Answer:
187.5 pounds are in 3000 ounces
Step-by-step explanation:
Answer:
Step-by-step explanation:I can’t see the opitons but what you would do is subtract 59.50 and 30.Then for the remain number every dollar is 4 people.
Answer:
The population is 300 the sample is the amount of people who responded.
= 300 ⇒300:138
this means sample unsatisfactory
as the sample was less than 50%
Step-by-step explanation:
The population is viewed as 300/570
There are a number of different ways to handle this. One is to target a 100% response rate, although in doing this care has to be taken in how it is achieved to avoid biasing the responses by changing them! By way of a silly example, if I offered everyone who responds to the survey a lifetime’s supply of ice-cream to boost the response rate, and the survey includes questions about future purchases of ice-cream, that may well impact on the answers. Similarly, cajoling employees into completing an engagement survey may have a negative effect on their answers.
Non-response does not always have a negative effect on survey result (there is a large body of research in this area: Curtin, Presser, and Singer 2000 ; Keeter et al. 2000; , and Earl, “The Practice of Social Research”). Anything over 50% is usually sufficient, and over 70% is viewed as a very good response rate. There are a number of reasons for survey non-response:
Awareness (people were not aware of the survey due to communication failure).
Capability (people do not have the knowledge/competence/tools to complete the survey).
Motivation (people are aware and able, but unmotivated/unwilling/refusing).
Answer:
The coefficient is the numerical value in front of the variable so some examples.
Ex: 3x
3 is the coefficient
Ex: 9x²
9 is the coefficient
Ex: x³
1 is the coefficient because in front of the variable there is an imaginary 1 if there is no numerical value in front of the variable.
Ex: -9x
-9 is the coefficient.
