Aprofessor at a university ranks subjects based on students' preferences identified through a survey. he ranks science first, mathematics second, and management third. what type of measurement scale has the professor employed? a. nominal b. ordinal c. interval d. ratio

B. Ordinal

Step-by-step explanation:

First we need to identify if the data is qualitative or quantitative. The measurement scale of Qualitative data can be either Nominal or Ordinal while for Quantitative data it would be either Interval or Ratio Level.

In the given case the data is name of the subjects: Science, Mathematics and Management which clearly is Qualitative Data. Now we need to see if the data is at Nominal Level or Ordinal Level.

Data at Ordinal level can be put into some order while data at Nominal Level cannot be put into order. Since the professor is able to rank the subjects based on preferences of students, he is establishing a relation between subjects by putting them in an Order.

Hence, the measurement scale the professor employed was Ordinal.

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

3 1/3 x 2 3/5 = 8 2/3

step-by-step explanation:

just multiply the first number by the second number to get your answer.
