Steps:
1. Do the point slope form
Y-Y1=m(x-x1)
Y-5=2(x + 6)
Y-5=2x +12
2. Now you add 5 to the number 12
3. Your answer is
Y=2x +17
Answer: its always
Step-by-step explanation:
If a point lies in between two end points of a line then the sum of distance between the points in between is always equal to the whole line.
If A is in between two points B and C then the sum of line segments BA and AC will always equal to the length of BC.
Or BA+AC=BC in all cases whatever be the position of point A between the points Band C.
Always is the right option.
Answer:
4.53
Step-by-step explanation:
Given the data :
4, 5, 10, 11, 15
The mean = 9
The standard deviation of a sample :
s = √[Σ(x - mean)²/(n-1)]
s = √[((4-9)² + (5-9)²+(10-9)² + (11-9)² + (15-9)²) / (5-1)]
s = √(25+16+1+4+36)/4
s = √20.5
s = 4.527
s = 4.53
