square inches

Step-by-step explanation:

The rectangle’s area is 105 square inches

Each square had an area of 25 square inches, divide 25 by two to get both triangles (12.5)

Multiply by two (gets 25)

Subtract that from 105 and you get 25

Answer:

80 squared inches

Step-by-step explanation:

you find the area of the rectangle first which is 105

then you take away half of each square from the rectangle for each side so just picture the squares as triangles

base=5in          so now you find the area of each triangle which gives you  

height=5in             5 * 5 / 2= 12.5   and since you have two,multiply 12.5 by 2

12.5 *2 = 25  

 now subtract 25 from 105 (105 - 25= 80)

and you get your area =80 sq. in.

Write a polynomial in standard form that represents the area of the shaded region.


A rectangle. Its length is labeled 2 x minus 9 and its width is labeled x plus 5.

Answers

Answer:

2x²+x-45

Step-by-step explanation:

In standard form the area of the rectangle is -

A = (2x² + x - 45) square units.

What is function?

A function is a relation between a dependent and independent variable. We can write the examples of functions as -

y = f(x) = ax + b

y = f(x, y, z) = ax + by + cz

Given is to write a polynomial in standard form that represents the area of the shaded region which is rectangle whose length is labeled (2x - 9) and its width is labeled (x + 5).

We can write the area of the rectangle as -

A = (2x - 9)(x + 5)

A = 2x(x + 5) - 9(x + 5)

A = 2x² + 10x - 9x - 45

A = 2x² + x - 45

Therefore, in standard form the area of the rectangle is -

A = (2x² + x - 45) square units.
