And third division. Shad (b) Among 500 examinees, the ratio of students passed in first and 2nd division is 1:3. If 60 were passed in third division and 40 were failed, find the ratio of the students passed in first, second and third division please help me

Total Number of student = 132 The ratio of the pass : fail = 9 : 2 Number of student pass =  

911×132=108911×132=108

Number of student fail =  

211×132=24211×132=24

Now 4 student more passed.

∴ Number of student pass = 108 + 4 = 112 and,

Number of student fail = 24 - 4 = 20

New ratio of pass : fail = 112 : 20 = 28 : 5

Step-by-step explanation:

omg you don't no answer of that question manner less

Hello there! :D

Well, it is a general rule of thumb that growth is indicated by positive numbers, and decay is indicated by negative numbers. I would show decay in this exponential equation by making the percentage inside the parenthesis negative. It would look like this: y=4800(-1.239)

Obviously, this equation does not have a negative integer so we know it must constitue growth!

I hope this helped you and that you have a wonderful day,
