An office has 80 employees, and 24 of the employees are managers. What percentage of the employees are managers?

andreyandreev [35.5K]

Solution:

30% of the employees are managers.

Explanation:

We have been given that there are 80 employees, and 24 of the employees are managers.

We have to find the percentage of the employees that are managers.

We can find this percentage with the below formula

$\% = \frac{\text{Number of managers}}{\text{Total number of employee}}\times 100$

On substituting the known values, we get

$\%=\frac{24}{80}\times 100\\\%=\frac{3}{10}\times 100\\\%=3\times 10\\\%=30\%$

Therefore, 30% of the employees are managers.

Combine any like terms in the expression. If there are no like terms, rewrite the expression.

stich3 [128]

Answer:

40w^3

Step-by-step explanation:

I'm assuming you meant w^3 (w to the third power). In that case, you would just add 34 + 13 + 11 - 18 because they are all like terms (coefficients of w^3).

Please HELP ASAP!!! The dot plot show the number of hours teenagers spent on two different websites last week. Which statement i

Delvig [45]

Answer:

(F.) the mode of the data for website K is greater than the mode of the data from website L

Step-by-step explanation:

Mode simply means the parameter that occurs the most.

In website K, the one that occurs the most is 8 hours while in website L, the one that occurs the most is 2 hours.

This means that mode of website K is greater than that of website L.

Thus,statement F is correct

Range is the difference between the highest value and the lowest value..

For website K, Range = 14 - 1 = 13

For website L, Range = 13 - 1 = 12

Thus,range of both websites are not the same and as such statement G is wrong.

For a symmetrical distribution, the left and right hand sides of the centre value line of the distribution have to mirror each other.

In this case neither website K nor L have that. Thus, statement H is not correct.

Skewed to the left means that more o

dot points are found to the left of the graph.

For website L, more dot points are located to the left while for website K, it's not the case. Thus, statement J is not correct
