The variance of the dataset is the square of their standard deviation

The variance of the dataset is 0.307

<h3>How to determine the variance?</h3>

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:

\sigma^2 = \frac{\sum(x - \mu)^2}{n}

So, we have:

\sigma^2 = [(0.0625 - 0.578125)^2 + (0.25 - 0.5781250^2 + (0.5 - 0.578125)^2 + (1.5 - 0.578125)^2]/4

Evaluate

\sigma^2 = 1.2294921875/4

Divide

\sigma^2 = 0.30737304687

Approximate

\sigma^2 = 0.307

Hence, the variance of the dataset is 0.307

0= (2y-1) (8-y) Let the y = u and y = d be unique solutions to the equation above. What is the value of u ⋅ d?
mariarad [96]

Answer:  The value of u · d = 4

Explanation:  

(2y -1) = 0 , 2y = 1  ,  y = 1/2 .  u = 1/2

(8-y)=0  y = 8  d = 8

Substitute values for u·d   1/2 · 8 = 4
