Suppose you went on a vacation in a different country and returning to your school. What is the level of measurement of the variable: the class in which you are travelling

Ordinal

Step-by-step explanation:

When dealing with categorical variables who doesn't permit mathematical or numerical evaluation of values or inputs, the ordinal variable atleast gives a method of scaling which allows us to rank variables on terms of importance, magnitude and so on. Such that the even though we can't measure the difference between the variables, we can tell that one is much better, important or higher in hierarchy than the other. Such is the categorical variable, of class when traveling. This could be Economy, Business, First class.

The Economy class is the lowest, followed by Business class then the First class. Here, there is an order or rnak in the classes but not measurable.

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3

i believe that the answer is

b. y-1=-2(x-4)

hope this !
