Answer: r = -0.64
Step-by-step explanation:
The correlation coefficient is a measure of the strength of the linear relationship between two variables and is denoted by r. Values between 0.3 and 0.7 indicate a moderate positive (negative) linear relationship .
Values between -0.3 and -0.7 indicate a moderate negative linear relationship .
The only value of r in the option is r= -0.64 lies in given interval of moderate negative linear relationship .
Therefore, c is the right answer.
Answer:
11/12
Step-by-step explanation:
2/3+1/4
8/12+3/12= 11/12
To get the answer, do 30,00 / 8
after dividing that you will get the answer 3,750
The answer is 162 81pi/2
Hope this helps!
the area is (1/2) x pix 9^2 = 81pi over 218.9=162162-81pi over 2
For the first one y= -1 but idk how to do the others sorry
