Answer:

years worked: 14

at least 10 years: 73%

Step-by-step explanation:

The mean is found by adding the years of service and dividing by the number of employees. The total years of service is 417, so the average is ...

average years worked = 417/30 = 13.9 ≈ 14 . . . years

__

The percentage of employees that have worked there at least 10 years is found by counting the number with 10 or more years of service and dividing that count by the total number of employees. The result is then expressed as a percentage.

(10 years or over)/(total number) = 22/30 = 0.73_3 (a repeating decimal) ≈ 73%

_____

Comment on the working

A spreadsheet can be helpful for this. It has a function that can calculate the mean for you. Sorting the years of service into order can make it trivially easy to count the number that are 10 or more, or you can write a function that will do the count for you. (Also, less than 10 means the years are a single digit. There are 8 single-digit numbers in your list.) The hard part is copying 30 numbers without error.

Please solve quickly ​
HACTEHA [7]

Area of a circle = πr^2

Area of a sector with angle x° = (x/360) πr^2

For the smaller sector,

x = 30°

r = 6 in

Required area of sector = (30/360) × π × 6^2 = 9.424 in^2

To the nearest hundreth, Area = 9.42 in^2

How do you solve problem with two variables
nasty-shy [4]

Answer:


In your equations, there is only one variable you're using: y. I do not know what you mean by 2 variables, but probably you copied the wrong equations.  

......Anyways......  

To solve it, you must know that the sum of all 3 angles of a triangle is 180°.  

To set up the equation, add all three angle measures on one side of the equation, and then 180 on the other side. It should be like this:  

(6y+1)+(4y-7)+(9y+3) = 180  

Now that you're done with the set-up, I assume you know what to do next. We can't always do the work for you. ^_~  

> Add up the measures of each angle.  

> Isolate the equation with only variable on one side and only number on the other side.  

> Substitute each variable y for each angle measure and solve it.  

Hope this helps a lot. ^_^
