E ∩ F = {}

Step-by-step explanation:

Intersection is an operation performed on sets. In intersection, the common elements of the sets involved are written,

Given

E = {1, 2, 3}

F = {101, 102, 103, 104}

We have to find the intersection of both sets as indicated

So,

E ∩F = {1, 2, 3} ∩ {101, 102, 103, 104}

E ∩ F = {}

As there are no common elements in both sets the intersection will be an empty set

Vinil7 [7]

Answer:

a) $12x = 15000$

b) $x = 1250$

Step-by-step explanation:

Given: A thrill ride at an amusement park holds a maximum of 12 people per ride.

To find :

a. An inequality that you can use to find the least number of rides needed for 15,000 people.

b. Then find the least number of rides needed for 15,000 people.

Solution :

Let x represent the number of rides.

a) A ride holds maximum of 12 people = 12x

To find an inequality of the least number of rides needed for 15,000 people.

The equation is $12x = 15000$

b) Find the least number of rides needed for 15,000 people.

Solve the equation,

$12x = 15000$

$x = \frac{15000}{12}$

$x = 1250$

Answer is x=1250
