What is the MAD of these numbers 1,1,4,5,5,5,6,7,7,10,10?
Please give an explanation
Answer:
2.2314
Step-by-step explanation:
To find the mean absolute deviation of the data, start by finding the mean of the data set.
1+1+4+5+5+5+6+7+7+10+10= 61
61÷11= 5.5-2.5= 2.2
Example:
Find the MAD of 2,4,6,8
Step 1 :
Find the mean of the data :
(2+4+6+8) / 4 = 20/4 = 5
Step 2 :
Find the distance between each data and mean.
Distance between 2 and 5 is 3
Distance between 4 and 5 is 1
Distance between 6 and 5 is 1
Distance between 8 and 5 is 3
Step 3 :
Add all the distances :
3+1+1+3 = 8
Step 4 :
Divide it by the number of data :
8 / 4 = 2

Find the area of equilateral triangle with side a. Please answer with completely simplified exact values. Answer: A = sq. Units
Solution :
It is given that the length of a side of a triangle is given by 'a'.
It is an equilateral triangle.
So the three sides will be of equal length and is a, a, a units.
Now the semi perimeter of the equilateral triangle is given by :
[tex]$S=\frac{a+a+a}{2}$[/tex]
[tex]$=\frac{3}{2}a$[/tex]
Therefore, using the Heron's formula, we can find the area of the equilateral triangle.
Area of the equilateral triangle is given by :
[tex]$A =\sqrt{S(S-a)(S-a)(S-a)}$[/tex]
[tex]$A =\sqrt{\frac{3a}{2}\left(\frac{3a}{2}-a\right)\left(\frac{3a}{2}-a\right)\left(\frac{3a}{2}-a\right)}$[/tex]
[tex]$A=\frac{\sqrt3}{4}a^2$[/tex] square units.

Write the point-slope form of the equation of the line that passes through the points (-8, 2) and (1, -4). Include your work in your final answer. Type your answer in the box provided to submit your solution.
Answer:
[tex]\displaystyle (y - 2) = -\frac{2}{3}\, (x + 8)[/tex].
Step-by-step explanation:
Given two points [tex](x_0,\, y_0)[/tex] and [tex](x_1,\, y_1)[/tex] on a line in [tex]\mathsf{2D}[/tex], the slope of that line would be:
[tex]\begin{aligned} m &= \frac{y_1 - y_0}{x_1 - x_0} \\ &= \frac{-4 - 2}{1 - (-8)} = -\frac{2}{3}\end{aligned}[/tex].
For a line with slope [tex]m[/tex] and a point [tex](x_0,\, y_0)[/tex], the point-slope equation of that line would be:
[tex]y - y_0 = m \, (x - x_0)[/tex].
It was already found that for this line, slope [tex]\displaystyle m = -\frac{2}{3}[/tex]. Take [tex](x_0,\, y_0) = (-8,\, 2)[/tex]. That is: [tex]x_0 = -8[/tex] and [tex]y_0 = 2[/tex]. Find the equation of this line in point-slope form:
[tex]\displaystyle (y - \underbrace{2}_{y_0}) = \underbrace{\left(-\frac{2}{3}\right)}_{m}\, (x - \underbrace{(-8)}_{x_0})[/tex].
Equivalently:
[tex]\displaystyle (y - 2) = -\frac{2}{3}\, (x + 8)[/tex].

If a⁵ = 3⁵, simplify (2a)⁷ ?
3⁷3⁸6⁶6⁷Answer :D option 6⁷ is the right answer.Explanation :Given :a⁵ = 3⁵To Find :(2a)⁷Solution :As, we have a⁵ = 3⁵
We know that if powers are equal then the base are also equal. In a⁵ = 3⁵, powers are equal on both sides so base will also be equal.
∴ a = 3
Now, we have to find (2a)⁷, so by substituting a = 3, we have :
⟹ (2a)⁷ = (2 × 3)⁷
⟹ (2a)⁷ = (6)⁷
⟹ (2a)⁷ = 6⁷
Therefore, correct answer is 6⁷.
Hence, correct option is D.

The difference of two numbers is 4. Their sum is 32. What are the numbers?
• x + y = 4
• x - y = 4
• x + y = 32
• x - y = 32
Answer:
x-y=4
and
x+y=32 is your equation
difference of two number =x-y is equal to 4
sum of two number=x+y is equal to 32
x-y=4.......(1)
x+y=32.......(2)
adding equation 1 and 2
x-y +x+y=4+32

John is planning on building a shelf in the shape of a right triangle. He wants the shelf to be 99 inches at its widest and 4040 inches long. He believes the diagonal will be 41 inches. Is he accurate?
Given:
Shape of the shelf is a right triangle.
Width of the shelf = 9 inches
Length of the shelf = 40 inches
He believes the diagonal will be 41 inches.
To find:
Whether he is accurate or not.
Solution:
According to the Pythagoras theorem,
[tex]Hypotenuse^2=Perpendicular^2+Base^2[/tex]
Using Pythagoras theorem, find the length of the diagonal.
[tex]Diagonal^2=Width^2+length^2[/tex]
[tex]Diagonal^2=(9)^2+(40)^2[/tex]
[tex]Diagonal^2=81+1600[/tex]
[tex]Diagonal^2=1681[/tex]
Taking square root on both sides.
[tex]Diagonal=\pm \sqrt{1681}[/tex]
But side cannot be negative.
[tex]Diagonal=41[/tex]
Therefore, the length of the diagonal is 41 inches. So, John is accurate.

Calculate the equation of the line through the points (-1, 1), (4.0), and (24,-4).
A y = 5x + 6
B y= 1/5x + 4/5
C y= -5x + 4
D y= -1/5x +4/5
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 1) and (x₂, y₂ ) = (24, - 4) ← 2 points on the line
m = [tex]\frac{-4-1}{24+1}[/tex] = [tex]\frac{-5}{25}[/tex] = - [tex]\frac{1}{5}[/tex] , then
y = - [tex]\frac{1}{5}[/tex] x + c ← is the partial equation
To find c substitute any of the 3 points into the partial equation
Using (4, 0 ) , then
0 = - [tex]\frac{4}{5}[/tex] + c ⇒ c = 0 + [tex]\frac{4}{5}[/tex] = [tex]\frac{4}{5}[/tex]
y = - [tex]\frac{1}{5}[/tex] x + [tex]\frac{4}{5}[/tex] → D
