Naddik [55]

Answer: D. Ordinal

Step-by-step explanation:

There are four levels of measurements scales of a variable :-

  1. Nominal scale : Used for categorical data on the basis of the characteristic like sex, religion color, etc.
  2. Ordinal scale : Used to order the attributes as per their ranks such as First ,Second , Third and so on.
  3. Interval scale : Used when the difference between any two values can be calculated and has meaning such as Fahrenheit scale to measure temperature.
  4. Ratio scale : It accommodates all the qualities of the 3 measures and in addition a "true zero" point. For example : Age.

<em>Positions of runners in a race comes in ordinal scale because we need to order them with their respective rank</em>.

So, the correct option is D. Ordinal

Eric's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Eric $5.50 per pound, and type B
AlekseyPX

115.2 pounds of type A coffee were used.

<h3>What is the solution of the equation?</h3>

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have LHS = RHS (left hand side = right hand side) in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved.

Let the number of pounds of type A coffee be x and the number of pounds of Type B coffee be y.

According to the question, the equations are,

5.50x + 4.40y = 762.30

x = 4y

So, the solution of the equation is obtained as follows:

5.50(4y) + 4.40y = 762.30

26.40y = 762.30

y = 762.30/26.40

y = 28.8 pounds

x = 4*28.8 = 115.2 pounds
