(1) answer for this question is 6/51 to 1
(2)the answer for this question is (d)58.50
Step-by-step explanation:
Initially, there's only 1 letter.
Tania sends the letter to 4 friends.
Each friend sends a letter to 4 more friends (4 × 4 = 16).
Each of those friends sends to 4 more friends (16 × 4 = 64).
The pattern is 1, 4, 16, 64, etc.
This is a geometric sequence. The first term is 1 and each term is 4 times the previous term.
a₁ = 1
aₙ = 4 aₙ₋₁
The explicit formula is:
aₙ = 1 (4)ⁿ⁻¹
Answer:

Step-by-step explanation:
The total length of this line is 15 units. FG is 6 units long.
This means that the probability of p being on FG would be
which can be simplified to 
Answer:
The slope is 5/7 and it rises
Step-by-step explanation:
(-4,1) and (3,6)
6 - 1 / 3 - (-4)
5 / 3+4
= 5 / 7
and it rises since the answer is positive
