Marcus is choosing 4 books to read from a list of 15 books. If order matters, how many ways can he choose to read the books?


4

32,760

23,760

60

Answers

Answer 1

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

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​

Answers

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

Answers

8.75 hope this helps

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

What is the mean absolute deviation (MAD)?

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.

A king bed measures 76 inches wide by 80 inches long. How much does the length exceed the width?
A) 4 inches
B) 7 inches
C) 11 inches
D) 14 inches

Answers

Answer:

A) 4 inches

Step-by-step explanation:

The length is 80 inches and the width is 76 inches. To find the difference subtract 80 minus 76 and you get 4... the amount that is exceeding the width!

Have a wonderful day!

Answer:

A. 4 inches

Step-by-step explanation:

In order to find by how much the length exceeds the width we have to subtract width from the length in order to get the difference between the two lengths, and so we get...

80 - 76 = 4

Therefore the answer is A. 4 inches

I am very confused- Can someone help within an hour-

Answers

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

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

Answers

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.

What is histogram?

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: number greater than -8 includes -2, 1/4, 2.6, 4

Explanation:


Answer:

Answers = a , c, d, e

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.

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

Answers

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.

What is volume?

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.
