Determine whether the variable is qualitative or quantitative. Explain your reasoning. favorite city
Fofino [41]

Answer:

Qualitative variable.

See explanation below.

Step-by-step explanation:

In research we have two types of variables: the quantitative and the qualitative variables.

  1. A quantitative variable is a variable that is a number, for example: age, height, number of years of school. These type of variables are only numbers.
  2. A qualitative variable is a variable that is not a number but rather a category of data. For example: your name, your gender, your favorite food. All these examples are not numbers but categories.

In this example we are asked about our favorite city, we can see that the possible answers for this question are: Dallas, Seattle, Washington, Paris, etc.. these are not numbers so therefore this is an example of qualitative variable.

Write an equation in standard form of the line that passes through (0,5) and has the slope m=−2
Ray Of Light [21]
Y=-2x+5
The standard form is y=mx+b, since m is the slope you would put -2 in substitute for it and since (0,5) has a zero as the x and a number as the y that gives you the b which is the y-intercept.

The length of a rectangular field is 7 m less than 4times the width. The perimeter is 136 m. Find thewidth and the length of the
OlgaM077 [116]

Length (L): 4w - 7

width (w): w

Perimeter (P) = 2L + 2w

               136 = 2(4w -7) + 2(w)

               136 = 8w - 14 + 2w

               136 = 10w - 14

               150 = 10w

                 15 = w

Length (L): 4w - 7   = 4(15) - 7   = 60 - 7   = 53

Answer: width=15 m, length=53 m
