In the freshman class, 62% of the students take math, 49% take science, and 38% take both science and math. what percentage take
antoniya [11.8K]

we are given

62% of the students take math

so,

n(M)=62

49% take science

n(S)=49

38% take both science and math

n(M∩S)=38

now, we can use union formula

n(M∪S)=n(M)+n(S) -n(M∩S)

now, we can plug values

and we get

n(M∪S)=62+49 -38

n(M∪S)=73

so,

the percentage takes at least one science or math course is 73%..........Answer

Please help, I’m not sure what the answer is.
Karo-lina-s [1.5K]

Answer:

The answer is 'C'

Step-by-step explanation:

Congruent simply means "the same." When a line divides two parralel lines transversals are created. This means that there are angles on both lines that are similar. To fully understand which angles would be the same, I reccommend researching "transversals" for more information, or asking your teacher about it as it is hard to explain without a proper diagram.
