The mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.
What is mean absolute deviation?It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have data as shown in the picture in the form of frequency graph.
The mean = 11/4 = 2.75
The difference between each value and mean is shown in the attached table.
MAD = 5/4 = 1.25
The nearest value is 1.1.
Thus, the mean absolute deviation of this data set is 1.25 which is nearest to the 1.1 option third is correct.

Find the perimeter and the area of the polygon with the given vertices.
A (12,2), B (12,13), C (15,13), D (15,2)
The perimeter is __ units.
The area is __ square units.
Answers
Answer:
Step-by-step explanation:
As points A and B have same x-coordinate, length of AB will be given by the difference of y-coordinate
AB = 13 - 2 = 11 units
As points C and D have same x-coordinate, length of CD will be given by the difference of y-coordinate
CD = 13 - 2 = 11 units
As points B and C have same y-coordinate, length of BC will be given by the difference of x-coordinate
BC = 15 - 12 = 3 units
As points A and D have same y-coordinate, length of AD will be given by the difference of x-coordinate
AD = 15- 12 = 3 units
AB = CD = 11 units
BC = AD = 3 units
So,ABCD is a rectangle
Area = 11 * 3 = 33 square units
Perimeter = 11+11+3+3 = 28 units
Answer:
Solution :-At first
Length of AB = 13 - 2 = 11 cm
Length of CD = 13 - 2 = 11 cm
Length of BC = 15 - 12 = 3 cm
Length of AD = 15 - 12 = 3 cm
Now
Perimeter = 11 + 11 + 3 + 3
Perimeter = 22 + 6
Perimeter = 28
Area = 11 × 33 = 33 cm

Find the value of x - this is circle segments.
Answers
Given:
Diagram of a circle and its two secant from an exterior point.
To find:
The value of x.
Solution:
We know that, If two secant are on a circle from an exterior point, then the products of measure of secants and measure of external segments of secants are equal.
Using the above property, we get
[tex](x+7)x=(2+2)2[/tex]
[tex]x^2+7x=(4)2[/tex]
[tex]x^2+7x=8[/tex]
[tex]x^2+7x-8=0[/tex]
Splitting the middle term, we get
[tex]x^2+8x-x-8=0[/tex]
[tex]x(x+8)-1(x+8)=0[/tex]
[tex](x+8)(x-1)=0[/tex]
Using zero product property, we get
[tex](x+8)=0[/tex] and [tex](x-1)=0[/tex]
[tex]x=-8[/tex] and [tex]x=1[/tex]
Side cannot be negative.
Therefore, the only possible value of x is 1.

The equivalent expression to 3(x+ 1) is (3x+3).
What is Expression?An expression is a grouping of terms that have been joined together using mathematical operations such as subtraction, addition, multiplication, and division. In mathematics, the terms involved in an expression are:
A constant is an unchanging numerical value.Variable: A variable is a symbol with no fixed value.A term might be a single constant, a single variable, or a combination of a variable and a constant multiplied or divided.A coefficient is a number in an equation that is multiplied by a variable.We have the Expression 3(x+1)
Now, using the Distributive Property
a x ( b + c) = a x b + a x c
So, 3(x+1)
= 3(x) + 3(1)
= 3x+ 3
So, the equivalent expression is (3x+3).

You roll a die and flip a coin. What is the probability of NOT rolling a 4 on the die and flipping a heads on the coin?
Answers
Answer:
The probability of not rolling a 4 on the die and flipping heads on the coin is 5/6.
Step-by-step explanation:
Assuming the die is 6-sided, the probability of not rolling a 4 is 5/6, because all other possible values other than 4 can be rolled to make the probability true. 5/6
The probability of flipping heads on the coin is 1/2, considering there are 2 sides on the coin, heads, and tails.
To find the probability of both these events occurring, multiply both the probabilities together. (5/6) * (1/2) = 5/12.

You now know a lot about all the angles formed from two straight lines that intersect. You know which angles are congruent and which angles are supplementary. Based on this information, you can find the angle measurements of all the angles even when you only know the measurement of one angle. In the figure below, angle 2 measures 145 degrees. What are the measurements of angles 1, 3 and 4? A angle 1 = 35 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees B angle 1 = 30 degrees, angle 3 = 30 degrees, angle 4 = 160 degrees C angle 1 = 35 degrees, angle 3 = 35 degrees, angle 4 = 145 degrees D angle 1 = 135 degrees, angle 3 = 145 degrees, angle 4 = 35 degrees

This is the correct way to set up the equation:
9x + 88 + 6x + 182 = 180
I'm going to move some things around so we can combine like terms. It now reads:
9x + 6x + 88 + 182 = 180
9x + 6x = 15x, so the equation now reads:
15x + 88 + 182 = 180
88 + 182 = 270, so the equation reads:
15x + 270 = 180
Subtract the 270 from both sides. 180 - 270 is -90:
15x = -90
Divide both sides by 15. -90 divided by 15 = -6:
x = -6
Now we can substitute -6 back into the separate equations.
9(-6) + 88 = ?
9 times -6 is -54. -54 + 88 = 34.
6(-6) + 182 = ?
6 times -6 = -36. -36 + 182 = 146
Now we can add 34 and 146 together.
34 + 146 = 180

Answer:
16 inches
Step-by-step explanation:
A cube has 6 sides and to find the surface area you would multiply one side by 6, or add the six sides together. So instead, to find the length of one side, you divide the surface area, 96, by 6 to get 16.
Hope this helps you :)

Step-by-step explanation:
let x be the length of cube=x in
surface area=6 x²
