Answer:
<u>Skills needed: Angle Geometry</u>
Step-by-step explanation:
1) First, let's see what we should know prior to solving.
---> We have to find the value of , and looking at that diagram, we have to create an equation.
---> The angle measure of a straight line is 180 degrees, otherwise known as a straight angle (a straight angle is 180 degrees).
---> When you add , you can set that sum equal to 180. This is because the two angles marked
added together make a straight line, which is a straight angle.
(Note: In geometry, ONE OF THE THINGS WE CAN ASSUME is that there is a straight line there.)

2) Now, the equation would be:
--> Combining
and
(3+3 = 6)
--> Dividing by 6 on both sides, to get
by itself.
--->
is 30, so
is equal to 30.

Answer: A. H0: Mean= 5 and Ha: Mean is not equal to 5.
Step-by-step explanation:
Definitions:
- Null hypothesis
is a statement describing population parameters according to the objective of the study. It takes "≤,≥,=" signs.
- Alternative hypothesis
is a statement opposite to the null hypothesis elaborating population parameters according to the objective of the study. It takes ">, <, ≠" signs.
Given: The diameter of a spindle in a small motor is supposed to be 5.8 millimeters.
If the spindle is either too small or too large, the motor will not work properly. so, Mean diameter ≠ 5.8 to work correctly.
i.e.
So,
The required null and alternative hypotheses:
H0: Mean= 5 and Ha: Mean is not equal to 5.
