A. 4
If it's an absolute value question then the absolute value of 12-8 is four
Using the given assumption, there are 3.
The sample space for rolling two dice and finding the sum is:
2 3 4 5 6 7
3 4 5 6 7 8
4 5 6 7 8 9
5 6 7 8 9 10
6 7 8 9 10 11
7 8 9 10 11 12
From the sample space alone, there are 5. However, since a 3 and a 5 is the same as a 5 and a 3, this means that 2, 6 is the same as 6, 2 as well; this takes 2 off of the 5, leaving us 3.
$50 per day x 6 days = 300
20% = 0.2, times t = 0.2t
The equation would be: f(t) = 300 + 0.2t
