Answer:

Yes.

Step-by-step explanation:

This is a statistical question because a statistical question is a question that can be answered by collecting data that vary. The question that you provided would have different answers from different people.

Another example of a statistical question could be: "How old are the students at my school?" This would be statistical because once again, the ages will vary from different people.

If x = -3 and y = 4x - 1, then y equals what number

Masteriza [31]

$\huge\text{Hey there!}$

$\large\textsf{y = 4x - 1}$

$\large\text{If x= -3, then substitute it into the given equation}$

$\large\textsf{y = 4(-3) - 1}$

$\large\textsf{4(-3) = \boxed{\bf -12}}$

$\large\textsf{y = -12 - 1}$

$\large\textsf{-12 - 1 = y}$

$\large\textsf{-12 - 1 = \boxed{\bf -13}}$

$\boxed{\boxed{\large\textsf{Answer: \huge \bf y = -13}}}\huge\checkmark$

7w−(2+w)=2(3w−1)

Llana [10]

Simplify brackets

(7w - 2 - w = 2(3w - 1)

simplify 7w - 2 - w to 6w - 2

(6w - 2 = 2(3w - 1)

Expand

(6w - 2 = 6w - 2)

Since both sides are equal, there are infinitely many solutions

Answer: C) INFINITELY MANY
