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:
80 degrees
Step-by-step explanation:
Sum of the interior angles of a triangle = 180
a + 50 + 50 = 180
a = 80
<h2><u>
Here is the reference No funny stuff XD</u></h2>
Since it is given that 4/5 mile is equal to 1/2 inch, what we will be looking for how many inches will there be for 1 mile. 5/5 mile = 1 mile.
This is how it would look like.
1/2 inch.... x inch
----- = -----
..4/5 mile ...... 1 mile
Next, we cross multiply:
(1/2)1 = (4/5)x
Then divide both sides by 4/5. so we get
x = 0.025 inch
and that is 1/40 inch. Therefore, 1 mile is 1/40 inch. Hope this helps.
