Answer:

A) The brand of cars driven by Harvard instructors

C) The types of plants growing in yellowstone  

Step-by-step explanation:

Categorical and numerical variables:

  • Numerical data can be expressed with the help of numerical.
  • Categorical data cannot be expressed by numerical.
  • They do no have any particular value.
  • They are the non-parametric data.
  • Categorical data are also known as qualitative data.

A) The brand of cars driven by Harvard instructors

Since the brands cannot be expressed in numerical, it is a categorical variable.

B) The age of randomly selected biology students.

The age of student are expressed in whole numbers or decimals. Thus, it is a numerical data.

C) The types of plants growing in yellowstone

Again, the type of plants cannot be expressed with the help of numerical. Thus, it is a categorical variable.

Blizzard [7]

Hi!

(-3)(5)+10

-15+10

=-5

<u>Explanation: </u><u><em>This question is about math, and this lesson is about order of operations. I will give you a hint. You had to used PEMDAS, P-Parenthesis should be go first, E-Exponents, M-Multiply, D-Divide, A-Add, and S-Subtract. If you use multiply, divide, add, or subtract it should go left to right. First, you had to multiply and divide should go left to right. And it gave us -15+10.  And finally, you should add and subtract by left to right. And it gave us -5 is correct answer. Hope this helps! Thank you for posting your question at here on Brainly. And have a great day. -Charlie</em></u>

Which two numbers add up to -19 and multiply to make 35
iris [78.8K]

x+y = -19
x*y  = 35

x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437
