How to find each one: So first, if you have a fraction, (you probably want to simplify the ones you've put in by dividing both sides by the same number, for example, 45/100, both sides by 5, 9/20)
So if you have a fraction:
You can find the ratio by just putting the numerator on the left, n:, and the denominator on the right. n:d
For example, with 5/9, 5:9.
For decimal, you can just divide. For example, 4/5, 0.8.
Percent, just change the decimal to have a hundredths place, with 0.8, 0.80, and then just take those two digits, or 80%.
So basically, for ratio, you can do it if you have the fraction.
For the column fraction, if you know basic fractions, you can also convert from those, and also from the ratios.
For decimal, if you know percent or fraction, you should be able to find it.
Percent, fraction or decimal should work.
I'll do a row to explain, it's kind of confusing, sorry:
So if you have 9:20, you can convert that to the fraction, 9/20.
Then you can find the decimal, 9/20 = 0.45
Percent would therefore be 45%.
Hope this helped :)
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.
-11 ,-3, -6, 0, 7, 9 I hope im right
Answer:
y-intercept (0,11/5)
x-intercept (11/2,0)
Step-by-step explanation:
The y-intercept is obtained when the x-coordinate equals 0 (x=0)
so the y-intercept is (0,11/5)
The x-intercept is obtained when the y-coordinate equals 0 (y=0)
In this case
0 = -(2/5)x+11/5---->(2/5)x = 11/5 ----> x=(5*11)/(5*2) = 11/2
So the x-intercept is (11/2,0)
It is a scalene triangle as all the sides are unequal in length.
