The variance of the dataset is the square of their standard deviation
The variance of the dataset is 0.307
How to determine the variance?The dataset is given as;
0.0625 0.25 0.5 1.5
Calculate the mean using:
μ = Sum/Count
So, we have:
μ = (0.0625 + 0.25 + 0.5 + 1.5)/4
Evaluate
μ = 0.578125
The variance is then calculated using:
[tex]\sigma^2 = \frac{\sum(x - \mu)^2}{n}[/tex]
So, we have:
[tex]\sigma^2[/tex] = [(0.0625 - 0.578125)^2 + (0.25 - 0.5781250^2 + (0.5 - 0.578125)^2 + (1.5 - 0.578125)^2]/4
Evaluate
[tex]\sigma^2[/tex] = 1.2294921875/4
Divide
[tex]\sigma^2[/tex] = 0.30737304687
Approximate
[tex]\sigma^2[/tex] = 0.307
Hence, the variance of the dataset is 0.307

For this question, we are concerned with the movement of an object along a path in the plane. we are assuming that the plane is a coordinate plane and the object starts at the point. as the object moves along the path, each point on that path has two coordinates. the coordinates depend on the distance traveled along the path. let us call this distance s, the length of the path from the origin to a point p on the path.
The value of s that will be able to yield the coordinate (4, 3) is 5.
How to find the value?From the information given, in order to find the value of s, we'll use the Pythagoras theorem. This goes thus:
OA = ✓4² + ✓3²
OA = ✓(16 + 9)
OA = ✓25
OA = 5
Therefore, value of s that will be able to yield the coordinate (4, 3) is 5.
