Answer:
The sample proportion denoted 
, is given by the formula 
, where x is the number of individuals with a specified characteristic in a sample of n individuals.
When we want to estimate the real population proportion 
we use as estimate the sample proportion, given by 
. Where:
x is the number of individuals with a specified characteristic in a sample
n represent the sample size of individuals selected.
Step-by-step explanation:
For this case we can complete the phrase like this:
The sample proportion denoted , is given by the formula , where x is the number of individuals with a specified characteristic in a sample of n individuals.
When we want to estimate the real population proportion we use as estimate the sample proportion, given by . Where:
x is the number of individuals with a specified characteristic in a sample
n represent the sample size of individuals selected.
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.

Answer:
The answer to your question is Area = 9 3/8
Step-by-step explanation:
Data
length = 3 3/4 cm
width = 2 1/2 cm
Process
1.- Write the equation of the Area of a rectangle
Area = length x width
2.- Convert the values to improper fractions
3 3/4 = (12 + 3)/ 4 = 15/4
2 1/2 = (4 + 1) / 2 = 5/2
3.- Substitution
Area = (15/4)(5/2)
4.- Simplification
Area = 75/8
5.- Convert to a mixed fraction
9
8 75
3
6.- Result
Area = 9 3/8
