30% of a number is 45 what is the number ?

adell [148]

Hey there! I'm happy to help!

When talking about percents, the word "is" usually means equals. Let's use this to solve an equation! We will call our number n. Note that 30% is equal to 0.3 in decimal form because 0.3 is 30% of one! :D

0.3n=45

To solve, we need to isolate the n. To do this, we divide both sides by 0.3 because this cancels out the 0.3 that is being multiplied by n and it shows us what n will then equal.

0.3n÷0.3=45÷0.3

n=150

Therefore, 30% of 150 is 45. Try multiplying 0.3 by 150 and you will get 45!

Have a wonderful day! :D

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 <u>between the highest value and the lowest value in the data-set</u>.

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

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.
