Find the mean absolute deviation (MAD) of the following data set. Round your answer to two decimal places.
3, 10, 6, 9, 7, 4
Answer:The mean absolute deviation (MAD) of the data set=2.17
Step-by-step explanation:
The mean absolute deviation (MAD) is also called the Mean deviation which tells us the variation and average distance of the mean and each data value in a data set.
Given the data set
3, 10, 6, 9, 7, 4
First find the mean
Mean =Sum of data set / Number of data set
=3+10+ 6 +9 + 7+ 4/ 6 =39/6 = 6.5
Next step is to subtract each data set from the mean and ignoring any negative sign accompanied to find the distance from the mean
Value distance from mean
3, 6.5 -3 3.5
10 6.5 -10 3.5
6, 6.5-6 0.5
9, 6.5 -9 2.5
7, 6.5 -7 0.5
4 6.5 -4 2. 5
Last step is to find the mean of the distances which is
Mean Deviation = (3.5+ 3.5+ 0.5+ 2.5+0.5+ 2.5) / 6
=13/6
=2.166666 rounded up to 2.17

The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet. What is the area of the backyard?
Answer:
150 square feet
Step-by-step explanation:
Step 1
Find the Length and Width of the backyard
The length of a rectangular backyard is 5 feet longer than the width of the backyard. The perimeter of the backyard is 50 feet.
Perimeter = 2L + 2W
L = Length, W = Width
L = 5 + W
Hence:
50 = 2(5 + W) + 2W
50 = 10 + 2W + 2W
Collect like terms
50 - 10 = 4W
40 = 4W
W = 40/4
W = 10 feet
We find L
L = 5 + W
L = 5 + 10 feet
L = 15 feet
Step 2
What is the area of the backyard?
Area of a rectangle = Length × Width
Area of the rectangular backyard = 15 feet × 10 feet
= 150 square feet

A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff
Answer:
114%
Step-by-step explanation:
A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff?
Percentage Formula is given as:
New value - Old value/Old value × 100%
New value = 214
Old value = 100
Hence:
Percentage increase = 214 - 100/100 × 100
= 114/100 × 100
= 114 %
Therefore, the percentage increase = 114%

Andrew has 212 coins, all of
which are either quarters or
dimes. The total value of the
coins is $44.90. What is the
value of all of the dimes?
Answer:
158 quarters
54 dimes
Step-by-step explanation:
Let d = no. of dimes
q = no. of quarters
10d = value of all the dimes since each dime is worth 10 cents
and 25q = value of all the quarters since each quarter is worth 25 cents
$44.90 = 4490 cents
10d + 25q = 4490 d + q = 212
- 10d - 10q = -2120
15q = 2370
q = 158 quarters d + 158 = 212
d = 54 dimes

A farmer is creating a budget for planting soybeans and wheat. Planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more than $100,000 planting soybeans and wheat. What is the "multiplier" for soybeans?
Answer:
5 acres < soybeans < 495
2 acres < wheat < 198 acres
Step-by-step explanation:
If farmer plans to plant minimum of soybeans, it should be 5 acres of soybeans costing $1000. The remaining cost of $98,000 will be available for maximum of wheat, i.e., 198 acres of wheat.
Similarly, if we go for minimum possible planting for wheat, it should be 2 acres, and then resulting in 495 acres for soybeans
5 acres < soyabeans < 495
2 acres < wheat < 198 acres
Answer:
The multiplier for soybeans is 200, which is dollars per acre.
Step-by-step explanation:
5 acres ≤ soybeans ≤ 495 acres (constraint)
2 acres ≤ wheat ≤ 198 acres (constraint)
150w + 125s = 100,000
This would represent 150 acres of wheat and 125 acres of soybeans. The acres of wheat would add up to $75,000 because 150 x 500 = 75,000 and the acres of soybeans would add up to $25,000 because 125 x 200 = 25,000. (example of a solution, there are more possible)
A right rectangular prism has a square base and a volume of 225 cubic centimeters. The height, h, of the prism is 9 centimeters. Find the area of the base, B. A. B. C. D.
Answer:
Area of base = 25cm
Step-by-step explanation:
The formula for the volume of a rectangular prism is:
Volume = length × width × height = lwh
for a square base, length = width
∴ volume = l × l × h = l²h
where:
l = length
h = height = 9cm
volume = 225 cm³
∴ 225 = l² × 9
l² = 225 ÷ 9
l² = 25
∴ length = √ 25 = 5cm
Area of base = Length × Length = 5 × 5 = 25cm

Step-by-step explanation:
A scenery is painted on a paper 44cm long and 30cm wide such that there is a margin of 2cm along each of its sides. Find the total area of the margin.
Answer:
280 cm²
Step-by-step explanation:
The computation of the total area of the margin is shown below:
Given that
Length = 44 cm
Breadth = 30 cm
Area of the cardboard = 44 × 30 cm² = 1,320 cm²
Now
Length of the painting eliminating the margin is
= [44 - (2 + 2)] cm
= 40 cm
And,
Breadth of the painting eliminating the margin is
= 30 - (2+ 2)
= 26 cm
Now
Area of the painting eliminating the margin is
= (40 × 26) cm²
= 1,040 cm²
And, finally the total area of the margin is
= (1,320 - 1,040) cm²
= 280 cm²
