Answer:
For a line of best fit, it doesn't nessesarily have to land on a point, it just has to be in between them or on them whichever way you choose to do it. And also your second question, yes it is correlation if it lines up with the line and not somewhere else or if there are so many dots that they don't really form a line then it isn't a correlation.
Hope this helps!
Answer:
B. 12.16 inches
Step-by-step explanation:
Triangle MNP has two sides given as length 5 (MN) and 10 (PN). The third side (MP) must be longer than 10* and less than 10+5=15. There is only one answer choice in that range: 12.16.
__
If we call the point of intersection of the diagonals X, then we know that NX = 8/2 = 4, and we can use the Pythagorean theorem to find MX and PX.
MX² +NX² = MN²
MX² + 4² = 5²
MX = √(25 -16) = 3
__
PX² +NX² = PN²
PX² + 4² = 10²
PX = √(100 -16) = 2√21 ≈ 9.1652
Then ...
MP = MX +PX = 3 +9.1652 = 12.1652 ≈ 12.17 . . . . . matches selection B
_____
* The argument for the upper limit of MP comes from the triangle inequality. The argument for the lower limit comes from the observation that angle NMP is smaller than angle MNP, so side PN must be shorter than side MP. That is, MP must be greater than 10 inches.
