Answer:
The last term is 33.
Step-by-step explanation:
Sn = (n/2)(a1 + L) where a1 = first term and L = the last.
So:
-480 = (20/2) ( -81 + L)
-480 = 10( L - 81)
L- 81 = -480 / 10 = -48
L = -48 + 81
L = 33.
Answer:
Step-by-step explanation:
So we start with the given expression:
First, we distribute the negative:
Then, we can combine like terms:
This is our final answer.
Answer:
1/2
Step-by-step explanation:
probability of rolling an odd number is 3/6= 1/2.
probability of rolling a number less than 4 is 3/6= 1/2.
probability of rolling a number that fits both of these is 2/6= 1/3.
