Answer:
D.
Step-by-step explanation:
Because all of the numbers are positive so you would go over right on the x-axis and go up on the y-axis for all of the numbers. Pull up on the internet a coordinate plane and plant the points on the line.

Answer:
Step-by-step explanation:
<u>Given:</u>
- 40% of students passed in Maths only
- 30% passed in Science only
- 10% students failed in both subjects
- 200 students passed in science
Let the total number of students is x.
<u>Then the number of students passed in both subjects is:</u>
- x - (0.4x + 0.3x + 0.1x) =
- x - 0.8x =
- 0.2x
<u>Number of students passed in science is:</u>
- 0.3x + 0.2x = 200
- 0.5x = 200
- x = 200/0.5
- x = 400
Venn diagram looks like below.
<u>Consider 'Math' and 'Science' as two circles, 'Both' is the intersection of circles, 'Neither' is outside of the two circles.</u>
- Math Both Science Neither
- 40% 20% 30% 10%
