Answer:
{∅, {a}, {b}, {a,b}}
Step-by-step explanation:
The value of power of a set is generalized by using the formula,
Power of a set (P) = 2^n where n is the number of element in the set.
Given two distinct elements a and b say;
A = {a,b}
n(A) = 2 i.e the number of elements in the set is 2. Therefore the power of the set will be 2^n which gives 2^2 = 4.
P(A) = 4 means there are 4 subsets of the given set. Subsets are sets of elements that can be found in the set. The subsets of element A will be;
{∅, {a}, {b}, {a,b}} which gives 4 elements in total.
Note that empty set ∅ is always part of the subset of any given set
Question A: The per capita debt would be $43,888.75.
Per capita means the amount per person. To find this amount, we need to take the total debt and divide it by the number of people.
13,561,623 divided by 309 = 43,888.75
For Question B, you will need to have the other CPI value from the table.
Answer: ∠ACB ≅ ∠E'C'D'; translate point D' to point B
Step-by-step explanation:
That is just my best guess.
Anthony ran 5.5 miles each day after school
Let x represent the amount of mile he covered at the park after school. Since he ran 1.5 miles each day before school, the total distance covered each day is:
Total distance covered each day = Distance ran before school + Distance ran after school
Total distance covered each day = 1.5 + x
Since he ran for 4 days in a week, hence:
Total distance ran in a week = 4 days × (1.5 + x)
Total distance ran in a week = 4x + 6
But at the end of the week he ran 28 miles, hence:
4x + 6 = 28
4x = 22
x = 5.5 miles
Hence Anthony ran 5.5 miles each day after school
