Answer:
The "df" stands for "degrees of freedom", and represents the number of independent observations in a set of data.
Its value in this case is df=32.
Step-by-step explanation:
The sample is of size n=33.
As we do not know the population's standard deviation, we use as estimate the sample's standard deviation. Because of this, we use the t-statistic in place of the z-value.
The "df" stands for "degrees of freedom", and represents the number of independent observations in a set of data (the data in this case is the sample of 33 video games).
In one-sample tests, the degrees of freedom are calculated as:
Answer:
The next 3 numbers to the given pattern of integers is -2,-1,-1,0,-1,1,-2 are 3,-5,8
Step-by-step explanation:
Given pattern of integers is -2,-1,-1,0,-1,1,-2
To find their next 3 numbers of the given pattern :
Let 




Therefore 



Therefore
Similarly we have
,
,
The general form to the given pattern is
for 
Therefore to find the
Put n=8 in 




Put n=9 in 




Put n=10 in 




Therefore the next 3 numbers are 3,-5,8
Answer:
33x-6x(square)-45
Step-by-step explanation:
(2x-5)(9-3x)
= 2x(9-3x) + -5(9-3x)
= 18x-6x(square) - 45+15x
= 33x-6x(square)-45
Answer:
y = x -7
Step-by-step explanation:
y2 - y1 / x2 - x1
-5 - (-2) / 2 - 5
-3/-3
1
y = x + b
-2 = 5 + b
-7 = b
y = -7
y = x -7
