Answer: 
Step-by-step explanation:
I assume that you need the new coordinates of the point after the rotation centered at the origin.
For this exercise it is important to remember the definition of "Rotation".
A Rotation is defined as a transformation which a figure is rotated about a fixed point known as "Center of rotation".
The figure before the transformation is called Pre-Image and the figure obtained after the transformation is called "Image".
The 180 degree rotation about the origin Rule states that:
→ 
Therefore, knowing that the given point (5,4) is rotated 180 degrees clockwise about the origin, you can conclude that its Image is:

(50+ b)5
= 5* (50+ b) (commutative property)
= 5* 50+ 5* b (distributive property)
= 250+ 5b
= 5b+ 250
The final answer is 5b+ 250.
Hope it helps.
Answer:
Option d) Both (a) and (c)
Step-by-step explanation:
ANOVA
- It stands for analysis of variance
- It is used to check difference in mean of three or more groups.
- It can also be used to check the difference between mean of groups.
- It can also be used to check the difference between medians of groups.
- There are many types of ANOVA test: one way, two way, etc
Thus, the correct answer is
Option d) Both (a) and (c)
