Answer:
I think it is 37.5°.
Step-by-step explanation:
The answer is B)x+y=y+x.
This is just changing the order of the numbers to get the same equation....\
So for example if I have 2+7 and I use the property of addition It would give me 2+7=7+2.
Pls mark brainliest if this helped!
Answer:
d. H0: vs.
Step-by-step explanation:
A hypothesis is defined as "a speculation or theory based on insufficient evidence that lends itself to further testing and experimentation. With further testing, a hypothesis can usually be proven true or false".
The null hypothesis is defined as "a hypothesis that says there is no statistical significance between the two variables in the hypothesis. It is the hypothesis that the researcher is trying to disprove".
The alternative hypothesis is "just the inverse, or opposite, of the null hypothesis. It is the hypothesis that researcher is trying to prove".
On this case the Management try to determine if there is a difference in the average investment/quad between using electricity and using gas. So this needs to be on the alternative hypothesis. And the complement of the alternative hypothesis would be on the null hypothesis.
Null hypothesis :
Alternative hypothesis:
Or equivalently:
Null hypothesis :
Alternative hypothesis:
Other important thing is that on the alternative hypothesis we never can have the symbol equal.
So on this case the best options is:
d. H0: vs.
Question 11 :
the equations are :
now, let's graph the lines ~
As you can see in the attachment, The lines coincides each other, so the equations are :
(x,y)
Quartile 1/original coordinates (x,y)
Quartile 2 (-x,y)
Quartile 3 (-x,-y)
Quartile 4 (x,-y)
use this to move a shape on the graph
the degree of rotation of a shape on a graph depends on where the shape starts and ends
