For this case we have that by definition, the subtraction property of equality establishes that having an equality, any number that is subtracted from one side of it, must be subtracted from the other side.

We have:

x = 2

So, for it to be fulfilled:

x + 20 = 22

We must subtract "20" on both sides of the equation:

x + 20-20 = 22-20\\x = 2

<u>Answer:</u>

<u>A</u>dditive property of equality

<u>Step-by-step explanation:</u>

We are given the following expression(s) and we are to determine and explain the property of equality used to arrive to conclude the following:

<em>if x=2 then x+20=22</em>

Its the additive property of equality which is used here to conclude that x + 20 = 22 if x = 2.

According to this additive property of equality, the equality is true if same amount is added to both sides of an equation.

When we reject the null and the null is true, we have a made a _________ __________.
nydimaria [60]

When we reject the null and the null is true, we have a made a type I error

The null hypothesis in statistics states that there is no difference between groups or no relationship between variables. It is one of two mutually exclusive hypotheses about a population in a hypothesis test.

null hypothesis is denoted as H₀

Reject the null hypothesis when the p-value is less than or equal to your significance level. Your sample data favor the alternative hypothesis, which suggests that the effect exists in the population. When you can reject the null hypothesis, your results are statistically significant.

when the p-value is greater than your significance level, you fail to reject the null hypothesis.

Sometimes , we reject our null hypothesis even when its true

there we made a type I error in hypothesis
