Answer:
<em>( 4, 11 ) , ( - 4, 27 ) </em>
Step-by-step explanation:
f(x) = x² - 2x + 3
f(x) = - 2x + 19
x² - 2x + 3 = - 2x + 19
x² - 16 = 0
( x + 4 )( x - 4 ) = 0
= - 4
= 4
f(x) = 
= - 2( - 4 ) + 19 = 27
= 27
f(x) = 
= - 2( 4 ) + 19 = 11
= 11
<em>( 4, 11 ) , ( - 4, 27 )</em>
Answer: 0.8022 | This is your answer
Step-by-step explanation:
Well this question is a bit baud but I will try to answer my best.
To find the difference of any number you just need to subtract.
So a-b=c | c is your difference.
So in this problem 1-0.1978 would equal 0.8022

Step-by-step explanation:
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.
