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:
Triangle area is 1/2 bh
So 11.9 is about 12, 7.1 is about 7.
7x12 = about 84 sq, cm
Answer:
20
Step-by-step explanation:
- You can set this up in an algebraic equation:
- .09x=5 which translates to 9% times a variable or unknown number equals 5
- Divide both sides by .09 which turns to 55.5
- Multiply by .36 to find 36% of that number which equals 20
Answer:
x=-4
Step-by-step explanation:
divide 32 by 8 and move the negative sign to the result.
