Answer:
a. Identify the population of interest in this study.
- all the population of the country
b. Identify the sample for the study.
- 50 adults (the ones that were surveyed)
c. Identify the parameter of interest in the study.
- the parameter of interest is the people that believe that coffee shops are overpriced
d. Find and interpret a 95% confidence interval for the parameter of interest.
z score for a 95% confidence level = 1.96
margin of error (E) = z score x √{[0.4(1 - 0.4)] / 50} = 1.96 x 0.069282 = 0.13579
95% confidence level interval:
0.4 - 0.13579 = 0.26421
0.4 + 0.13579 = 0.53579
- 95% confidence interval (0.26421 , 0.53579)
Answer:
The correct answer is $30
Step-by-step explanation:
36-6=30
8x+6=54
subtract 6 from both sides
8x+6-6=54-6
8x=48
x=6
which of the following sets represents the range of the function shown? {(–3, 4), (5, 11), (9, –1), (10, 13)} a: {–3, 5, 9, 10}

The domain is all the x values and the range is all the y values.
So we are looking for range....all the y's.
So look at ur function...list all ur y's...(4,11,-1,13) arrange them in order :
(-1,4,11,13) <===ur range (y values)
Answer and Explanation:
To prove : The square of any even number is always a multiple of 4.
Proof :
The even numbers is defined as number end with 0,2,4,6,8 or the even number are multiple of 2.
Let the general even number be '2n'.
Squaring the number 
As 4 is the multiple of n².
So, If we square any even number it is always a multiple of 4.
For example,
Hence proved.
