Answer

7. 30

8. 54

Step-by-step explanation:

For 7 do 2x+3x=90 because it is a right angle

then solve for x and get 15

to get the angle you are looking for multiply 2 by 15

and get the answer 30

For 8 to find the value of x you would need to...

add (4x+6) + (11x-6)= 180 because 180 is a straight angle.

Then simply solve for x and get 15x=180 which equals 12

The to get the angle you plug it in to (4x+6) and get the answer 54

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.
