Answer:
<u>Use Two sided t-test</u>
<u>Step-by-step explanation:</u>
Note that, there are other tools to test for significant difference such as simple regression or multiple regression<em> but when comparing the results of two groups in terms of which is higher or lower</em>, then a two sided t-test would be best appropriate.
Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
Answer:
answer is also 60.
Step-by-step explanation:
Since angle 2 is also 60 degrees, angle 6 will also be 60 degrees.
The points represented are:

The domain is the set of all the inputs, i.e. the set composed by the x-coordinates of these points.
The range is the set of all the outputs, i.e. the set composed by the y-coordinates of these points.
This relation is a function, because you never map two outputs for the same input (i.e. you don't have two points with the same x-coordinate, but different y-coordinates).

Answer:
P=9h
Step-by-step explanation:
Since Teresa makes 9 dollars for each hour of work, we can say:
9 dollars/1 hour.
Her total pay will be on one side of the equation:
p=
Since we do not know how many hours, we put the variable ‘h’ as it says in the problem in the hour section:
h hours
Every hour, she makes 9 dollars. Every ‘h’ hour, she makes 9xh or 9h dollars since you multiply the amount of money you get each hour by the number of hours. For example, if she worked 2 hours, you multiply 2x9 to get 18 dollars, which is what she earned in 2 hours.
p=9h
