The number of degrees of freedom is 29.

<h3>What is degree of freedom?</h3>

A degrees of freedom inside a statistical method describe how many values in a computation can vary. The degrees of freedom of chi-square tests, t-tests, and even more complex f-tests can be calculated to assist confirm their statistical validity.

These tests are frequently used to have a data with the data that would anticipated to be obtained if a given hypothesis were followed.

Degrees of Freedom Formula:

The statistical formula for determining degrees of freedom is straightforward. It is written as follows: degrees of freedom are the number of values in such a data set minus one.

df = N-1

Where N denotes the total number of items in the data collection (sample size).

Now according to the question,

Its degrees of freedom will be determined using the method df = N-1:

df = 30-1 = 29 appears in this case.

This means that in this data collection, three integers can vary as long even as mean remains 20.

B is the midpoint of AC and D is the mid point of CE solve for x given BD=3x + 5 and AE= 4x+20
Elena L [17]

Answer:triangle BCD is similar to triangle ACE (side, angle C, side)

AC = 2 BC

therefore AE = 2 BD

therefore

4x+20 = 2 (3x+5) solve that
