Answer:
C
Step-by-step explanation:
In this question, we are asked to select which of the options best answer the question.
We proceed as follows;
Using the information given,
Each of the 110 students in a statistics class selects a random sample of 35 Quiz scores
from a population of 5000 scores. They are not given the population mean and standard deviation.
Now, using these data, each student then construct a 90% confidence interval for µ which is the average Quiz score in the population of 5000 students.
By definition, the population mean values will definitely be within the limits of this
confidence interval.
Thus, the correct answer is, Option (c)
Answer:
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
Completed question;
There were approximately 1.6 * 10^11 pieces of mall processed by the United States Postal
Service in 2012. This is about 75% of the number of pieces of mail processed in 2006.
Approximately how many pieces of mail were processed by the United States Postal Service in
2006
Step-by-step explanation:
Let x represent the number of mails processed in year 2006
Given;
Number of mails processed in 2012 N = 1.6 × 10^11
Number of mails processed in 2012 N is about 75% of the number of pieces of mail processed in 2006.
So;
N = 75% of x
N = 0.75x
x = N/0.75
x = (1.6 × 10^11)/0.75
x = 2.13 × 10^11
Approximately 2.13 × 10^11 mails were processed in 2006
The vertex form:

(h,k) - the coordinates of the vertex

The coordinates of the vertex are
(-4,13).
You basically plug in the x in the equation, for example if x = 4 and the equation is y = 2x + 5 you plug in 4 and the equation becomes y = 2(4) + 5. you then multiply and get y=8+5. from here u just add it and u get ur answer
