First answer haha~ I think I answered all your questions so far ;)
Answer:
6/21.
Step-by-step explanation:
let the rational number be 2x/7x.
2x + 4 / 7x - 2 = 10 /19
Cross multiply:
19(2x + 4) = 10(7x - 2)
38x + 76 = 70x - 20
96 = 70x - 38x
32x = 96
x = 3.
So the rational number is 2*3/ 7*3
= 6/21.
Answer:
They are skew and will never intersect.
Step-by-step explanation:
see attachment for the missing figure
Lines a and b are skew lines since they are not parallel and they do not intersect. The explanation that they don't intersect is on the grounds that each line is in a parallel plane. Parallel means heading off to the same direction but neither converging nor diverging.
Answer:
Unsure, take a look at the visualisation:

Replace the (dotcom) with ".com" ( links are not allowed :( )
Explanation:
None of the points look as though they are an outlier from the line of linear regression, although (29,62) looks furthest from the line so could be a possible answer although I would probably say there is no outlier.
C = 10d+ 45 ? Hope this helps? Let me know if it’s right or not.
