Answer:
2, 4, and 6
Step-by-step explanation:
Supplementary angles are angles that add to 180°.
We can see that the angles that make a straight line/straight angle with ∠7 are supplementary to it, because a straight line is 180°.
Those numbers would be be 2, which equals to 4, which equals to 6 and also 8, but that number isn't one of the answers
2,4, and 6

Answer:
I don't understand the question
Answer:
D. <
Step-by-step explanation:
-17 is less than -1. Think of it as going down stairs. Who is lower? The person 17 steps down or the person 1 step down. 17 steps down.
-17 < -1
These are the multiple choice options to the question
A. The difference observed would most probably arise by chance.
B. The difference observed would rarely arise by chance.
C. There was a very small difference observed.
Answer:
The observed difference would rarely occur by chance
Step-by-step explanation:
When we talk about something being statistically significant, what we are saying is that it rarely occurs by chance at a given level of significance. The existing data gives us the correct results to a great extent.
We are told in this question that those that are enrolled in health and safety class are more aware of the subjects that affect the health and safety. Now the results have shown that this is true indicating that a difference exists. Therefore it is statistically significant.
For this question the hypothesis is
H0: μ1 - μ2 = 0(no difference)
H1; μ1- μ2 is not equal to 0. (Difference exists)
We reject h0 and accept that there is a difference hence it is statistically significant.
