Answer:
A ∩ B = {2, 4}
Step-by-step explanation:
Definition: The intersection A ∩ B of two sets A and B is the set that contains all elements of A that also belong to B.
For example:
If x∈A and x∈B
then;
x∈ A ∩ B
Given the sets:
A = {1, 2, 3, 4, 5} and B = {2, 4}
We have to find A ∩ B.
By definition we have;
A ∩ B = {2, 4}
Therefore, the value of A ∩ B is, {2, 4}
This equals to 10% of the surveyed people which are 50 people
Answer:
8 hours
Step-by-step explanation:
We can use a ratio to solve
12 hours x hours
---------- = ------------
93 dollars 62 dollars
Using cross products
12 * 62 = 93x
Divide each side by 93
12*62/93 = 93x/93
8 = x
8 hours
Answer:
True
Step-by-step explanation:
We have two salaries:
My salary is A
Your salary is B
If I earn 60% more than you
This means that

You must earn 37.5% less than me
The ratio between your salary and mine is:

Your salary is 62.5% of mine. So you earn 100-62.5 = 37.5%. So this is true.
