Answer is in the sheet, hope this helps!
Here is how you would set it up...
You would to 12/100 = x/2 and cross multiply and solve by division. I believe. I'm almost positive that's how you do it. If that don't work out, comment and I'll respond.
Answer:
3.80
Step-by-step explanation:
The slope is 3.5, also known as 3 1/2.
A factor of 30 is chosen at random. What is the probability, as a decimal, that it is a 2-digit number?
The positive whole-number factors of 30 are:
1, 2, 3, 5, 6, 10, 15 and 30.
So, there are 8 of them. Of these, 3 have two digits. Writing each factor on a slip of paper, then putting the slips into a hat, and finally choosing one without looking, get that
P(factor of 30 chosen is a 2-digit number) = number of two-digit factors ÷ number of factors
=38=3×.125=.375
