In a math class with 20 students, a test was given the same day that an assignment was due. There were 12 students who passed the test and 13 students who completed
the assignment. There were 10 students who passed the test and also completed the
assignment. What is the probability that a student chosen randomly from the class
passed the test and completed the homework?
=1/2

step-by-step explanation: 6870

1857 times .63 equals 1169.91 subtract that from 1857 you get 687.09

answer: 1 and 3

step-by-step explanation:

1/4 because there is 4 grades.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
