Answer:
37/40
Step-by-step explanation:
There are 3 numbers between 1 and 40 that are a multiple of 13: 13,26,39.
So, your probability should be 40-3/40, = 37/40.
D as you can see on the number line d is 1/3 of the way to -2
Step-by-step explanation:
a < (a + b)/2 < b
Solve the first inequality.
a < (a + b)/2
2a < a + b
a < b
Solve the second inequality.
(a + b)/2 < b
a + b < 2b
a < b
Both inequalities are true. Therefore, a < (a + b)/2 < b.
