"a class of 30 students took midterm science exams. 20 students passed the chemistry exam, 14 students passed physics, and 6 students passed both chemistry and physics. which venn diagram correctly represents this information? (see attachment)
a) venn diagram 1
b) venn diagram 2
c) venn diagram 3
d) venn diagram 4"

Option B). Venn diagram 2

Step-by-step explanation:

A class of 30 students took midterm science exams.

20 students passed chemistry exam, 14 passed physics and 6 students passed both physics and chemistry.

Since 6 students are common in both, so students who passed chemistry exam only will be = 20 - 6 = 14

And students who passed physics only = 14 - 6 = 8

So students who passed chemistry only are 14, students physics only are 8 and students who passed both the subjects are 6.

Moreover, students who couldn't pass any subject = 30 - (14 + 8 + 6) = 30 - 28 = 2

Option B) Venn diagram 2 is the correct option.

true

step-by-step explanation:

x is greater than 5

step-by-step explanation:

2x+7 is greater than 17

    -7                           -7

2x is greater than 10

divide by 2 each side

x is greater than 5
