Answer: -418, 728, 446, -429, 1159, -696

Step-by-step explanation:

1. $n = -199 - 219 = \boxed{-418}$ .

2. $m = 438 - (-290) = 438 + 290 = \boxed{728}$ .

3. $128 - (-318) = 128 + 318 = \boxed{446}$ .

4. The sum of 429 and 429 is $429+429 = 858$ . We need to subtract this from 429, so $429 - 858 = \boxed{-429}$ .

5. The sum of 510 and 319 is $510+319 = 829$ . Subtracting -330, we get $829 - (-330) = 829 + 330 = \boxed{1159}$ .

6. Call the unknown number " $\star$ ". Then $\star + 298 = -398$ , so $\star = -398 - 298 = \boxed{-696}$ . (Think about it.)

If Benito is selecting samples of five values from the table, which row will result in the greatest mean? Population Data Row 1

Vilka [71]

Answer:

4th row will result in the greatest mean.

Step-by-step explanation:

We are asked to find the row with greatest mean from our given rows.

We will use formula $\bar{x}=\frac{\Sigma x}{n}$ , where,

$\bar{x}=\text{Mean}$ ,

$\Sigma x=\text{Sum of all data values}$ ,

$n=\text{Number of data points in sample}$

Let us find mean of each row using above formula.

$\text{Mean of row 1}=\frac{4+2+2+3+3}{5}$

$\text{Mean of row 1}=\frac{14}{5}$

$\text{Mean of row 1}=2.8$

Therefore, mean of 1st row is 2.8.

$\text{Mean of row 2}=\frac{3+3+4+3+2}{5}$

$\text{Mean of row 2}=\frac{15}{5}$

$\text{Mean of row 2}=3$

Therefore, mean of 2nd row is 3.

$\text{Mean of row 3}=\frac{2+4+3+4+3}{5}$

$\text{Mean of row 3}=\frac{16}{5}$

$\text{Mean of row 3}=3.2$

Therefore, mean of 3rd row is 3.2.

$\text{Mean of row 4}=\frac{3+4+4+7+3}{5}$

$\text{Mean of row 4}=\frac{21}{5}$

$\text{Mean of row 4}=4.2$

Therefore, mean of 4th row is 4.2.

Since 4th row has the highest mean, therefore, 4th row will result in the greatest mean.
