these chords are congruent because the radius of the circle are perpendicular to the them
so we can find EF by making an equation:
so EF is = 3(15)+5=50
good luck

The variance of a distribution is the square of the standard deviation
The variance of the data is 2.2
<h3>How to calculate the variance</h3>Start by calculating the expected value using:
So, we have:
This gives
Next, calculate E(x^2) using:
So, we have:
The variance is then calculated as:
So, we have:
Approximate
Hence, the variance of the data is 2.2
