Correlation coefficient is always between -1 and +1. So it cannot be +2.3
Answer:
No
Step-by-step explanation:
Because 0.3 is a decimal and 18 is a whole number.
0.3 = 3/10 which is 30%
Well first, you have to know the distance formula. You plug the coordinates into it and you get the answer.
![\sqrt(-2 + 3) ^{2} + (-2 - 5) ^{2}](https://tex.z-dn.net/?f=%20%5Csqrt%28-2%20%2B%203%29%20%5E%7B2%7D%20%2B%20%28-2%20-%205%29%20%5E%7B2%7D%20)
√1² + -7² = d
d = 7.1
