Aclass 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?

Refer attachment for answer.

Step-by-step explanation:

Given :

Total students that took science exams (physics and chemistry) = 30

Total students that passed chemistry exams = 20

Total students that passed physics exams = 14

Total students that passed both physics and chemistry exams = 6

Let P denotes students who passed physics test , C denotes students who passed physics test and S denotes total students that took exam.

There are only two possibility that either student passed or fails in exam.

So, total students passed = total student passed in physics +  total student passed in chemistry - total student passed in both

= 14+20-6 = 28

Thus 2 (30-28) students got failed in both the exams.

Below Venn diagram (see the attachment ) represents the students who got passed in physics, chemistry or both and out of 30, 2 students did not passed so we put them outside the circle.

c. 65°

step-by-step explanation:

we are given a triangle with two known angles, 62° and 53°, while the third angle x is unknown and we are to find its value.

we know that the sum of angles in a triangle is equal to a total of 180 degrees. so we can write it as:

x + 62° + 53° = 180°

solving to find the value of x:

x = 180 - (62 + 53) = 65°

therefore, the value of x in this triangle is 65°.

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.
