Answer:
To find the mean of a data set you have add all the values together and divide by the number of values in the set. The result is your mean
Step-by-step explanation:
Such as finding the mean of 1, 2, 4, 7, 9 as an example
Adding those numbers together you get 23. You then divide 23 by 5, given that there are 5 values above. 23/5 is 4.6. The mean would be 4.6
In the right triangle, the longest side is the hypotenuse.
Let α be the angle opposite to the side with a length of 12 units, <span>then according to the Law of sines:

In a triangle, the three interior angles always add to 180° ⇒
third angle = 180 - 90 - 67 = 23°
Answer:
67° and 23° (to the nearest degree).
Answer:The formula y=kxn y = k x n is used for direct variation. The value k is a nonzero constant greater than zero and is called the constant of variation.
