Answer:
-2/3
Step-by-step explanation:
Okay, this is a fairly simple question.
First, you want to pick two pairs of coordinates (X,Y).
In this case, I chose (-3, 5) and (3, 1)
Now, you want to use the formula to find slope : y2-y1/x2-x1
1-5/3-(-3)
-4 divided by 6
=-2/3
The odds of getting a red first is 5/12. the odds of getting a green second is 7/11. the probability of both is then 5/12 * 7/11, or 35/132
Average weight is when you add up all the weight and divide by the number of objects
if you count the number of x's you will see that you have 10 sandwiches
now add up all the weight
1/8 +1/8+ 1/4+1/4+1/4+1/4+ 3/8+ ....
once you have total weight, divide that number by 10
