Answer:
The correct value is t* = 2.797.
Step-by-step explanation:
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 25 - 1 = 24
99% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 24 degrees of freedom(y-axis) and a two-tailed confidence level of . So we have T = 2.797.
Answer:
Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-7).
Therefore the co-ordinate of the point on the line segment from (-9,-1) to(-9,-10) into a ratio internally is (-9,-19).
Step-by-step explanation:
Given points are (-9,-1) and (-9,-10)
If a point divides the line segment by joining two points (x₁,y₁) and (x₂,y₂) into a ratio m:n internally.
Then the point of the coordinate is .
If a line segment is externally divided into a point by joining two points (x₁,y₁) and (x₂,y₂) with m: n ratio.
Then the point of the coordinate is .
Internally
The co-ordinate of the point is
Externally
The co-ordinate of the point is
= (-9,-19)
