Answer:
Infinitely many solutions
Step-by-step explanation:
3x-3x-2=-2
3x-3x = 0
0-2= -2
-2 = -2 Which is true, meaning it can be infinitely many solutions

Answer choice D. In order to find the r value, you need to find the degrees of freedom (df). df = n -2. In this case then the degrees of freedom is 9 (11 - 2). Now you use the df, the significance value (also known as p-value), and the critical value table (search it up if you don’t have one) to find that with a df of 9 and a probability value of 0.01, the r = 0.735.
The reason for why the answer is not “A” is due to the fact that we’re finding all of the possible r values, we are not a evaluating r to see whether or not it is significant.
