Step-by-step explanation:
You can isolate r to one side of the equation by dividing by adding three, dividing by s, multiplying by a and you get:
r=a(3+k)/s
In order to estimate the mean, you need to choose a value to represent the number in each category of accidents. It is often convenient to use the middle value of the range.
.. (4*6 +10*10 +15*6 +20*9)/(6 +10 +6 +9) = 394/31 ≈ 12.7
You see what the average is in each class. (Divid students and classes) and add them together and divid by four. You should get 18 if you round to the whole number.
20/10 as a mixed number:
20 ÷ 10 = 2.
10 goes into 20 two times. So 20/10 as a mixed number is a whole number: 2.
20/10 = 2
