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:
1/4
Step-by-step explanation:
3 red + 6 green = 9 total
P( red) = red/total = 3/9 = 1/3
Now we don't put it back
2 red + 6 green = 8 total
P( green) = green/total = 6/8 = 3/4
P (red, keep,green) = 1/3 * 3/4 = 1/4

3
Step-by-step explanation:
because there are only three pictures
Distribute the negative sign to the 4x and 11 making it 3x+5y-4-4x-11 and combine like terms
