32,760

23,760

60

Answer:

32,760

Step-by-step explanation:

Given :

Since the order matters, we use the permutation relation :

Recall :

nPr = n! ÷ (n - r)!

n = 15 ; r = 4

15P4 = 15! ÷ (15 - 4)!

15P4 = 15! ÷ 11!

15P4 = (15 * 14 * 13 * 12)

15P4 = 32,760

Find the volume and surface area of the composite figure shown below if the figure is built with unit cubes.

**Answer:**

the volume is 18 and the surface area is 46

**Step-by-step explanation:**

The **volume **of the **cube **will be and the **surface **area of the **cube **will be **square **units.

Volume is **defined **as the space **covered **by any solid body in the **three**-**dimensional **plane. The volume of the **cube **will be calculated by multiplying all **three **sides of the **cube**.

The **volume **will be **calculated **as below:-

The **formula **to **calculate **the volume = l x w x h

The **volume **of the **first **part = 2 x 2 x 3 = 12 cubic units

The **volume **of the **Second **part = 2 x 2 x 1 = 4 cubic units

The **volume **of the **third **part = 2 x 1 x 1 = 2

Total **volume **of the cube = 12 + 4 + 2 = **18 **cubic units.

The **space **occupied by any two-**dimensional **figure in a plane is called the area. The **area **of the outer surface of any **body **is called the **surface **area.

The **surface **area will be **calculated **as below:-

**Surface **area of the **base **= 2 ( 4 x 2) + 2( 2x 1) + 2 ( 4x 1) = 28

**Surface **area of the **middle **= 2 ( 3 x 2 ) + 2 ( 2 x 1 ) + 2 ( 3 x 1) = 22

**Surface **area of the **upper **side = 2 ( 2 x 2) +2 ( 1 x 2 ) + 2 ( 1 x 2) = 16

The **total **surface **area **is **calculated **as below:-

Total = 28 + 22 + 16 = **66 square units.**

Which of the following pairs of events are disjoint (mutually exclusive)?

a) A: odd numbers; B: the number 5

b) A: even numbers; B: numbers greater than 10

c)A: numbers less than 5; B: all negative numbers

d)A: numbers above 100; B: numbers less than -200

**Answer:**

d

**Step-by-step explanation:**

d because there are no numbers common to both sets

**Disjoint** sets are those **sets** that have **no** **common** **values** between the sets.

A: numbers **above** 100; B: numbers **less** than -200 is a **disjoint** set.

Option D is the correct answer.

What is a set?A set is a collection of items where there are operations such as:

Union of sets, the intersection of sets, complements of sets.

We have,

**Disjoint** **sets** are those **sets** that have **no** **common** values between the sets.

a) A: **odd** **numbers**; B: the **number** 5

Set A = {1, 3, 5, 7, 9,.....}

Set B = {5}

A ∩ B = {5}

This is **not** a **disjoint** set.

b) A: **even** **numbers**; B: numbers **greater** than 10

A = {2, 4, 6, 8, 10, , , }

B = {11, 12, 13, 14, 15, 16, 18,,,,,}

A ∩ B = {12, 14, 16, 18,,,}

This is **not** a **disjoint** set.

c) A: numbers **less** than 5; B: all **negative** numbers

A = {, , ,, -3, -2, -1, 0, 1, 2, 3, 4}

B = {, , , , -3, -2, -1}

A ∩ B = { , , , , -3, -2, -1}

This is **not** a **disjoint** set.

d) A: numbers **above** 100; B: numbers **less** than -200

A = {101, 102, 103, 104, ,,,,,,}

B = {, , , , -204, -203, -202, -201}

A ∩ B = Ф

There are no **common** **values** between set A and set B.

This is a **disjoint** set.

Thus,

A: numbers **above** 100; B: numbers **less** than -200 is a **disjoint** set.

Option D is the correct answer.

The mean absolute deviation is 46,54,43,57,50,62,78,42

8.75 hope this helps

The **mean absolute deviation** (MAD) of the given set of numbers is 8.75.

The mean absolute deviation (MAD) of a group of data points is a **statistical **metric used to evaluate its dispersion or **variability**. It indicates how far off the data values are from the mean (average) of the data collection.

Let's calculate the **MAD **for the given set of numbers: 46, 54, 43, 57, 50, 62, 78, 42.

Calculate the **mean**:

Mean = (46 + 54 + 43 + 57 + 50 + 62 + 78 + 42) / 8 = 432 / 8 = 54

Find the **absolute **difference between each number and the mean:

|46 - 54| = 8

|54 - 54| = 0

|43 - 54| = 11

|57 - 54| = 3

|50 - 54| = 4

|62 - 54| = 8

|78 - 54| = 24

|42 - 54| = 12

Calculate the **average **of these absolute differences:

MAD = (8 + 0 + 11 + 3 + 4 + 8 + 24 + 12) / 8 = 70 / 8 = 8.75

Therefore, the mean absolute deviation (MAD) of the given set of numbers is 8.75.

Here is the histogram of a data distribution.

What is the shape of this distribution?

A. Bimodal symmetric

B. Uniform

c. Unimodal symmetric

D. Bimodal skewed

E. Unimodal skewed

**Answer:**

Uniform

**Step-by-step explanation:**

We don't have any peaks in the histogram, so its neither unimodal or bimodal leaving only uniform as the answer.

The shape of this **distribution**, histogram is Unimodal **skewed type**. The correct option is E.

A **histogram **represents the graphical representation of the distribution of data. The histogram is indicated by using a set of rectangles adjacent to each other where each bar represent a kind of data. The histogram doesn't involve any gaps between the two successive bars.

The histogram would be classified into different types based on the **frequency distribution** of the data.

Based on the direction of the tail, the skewed distribution may be either right-skewed or left skewed.

Since **skewed** **distribution **is asymmetrical as a limit which is natural resists end results on one side.

Threfore, the correct option is E.

Answer: 195 CM

Step-by-step explanation:

Volume: Length x Width x Height

“First we have to break it into 2 shapes”

“Let’s solve the top shape!!”

The length is 5 the width is 3 and the height is 4.

Volume = 5 x 3 x 4 = 60

Now the bottom shape

The length is 9 the Width is 5 and the Height is 3

The height isn’t given so we must do some math

Subtract the 7 from 4 = 7 - 4 = 3

Volume = 9 x 5 x 3 = 135

Finally, 135 + 60 = 195 cm

Step-by-step explanation:

Volume: Length x Width x Height

“First we have to break it into 2 shapes”

“Let’s solve the top shape!!”

The length is 5 the width is 3 and the height is 4.

Volume = 5 x 3 x 4 = 60

Now the bottom shape

The length is 9 the Width is 5 and the Height is 3

The height isn’t given so we must do some math

Subtract the 7 from 4 = 7 - 4 = 3

**Step-by-step explanation:**

Absolute value of -8 = 8

Find the absolute values of the other numbers

The other numbers have to be less than 8 or else they are less than -8

Absolute value of 2.6 = 2.6 . 2.6<8

Absolute value of -10 = 10 . 10 >8 . not correct

Absolute value of -2 = 2 . 2<8

Absolute value of 4 = 4 . 4<8

Absolute value of 1/4 = 1/4 . 1/4<8

Absolute value of -8.5 = 8.5 . 8.5>8 . not correct

About Absolute Value:

Absolute value is the distance from 0 on the number line.

The number 5 is 5 units from 0

The number -5 is also 5 units from the 0, except from the opposite side

Absolute value states that negative numbers have a positive absolute value and a positive number has a positive absolute value.
