The area of a circle with a Diameter of 10 is 78.54
Given:
The two points are (-1,10) and (2,4).
To find:
The equation of line which passes though the given points.
Solution:
If a line passes through two points, then the equation of line is

The line passes through (-1,10) and (2,4). So, the equation of line is




Using distributive property, we get

Adding 10 both sides, we get


Therefore, the required equation of line is
.

It is rounded to 3.9 I think
Answer:
ONE SOLUTION
Step-by-step explanation:
When two points on a line are given, the equation of the line is given by the formula:

where
and
are the points on the line.
Here, the first set of points are:
and
.
Therefore,
and
.
The line passing through this is given by:


∴ 2x + y - 1 =0
Now, for the second line, the points are:
and
.
Therefore, 

∴ 2x - y + 2 = 0
Now, to determine the number of solutions the two equations have, we solve these two equations,
Adding Eqn(1) and Eqn(2) we get:
4x = -1

And
.
Since, we arrive at unique values of 'x' and 'y', we say the lines have only one unique solution.
Answer:

Step-by-step explanation:
We are given the following in the question:
The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.
This will be stated by the null hypothesis.

It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.
This will be stated by the alternate hypothesis.

The parameter for the given hypothesis is standard deviation,
.
