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

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.

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.
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.

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.
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.

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
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
