Answer:
Methods of obtaining a sample of 600 employees from the 4,700 workforce:
Part A: The type of sampling method proposed by the CEO is Convenience Sampling.
Part B: When there are equal number of participants in both campuses, stratification by campus would give a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender. Another method to ensure that stratification by campus gives a more precise approximation of the proportion of employees who are satisfied with the cleanliness of the breakrooms than stratification by gender is to ensure that the sample is proportional to the proportion of each campus to the whole population or workforce.
Step-by-step explanation:
A Convenience Sampling technique is a non-probability (non-random) sampling method and the participants are selected based on availability (early attendees). The early attendees might be different from the late attendees in characteristics such as age, sex, etc. Therefore, sampling biases are present. All non-probability sampling methods are prone to volunteer bias.
Stratified sampling is more accurate and representative of the population. It reduces sampling bias. The difficulty arises in choosing the characteristic to stratify by.
Answer: 96
Step-by-step explanation:
Simply multiply the first question by 12 to get 2x+8y=96

The answer to this question would be: 5 second
In this question, you are given the initial distance (300ft), car velocity(48ft/s) and the final distance(60ft). You are also given the equation to calculating the distance, so this question should be easier. The question is when the time where the distance is 60 ft. So the answer would be:
distance= 300-48t
60 = 300ft- 48t
48t= 300- 60=240
t= 5
Answer: D. 15
Step-by-step explanation:
Given : The revenue each season from tickets at the theme part is represented by 
.
The cost to pay the employees each season is represented by 
.
From the given graph , we can see that at 4th season, the profit = 15
Hence, the estimated profit after four seasons. =15
9.81 times 10 to the -5th power
