Answer:
1/64
Step-by-step explanation:
We want a second H in the 9th toss. So, we must get only 1 H in the first eight tosses.
So, in the first 8 tosses, we have 1 H and 7 T. Number of ways of getting 1 H and 7 T is 8!/7! = 8
Total possible outcomes = 2^9 = 512
Required probability = 8/512 = 1/64

Answer:
The 80th term is 482
Step-by-step explanation:
8,14,20,26
This is an arithmetic sequence
Find the common difference by taking the second term and subtracting the first term
14-8 = 6
We are adding 6 each time
The formula for an arithmetic sequence is
an =a1+d(n-1) where a1 is the first term, d is the common difference and n is the term we are looking for
a80 = 8+6(80-1)
= 8 + 6*79
= 8+474
= 482
The 80th term is 482
x= 1st integer and then x+1 x+2 and x+3 all add up to 326
x + x+1 + x+2 + x+3 = 326
4x +6 = 326
4x= 320 (divide both sides by 4)
x=80
the Second number is 81
85/100 and in simple terms 17/20
