Respuesta :

Answer:

1)A.{2,3,5,7,11,13}

2) A.{t| t>4}

Step-by-step explanation:

Choose the correct solution in roster form.

1. S is the set of prime numbers that are less than 15

The Definition of a prime number is given as follows:

A prime number can be defined as the number number that can only be divisible of divided by 1 and itself

Hence the list of prime number below 15 is given as:

2, 3, 5, 7, 11 and 13

Hence, option A.{2,3,5,7,11,13} is correct

2. Write the solution to the inequality in set-builder notation.

9t-4>32

Solving for the given inequality

9t > 32 + 4

9t > 36

t >36/9

t > 4

Therefore, the solution to the inequality in set-builder notation is:

Option A.{t| t>4}
