Round 2,042,822 to the nearest 1,000

andre [41]

To round a number to the nearest thousands, we will check the number is the hundreds position:
if the number in the hundreds position is smaller than 5, then we will convert all numbers after the thousands position to zeroes
if the number in the thousands position is equal to or greater than 5, we will add one to the thousands and convert all digits after it to zeroes.

The number we have is 2,042,822
Applying the above concept we will find that:
the number in the hundreds position is 8 which is greater than 5
Therefore:
2,042,822 to the nearest thousands is 2,043,000

A company decides to investigate the amount of sick leave taken by its employees. A sample of seven employees yields the followi

Svet_ta [14]

Using statistical concepts, we have that:

a. The range is 6 days, and the interpretation is: B. The number of days separating the fewest and most sick days taken is equal to the range.

b. The standard deviation is of 2.2, which means that the average spread about the mean is of 2.2 units.

<h3>Range and standard deviation:</h3>

The range of a data-set is given by the difference between the highest value and the lowest value in the data-set.

The standard deviation of a data-set is given by the square root of the sum of the difference squared of each observation and the mean, divided by the number of observations.

Item a:

The lowest value is of 0.

The highest value is of 6.

Hence:

The range is 6 days, and the interpretation is: B. The number of days separating the fewest and most sick days taken is equal to the range.

Item b:

The mean is:

$M = \frac{0 + 1 + 4 + 0 + 0 + 6 + 3}{7} = 2$

Hence, the standard deviation is:

$S = \sqrt{\frac{(0-2)^2+(1-2)^2+(4-2)^2+(0-2)^2+(0-2)^2+(6-2)^2+(3-2)^2}{7}} = 2.2$

The standard deviation is of 2.2, which means that the average spread about the mean is of 2.2 units.

Solve the system of equations system

Korolek [52]

Answer:

(3, 3 )

Step-by-step explanation:

Given the 2 equations

3x - y = 6 → (1)

6x + y = 21 → (2)

Adding the 2 equations term by term will eliminate y, that is

(6x + 3x) + (y - y) = (21 + 6), that is

9x = 27 (divide both sides by 9 )

x = 3

Substitute x = 3 into either (1) or (2) and solve for y

Using (2), then

(6 × 3) + y = 21

18 + y = 21 ( subtract 18 from both sides )

y = 3

Solution is (3, 3 )
