Answer:
A. positive slope.
Step-by-step explanation:
In the least square linear regression of Y on X, the straight line of best fit is given by,
------------------(1)
[where is the estimated value of Y]
Clearly, here,
Slope pf the line = ---------------------------------(2)
Y- intercept = -----------------(3)
and,
X - intercept = ----------------(4) [putting in (1) and taking the value of X]
So,
since
[since or will result in a degenerate distribution, hence these cases are discarded]
so, correlation coefficient = > 0 implies
A. positive slope. [as evident from (1)]
clearly from (3) and (4) all the other options are false.
Answer:
-14x+6
Step-by-step explanation:
Start off by using the Pythagorean Theorem: a^2 + b^2 = c^2
12^2 + 35^2 = 37^2
144 + 1,225 = 1,369
1,369 = 1,369
If the left side equals the right side than it is a right triangle.
Your answer is: Yes
Have an amazing day and stay hopeful!
