Step-by-step explanation:
The list shows the number of minutes that eight students spent on math homework last week. 22, 14, 24, 20, 36, 28, 43, 35What is the mean absolute deviation of the numbers
Given:
The data values are:
22, 14, 24, 20, 36, 28, 43, 35
To find:
The mean absolute deviation of the given numbers.
Solution:
We have,
22, 14, 24, 20, 36, 28, 43, 35
The measure of the given numbers is:
[tex]\overline{x}=\dfrac{\sum_{i=1}^{n} x_i}{n}[/tex]
Where, [tex]x_i[/tex] represents the observations and n is the number of observation.
So, the mean value of the given data set is:
[tex]\overline{x}=\dfrac{22+14+24+20+36+28+43+35}{8}[/tex]
[tex]\overline{x}=\dfrac{222}{8}[/tex]
[tex]\overline{x}=27.75[/tex]
The formula for is mean absolute deviation is:
[tex]M.A.D.=\dfrac{1}{n}\sum_{i=1}^{n}|x_i-\overline{x}|[/tex]
The mean absolute deviation of the given numbers is:
[tex]M.A.D.=\dfrac{1}{8}[|22-27.75|+|14-27.75|+|24-27.75|+|20-27.75|+|36-27.75|+|28-27.75|+|43-27.75|+|35-27.75|][/tex]
[tex]M.A.D.=\dfrac{1}{8}[5.75+13.75+3.75+7.75+8.25+0.25+15.25+7.25][/tex]
[tex]M.A.D.=\dfrac{1}{8}[62][/tex]
[tex]M.A.D.=7.75[/tex]
Therefore, the mean absolute deviation of the given numbers is 7.75.

Answer:
angle dgc=90°
angle age=30°
to find=x
angle dgc=angle agb(by vertical opposite angle)
ege is a straight line.
angle age+angle agb+angle bgf=180°[straight line measure 180°]
30°+ 90°+x=180°
120°+x=180°
x=180°-120°
x=60°
In A ABC, mZA= 15° and m2 B = 120°.
Select the triangle that is similar to AABC.
The Triangle MNP in which m∠M = 15 and m∠N = 135 is similar to triangle ABC.
What is the angle sum property?The angle sum property of a triangle states that the sum of the interior angles of a triangle is 180 degrees.
Triangle ABC has the following angle measures:
m∠A = 15° and m∠B = 120°.
We know that the addition of the angles of a triangle makes 180°, therefore:
m∠A + m∠B + m∠C = 180°
Replacing with data and solving for x:
15 + 120 + x = 180
x = 180 - 135
x = 45°
The Triangle MNP in which m∠M = 15 and m∠N = 135 is similar to triangle ABC.

7x-4+8x=6x+8 abcdefghijklmnop
Answer:
x = 4/3
Step-by-step explanation:
7x − 4 + 8x = 6x + 8
Answer:
x=[tex]\frac{4}{3}[/tex]
Step-by-step explanation:
So the equation is 7x-4+8x=6x+8. All we need to do is simplify. On the left side, 7x+8x=15x, so 15x-4=6x+8. Now, we bring the 6x from the right side to the left. When you bring a term from one side to another, you change its sign. As of now, the sign of 6x is positive, so we make it negative and move it to the left side. The new equation is 15x-6x-4=8. Simplifying the left side gives you a new equation of 9x-4=8. Now we move the -4 from the left side to the right side. We change the sign so it becomes 4 and we move it to the right. The equation is now 9x=8+4. 8+4=12, so the final equation is 9x=12. Now we divide by 9 on both sides, giving us the unsimplified answer of x= [tex]\frac{12}{9}[/tex]. We divide the numerator and the denominator by 3 and we get our final answer of x=[tex]\frac{4}{3}[/tex].

Answer and Step-by-step explanation:
The two statements that are true are statement 1 and statement 4:
- The sum of pi and 0 is irrational.
- The product of [tex]\frac{9}{5}[/tex] and [tex]\sqrt{19 }[/tex] is irrational.
Pi is an irrational number, and the square root of 19 is irrational. That's because these numbers can't be put into a simplified fraction to encompass all the digits it contains.
