(CO 1) You need to study the satisfaction of customers of a specific restaurant. You decide to randomly select a few tables and talk to everyone at those selected tables. This would most closely describe which type of sampling technique
Answer:
Cluster
Step-by-step explanation:
The Cluster sampling technique involves choosing a population to be studied and dividing it into clusters that truly represent the population, through random sampling. In the question above, all the customers in the restaurant represent the population to be studied. Since all the customers can not be interviewed at that time, clusters, in the form of tables are formed through random sampling.
It is necessary for the researcher to ensure that the customers in all the table clusters truly represent the population.

a. Evaluate: h (g(1/2))
b.
Find hfx)
Answer:
f(-1) = (-1)^3 + 2 = -1 + 2 = 1
h(f(-1)) = 3(1) = 3
g(h( f ((–1))) = (3)^2 – 1 = 9 - 1 = 8

3.) An attorney charges a fixed fee of $250 for an initial meeting and $150 per hour for all hours
worked after that. The equation represents his total fee is y=150x + 250. Find the value of y
for the following hour(s) (x) that he has worked: {0, 1, 5, 10, 15, 303
Answer:
A → C = 150h + 250 ( where C is charge )
B → C = 175h + 150
for 26 hours
A → C = (150 × 26 ) + 250 = 3900 + 250 = $4150
B → C = (175 × 26 ) + 150 = 4550 + 150 = $4700
Attorney A is cheaper for 26 hours, thus better deal
Equate the 2 equations to find hours they charge the same
175h + 150 = 150h + 250 ( subtract 150h from both sides )
25h + 150 = 250 ( subtract 150 from both sides )
25h = 100 ( divide both sides by 25 )
h = 4 ← number of hours when charges for both are equal
Attorney A becomes a better deal at 5 hours

What is an angle?In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.
here, we have,
we know that,
Sum of all angles in a triangle is 180.
The angle PNO will hence be:
180 - 38 - 39 = 103 degrees.
The angle PNO + angle x = 180 degrees (straight line)
So 103 + x = 180,
therefore x = 180 - 103 = 77.
Which is also greater than 38,
so x > 38 is also correct.

Step-by-step explanation:
A newsletter publisher believes that 64d% of their readers own a Rolls Royce. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.020.02 level of significance, the testing firm decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim
Answer:
Step-by-step explanation:
The null hypothesis
[tex]H_o:p=0.64[/tex]
The alternative hypothesis
[tex]H_1:p \neq 0.64[/tex]
At 0.02 level of significance,
the testing firm rejects the null hypothesis.
This implies that the rejection of the null hypothesis shows that there is sufficient evidence to reject a newsletter publisher who believes that 64% of their readers own a Rolls Royce.
