Answer 1

Answer: (C)

6,2,2,2

Step-by-step explanation:

Answer 2

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}.

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. *

Answers

[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 .

Answers

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.

the question is 7a + 10 = 2a

Answers

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

HELPPPPPText (for the second one)The captains needed to keep the slaves in acceptable physical condition if they were to be sold at high prices, so each morning after breakfast the slaves were danced on deck, in order to give them exercise. Still shackled together, the men were forced to jump up and down until often the flesh of their ankles was raw and bleeding from the iron chains from which bound them together. The women and children, who were free of such bonds were better able to dance to the rhythm that was pounded out on an African drum or iron kettle, sometimes with the accompaniment of a fiddle or African banjo played by a crew member. The slaves, otherwise kept miserable in the tween decks, enjoyed this dancing, as it was their only form of physical recreation during the entire day. Each day at sunset the slaves would be placed back below deck to rest in the misery and filth that was the tween decks. QUESTION:2. What does this text reveal about the first Africans to be brought to North America?Text (for the third question)During the morning exercises members of the crew roved about the deck carrying whips and would beat those slaves who refused to dance. Although most whips were made only of simple rope, the wicked cat-o-nine-tails was used aboard many slavers.

The tween decks were often full not only with slaves, both living and dead, but also with blood, vomit, urine, and human waste. Also during periods of inclement weather the slaves were not fed as usual. They were often forced to scrounge for small crumbs and pieces of spoiled food and drink from stagnant puddles of extremely pure water.QUESTION:5. What does this text reveal about the first Africans to be brought to North America?TEXT (for the sixth question)During the periods of good weather, the slaves would be brought up on deck in the morning. At this time the men would be shackled together with iron chains, while the women and children would be allowed to roam about on deck. At about nine o clock in the morning they were given their first meal of the day. Interestingly, slaves from different sections along the West African coast would often be fed different meals. Those from the Northern part of the Guinea coast would be fed boiled rice, millet, or cornmeal. Slaves from the Bight of Biafra had stewed yams, and those from still farther south in the Congo River region would be fed starchy manioc, cassava flour, or banana-like fruits. Sometimes a few lumps of raw meat would be thrown in with their food to keep them healthy. It was also at this time in the morning that the slaves were given their daily ration of a half-pint of water in a small pan, called a pannikin.In the late afternoon came the slaves second and only other meal of the day. Sometimes it was the same as their first, but most captains were not that humane. The afternoon meal usually consisted of horse beans, very large beans which are used to feed horses.
