2 answers:
Answer: Length of MC is 16 milimeters
Step-by-step explanation:
Since we have given that
There is an equilateral triangle which has a perimeter of 96 milimeters.
As we know the formula for "Perimeter of equilateral triangle "
Since a perpendicular bisector is drawn from angle A to side BC at point M.
As we know that perpendicular bisector divide the line segment into two equal parts .
So, Length of MC will be
Hence, Length of MC is 16 milimeters.

Answer:
The probability that a student is an undergraduate student, given that the student received a plus grade is 0.92
Step-by-step explanation:
The conditional probability of an event <em>B</em> given that another event <em>A</em> has already occurred is:
Denote the events as follows:
<em>X</em> = a students is a graduate
<em>Y </em>= a students is a under-graduate
+ = a student received one or more plus grades
- = a student received one or more minus grades
Consider the tree diagram below.
According to the tree diagram, the probability that a student is an undergraduate student, given that the student received a plus grade is:
P (+ | Y) = 0.92
Thus, the probability that a student is an undergraduate student, given that the student received a plus grade is 0.92.
