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.
Answer
D. -3x + 4(2x-6) + 5
Step-by-step explanation:
-3x has nothing attached to it so leave it alone
4 times 2x equals 8x and 4 times -6 equals -24
add 5
8x-3x=5x
-24 + 5 = -19
5x - 19
