X = 5. Using the pythagreom theorem, a²+b²=c², to solve x we put in the numbers into the equation getting a²+12²=13². Then solve for a. a²=25, 5·5=25, a=5 which means x=5.
Dear you need to first do the math of each side of the inequality. If the negative number is like -25 and -5, the greater one is -5. The -25 would be least. < means it’s not equal so that an open circle. It’ll look like this, o. If it has the line underneath then it’s equal to the number. It would be a closed circle like this, •. Not sure if that’ll help.
If the correlation coefficient is 0, then there isn't a linear relationship between x and y. Another possible relationship (such as an exponential or quadratic) one could be possible, but it depends on the scatter plot given.
