Answer:
c) 0.0156
Step-by-step explanation:
The general term a[n] of a geometric sequence is given in terms of the first term a[1] and common ratio r as ...
a[n] = a[1]r^(n-1)
The given sequence has an initial term of a[1]=8 and a common ratio of 4/8=1/2. Then the general term is ...
a[n] = 8(1/2)^(n-1)
The 10th term is then ...
a[10] = 8(1/2)^(10-1) = 8(1/2)^9 = 8/512
a[10] = 0.015625 ≈ 0.0156

Ratio of girls to boys is (1/3*X) / (2/3*X).
That is, 1:2
Similarly, ratio of boys to girls is (2/3*X) / (1/3*X).
That is, 2:1
Step-by-step explanation:
- Assume, total Number of students in the class is X. Since, 1/3 part of the class is girls, this makes 2/3 part of the class boys.
- Total number of girls will be equal to 1/3 *X. Total number of boys is equal to 2/3*X.
- So, ratio of girls to boys is (1/3*X) / (2/3*X).
That is, 1:2. Similarly, ratio of boys to girls is (2/3*X) / (1/3*X). That is, 2:1
