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:
A. 2.2402
Step-by-step explanation:
4x² - 100 = 0
<u> + 100 + 100</u>
<u> 4x²</u> = <u>100</u>
4 4
x² = 25
x = <u>+</u>5
4(5)² - 100 = 0
4(25) - 100 = 0
100 - 100 = 0
0 = 0
4(-5)² - 100 = 0
4(25) - 100 = 0
100 - 100 = 0
0 = 0
The roots of the equation is positive or negative 5.
Answer:
d
Step-by-step explanation:
Rewrite in slope intercept form (move 5x to the right, divide both sides by 2, and reorder the terms)
Answer:
B
Step-by-step explanation:
all you need is to solve the first term
2x² - (-3x²) = 5x² ,
b is the only answer with 5x² in it
