Convert to a mixed number:
13/3
Divide 13 by 3:
3 | 1 | 3
3 goes into 13 at most 4 times:
| | 4
3 | 1 | 3
- | 1 | 2
| | 1
Read off the results. The quotient is the number at the top and the remainder is the number at the bottom:
| | 4 | (quotient)
3 | 1 | 3 |
- | 1 | 2 |
| | 1 | (remainder)
The quotient of 13/3 is 4 with remainder 1, so:
Answer: 4 1/3
Answer:
Sₙ = √5/2 n (n + 1)
Step-by-step explanation:
<u>Given AP:</u>
<u>Rewriting as:</u>
- √5,√4*5,√9*5,√16*5,...
- √5, 2√5, 3√5, 4√5,..., n√5
<u>Common difference:</u>
<u>Sum of n terms:</u>
- Sₙ = 1/2n (a₁ + aₙ) =
- 1/2n (√5 + √5 + (n-1)√5) =
- 1/2n (n + 1)√5=
- √5/2 n (n + 1)
Sₙ = √5/2 n (n + 1)

Answer:
1/2
Step-by-step explanation:
The coin is balanced, so if we call p the probability of heads, then p must be equal to 1-p, the probability of tails. Since p = 1-p, then 2p = 1, therefore p = 1/2. As a consecuence, there is a probability of 1/2 that the number of heads obtained is 1, and a probability of 1/2 that the number of heads obtained is 0.
I hope this works for you!
