lara31 [8.8K]

Answer:

900

Step-by-step explanation:

Margin of error = critical value × standard error

The margin of error is given to be 0.05.

At 99.5% confidence, the critical value is z = 3.

The standard error for a proportion is √(pq/n).  Since p is not given, we will assume p = 0.5.

0.05 = 3 √(0.5 × 0.5 / n)

n = 900

A sequence can be generated by using an=3a(n−1),where a1 =5 and n is a whole number greater than 1. What are the first four term
umka2103 [35]

Answer:

5, 15, 45 and 135

Step-by-step explanation:

Given the recursive function;

an = 3a(n-1)

If a1 = 5

a2 = 3a1

a2 = 3(5)

a2 = 15

For a3;

a3 = 3a2

a3 = 3(15)

a3 = 45

For a4;

a4 = 3a3

a4 = 3(45)

a4 = 135

Hence the first four terms are 5, 15, 45 and 135
