Hello! :)
P (a or b) means
P (a+b)
So the blue side and the red side of the diagram have students so add them up:
3+2=5
Then the ratio
blue and red/total number of students
5/10
(10 students)
So simplify:
1/2
Hope I helped and answered in time!
Good luck!

Answer:
145$ is the markup price i think
Step-by-step explanation:
100$+ 45%=x
100/100%=1
45%*1=45
100$+45$= 145$
Answer:
I'll show you the dilution of point A and you can figure out the answer
Step-by-step explanation:
not sure what level you are in at school. Since the dilation is about the origin, it very straight forward. Basically you multiply the scale factor by each coordinate of a given point.
so the dilated point for A is in the x direction 1x6 and in the y direction 2x6, resulting in A'= (6,12).
do this for each point and you will have the answer
2e = 4e - 16
*subtract 4e from both sides
-2e = -16
*divide both sides by -2
<u><em>e = 8</em></u>
I'd prefer 5/7 because both numbers would be in decimals and you dont need decimals
