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.

The average consumption of milk, m in gallons, per person per year can be approximated by the equation m= -0.13t+8 where t is the number of years after 1997. Predict the consumption of milk in the year 2008. Hint: find the value of t that corresponds to the year 2008.
Answer: 6.57 gallons
Step-by-step explanation:
Given
The average consumption of milk per person per year is
[tex]\Rightarrow m=-0.13t+8[/tex]
In year 2008 i.e. t=2008-1997=11 years
Put the value in the equation
[tex]\Rightarrow m=-0.13\times 11+8\\\\\Rightarrow m=-1.43+8=6.57\ \text{Gallons}[/tex]
So, it is 6.57 gallons in year 2008

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°

A lake near The Arctic Circle is covered by a thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing it’s thickness to decrease at a rate of 0.2m per week. After 7 weeks, the sheet is only 2.4m thick.
Let y represent the ice sheets thickness (in meters) after x weeks.
Complete the equation for the relationship between the thickness a number of weeks.

if you walk 2 1/4 miles in 3/4 miles, how far can you walk in 2 1/2
2 1/2 = 5/2
1 3/4 = 7/4
(5/2)/1 = x/(7/4) set up a proportion: 5/2 miles in 1 hour = x miles in 7/4 hours
x = (5/2)*(7/4)
x= 35/8
5/6 x 1/3 - 1-9

2. Find the slope, or rate of change, represented in the table below. -1 x 0 1 2 3 Y-8 3 14 25 36
Answer:
11
Step-by-step explanation:
Given the data:
X: - 1 _ 0 _ 1 _ 2 _ 3
Y: -8 _ 3 _ 14 _ 25 _36
Slope = Rise / Run
Rise = y2 - y1 = 36 - (-8) = 36 + 8 = 44
Run = x2 - x1 = 3 - (-1) = 3 + 1 = 4
Slope = 44 / 4
Slope = 11
Rate of changeb/ slope = 11
