Answer:
x = 10
x = -1
Step-by-step explanation:
There are 12 months in a year
4.05 inches per month * 12 months per year = 48.6 inches last year
7u^3 - u^2 - 7 + 2u^3 - 4u^2
(7+2)u^3 -(1+4)u^2 - 7
9u^3 - 5u^2 - 7
Answer: 5/36
Step-by-step explanation:
There are 3 ways to do this
Get a 1 and a 5
Get a 2 and a 4
Or get two 3's.
There are two ways to get a 1 and a 5
1 first and 5 second or
5 first and 1 second
The same goes for the 2 and the 4, but NOT for the two 3s.
We have 5 ways to get a sum of 6
What is the probability of one of them happening?
1/6 x 1/6 = 1/36
1/36 chance of one occuring
1/36 x 5 = 5/36 chance of getting a sum of 6 (as there are 5 ways to do so)
