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:
Second option: B and C
Step-by-step explanation:
A is the product of 4x and -2x: A=(4x)(-2x)→A=-8x^2 (x^2)
B is the product of 4x and 3: B=(4x)(3)→B=12x (x^1)
C is the product of 1 and -2x: C=(1)(-2x)→C=-2x (x^1)
D is the product of 1 and 3: D=(1)(3)→D=3 (constant)
Then, the like terms are B and C
The difference between properties of equality and properties of inequality that you need to take into account when you are solving equalities and inequalities is the effect that some operations have on the sign.
1) The multiplicative property of equality permits you to multiplicate both members (sides) on an equality times a factor and the equality will remain. But in an inequality, while the factor is positive the inequality will remain but when the factor is negative, the sign of the inequality will change.
2) The same is true about the division property:
3) When you use othe functions like absoulte value and square root you will also need to be attentive of the effect of the function on the sign of the equality,.
