Which set of population data is the least dispersed from its mean?
O 2, 3, 2,9
O 4, 0, 4,0
O 6, 2, 2, 2
O 9, 3, 5,3
Answers
Answer: (C)
6,2,2,2
Step-by-step explanation:
A mean is an arithmetic average of a set of observations. The set of population data that is the least dispersed from its mean is {6, 2, 2, 2}.
What is Mean?
A mean is an arithmetic average of a set of observations. it is given by the formula,
[tex]\rm Mean=\dfrac{\text{Sum of all obervation}}{\text{Number of observation}}[/tex]
To solve the problem we will find the mean of each population set and then add the difference between the mean and each data point.
A.)
[tex]Mean = \dfrac{2+3+2+9}{4} = \dfrac{16}{4} =4[/tex]
Dispersion of each point from the mean,
[tex]\rm |Mean - data\ point|\\|4-2|=2\\|4-3|=1\\|4-2|=2\\|4-9|=5[/tex]
Thus, the dispersion of the population from the means is 10 (2+1+2+5).
B.)
[tex]Mean = \dfrac{4+0+4+0}{4} = \dfrac{8}{4} =2[/tex]
Dispersion of each point from the mean,
[tex]\rm |Mean - data\ point|\\|2-4|=2\\|2-0|=2\\|2-4|=2\\|2-0|=2[/tex]
Thus, the dispersion of the population from the means is 8 (2+2+2+2).
C.)
[tex]Mean = \dfrac{6+2+2+2}{4} = \dfrac{12}{4} =3[/tex]
Dispersion of each point from the mean,
[tex]\rm |Mean - data\ point|\\|3-6|=3\\|3-2|=1\\|3-2|=1\\|3-2|=1[/tex]
Thus, the dispersion of the population from the means is 6 (3+1+1+1).
D.)
[tex]Mean = \dfrac{9+3+5+3}{4} = \dfrac{20}{4} =5[/tex]
Dispersion of each point from the mean,
[tex]\rm |Mean - data\ point|\\|5-9|=4\\|5-3|=2\\|5-5|=0\\|5-3|=2[/tex]
Thus, the dispersion of the population from the means is 8 (4+2+0+2).
Hence, the set of population data that is the least dispersed from its mean is {6, 2, 2, 2}.

Suppose that a family wants to increase the size of the garden which is currently 16 feet long and 8 feet wide without changing the basic shape of the garden. That is, the family wants to ensure that the length of the garden remains twice the width (see figure).
1. Write an equation for the area of the new garden.
2. Write an equation that calculates how much more area the new garden will have as compared to the current garden. Simplify the equation into a quadratic equation in standard form.
3. Using the equation from Exercise 2, determine what effect increasing the width of the garden by two feet will have on the length of the garden and the total area of the garden.
4. Using the equation from Exercise 2 and factoring, determine how much the width of the garden will need to be increased in order for the garden area to be 160 square feet larger than its original area.
5. Using the equation from Exercise 2 and factoring, determine how much the width of the garden will need to be increased in order for the garden area to be four times its original area.
Answers
Answer:
See below
Step-by-step explanation:
Sides of the garden
16 feet and 8 feetNew dimensions of the garden
16 + 2x and 8 + x1. The area of the new garden
(16 + 2x)(8 + x) = 2x^2 + 32x + 1282. The difference in area
2x^2 + 32x + 128 - 16*8 = 2x^2 + 32x3. x= 2 effect on the area
2*2^2 + 32*2 = 8 + 64 =72 ft²4. Area difference = 160
2x^2 + 32x = 160x^2 + 16x - 80 = 0Solving we get positive root of 4 ft5. Area difference = 4 times
2x^2 + 32x = 128*32x^2 + 32x - 384 = 0x^2 + 16x - 192= 0Solving we get positive root of 8 ftI need help please, can you help me?

Kareem earns y dollars per month at his accounting job. Express his annual salary using
the K abbreviation found in classified ads.
Answers
Answer:
0.012yK
Step-by-step explanation:
[tex]\frac{y*12}{1000} K[/tex] > K=1,000
12 divided by 1000 is 0.012.
The required annual salary for Kareem is 0.012yK.
Given that,
Kareem earns y dollar per month at his accounting job. Express his annual salary using the K abbreviation found in classified ads is to be determined.
The process in mathematics to operate and interpret the function or expression to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
$1 K = $1000 (for a year)
Since salary for a month is y
Salary for a year = 12 * y
Transforming it into K abbreviation
Multiplied and divide by 1000 on the right side
Annual salary = 12 y 1000 /1000
= 12/1000 * y K
= 0.012yK
Thus, the required annual salary for Kareem is 0.012yK.
