Set h is defined as h={x|x is prime}. which of the following is a subset of h? a.{2,13,23} b.{x|x is an integer} c.{x|x is odd} d.{1,2,3,4}

a.{2,13,23}

Step-by-step explanation:

set h is defined as h={x|x is prime}

Some prime numbers are

2, 3, 5, 7, 11, 13, 17, 19, 23 ,29,31 and so on

a.{2,13,23} : 2, 13 and 23 are the prime numbers so they are the subset of h

b.{x|x is an integer} : all the integers are not prime numbers so it is not a subset of h

c.{x|x is odd}: all the odd numbers are not prime numbers so it is not a subset of h

d.{1,2,3,4}: 4 is not a prime number so it is not a subset of h

where is the option given

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
