How many subsets can be made from a set of six elements, including the null set and the set itself?

84

Each element is either included or not in a subset.

Hope this helps you out!

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.

step-by-step explanation:

it is contrapositive
