Let n be a randomly selected integer from 1 to 20. find the indicated probability.
n is prime given that it has two digits, what is n?

There us 11 two digit numbers between 1 and 20.
4 of them are prime: 11, 13, 17 and 19

so probability is 4/11

Hiya!

Let's assume that you have the unlimited texting plan, which is $30. You also have 500 minutes which is $20. Your total is $50 for one month.

We can assign variables to represent this in our equation. 'u' can be for unlimited texting, 'm' can be minutes, 'a' can be additional minutes, and 'o' can represent one month.

If you plug all of this into an equation, it'll look something like this:

50o=30u+(20m+.45a)

Hopefully this checks out :p Check with your math teacher to make sure this is right.
