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.

24 packs (2 for 9):
9/2=4.5 per pack
4.5/24=.1875 (round to .19 per can)
12 packs (4 for 10):
10/4=2.5 per pack
2.5/12=.2083 (round to .21 per can)
12 packs (3 for 9):
9/3=3 per pack
3/12=.25 per can.
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
WHAT ARE YOU TRYING TO FIGURE OUT WITH THIS ONE HOW MANY MILES IT FLEW TOTAL IT WOULD BE 24 TIMES 6 TO EQUAL 144
1. 24 students and 3 absent
24-3=21
so 21 student goes
2. 21 students divided by the 3 vans
equals to 7
so 7 student went in each van
