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}.

the question is 7a + 10 = 2a
Answer:
a = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 - 10 = 2a - 10
Simplify:
7a = 2a - 10
Subtract 2a from both sides:
7a - 2a = 2a - 10 - 2a
Simplify:
5a = -10
Divide both sides by 5 and simplify:
a = -2
Answer:
A = -2
Step-by-step explanation:
Subtract 10 from both sides:
7a + 10 = 2a -10
Simplify the expression, 7a = 2a - 10
Subtract 2a from both sides next
7a - 2a = 2a - 10 - 2a
Subtract 7a - 2a
5a = -10
5a / 5 = -10/5
a = -2

Supply and demand coordinate to determine prices by working together.
What is supply and demand?Supply and demand work hand in hand when determining prices of goods and service in the market.
According to the law of demand the higher the price of goods in the market the lower the demand for those goods while the law of supply states that the higher the price the higher the supply.
In the market the supply and demand plays an important roles as it enables consumer to determine the actual prices and quantity of goods in the market.

Simplify Using Distributive Property
-6(2a + 8)
Answer:
-12a - 48
Step-by-step explanation:
you do -6 times 2a which is -12a then you do -6 times 8 which gives you -48 so you put -12a - 48
since the 48 is a negative we would just put a minus sign instead a plus. If it was a positive 48 we would put a plus sign buts its not so we put a negative.
[tex]\huge\boxed{\mathcal{HELLO!}}[/tex]
The distributive property states that
a(b+c)=ab+ac (we multiply a by everything inside the parentheses)

Ainsley walks 3/5 mile in 1/3 of a day. Sarah walks 5/8 mile in 2/6 of a day. Who walked farther, Ainsley or Sarah? Find the unit rate for each girl and then tell who you think walked farther with the correct unit rate given below. *
[tex]Ainsley \: walked \: in \: \frac{1}{3} \: \: of \: a \: day \ \: = \frac{3}{5} mile[/tex]
[tex] = \frac{1}{3} \times 24 = \frac{3}{5} [/tex]
[tex]8 \: hours = \frac{3}{5} \: miles[/tex]
[tex]Sarah \: walked \: in \: \frac{2}{6} of \: a \: day \: = \frac{5}{8} miles[/tex]
[tex] \frac{2}{6} \times 24 = \frac{5}{8} [/tex]
[tex]8 \: hours \: = \frac{5}{8} \: miles[/tex]
Let us see who walked more :
[tex]Ainsley \: walked \: = \frac{3 \times 8}{40} [/tex]
[tex] = \frac{24}{40} \: miles[/tex]
[tex]Sarah \: walked \: = \frac{5 \times 5}{40} [/tex]
[tex] = \frac{25}{40} \: miles[/tex]
[tex] \frac{24}{40} < \frac{25}{40} [/tex]
Sarah walked farther than Ainsley .
[tex] \frac{25}{40} - \frac{24}{40} = \frac{1}{40} \: miles[/tex]
∴ Sarah walked farther than Ainsley by 1/40 miles .
