They are equivalent. combine like terms on the first one and 9x-4x+25 can be simplified to 5x+25.
Answer:
A: 12/7
Step-by-step explanation:
Answer:
<h2>2/5</h2>
Step-by-step explanation:
The question is not correctly outlined, here is the correct question
<em>"Suppose that a certain college class contains 35 students. of these, 17 are juniors, 20 are mathematics majors, and 12 are neither. a student is selected at random from the class. (a) what is the probability that the student is both a junior and a mathematics majors?"</em>
Given data
Total students in class= 35 students
Suppose M is the set of juniors and N is the set of mathematics majors. There are 35 students in all, but 12 of them don't belong to either set, so
|M ∪ N|= 35-12= 23
|M∩N|= |M|+N- |MUN|= 17+20-23
=37-23=14
So the probability that a random student is both a junior and social science major is
=P(M∩N)= 14/35
=2/5
Answer:
140 degree
Step-by-step explanation:
Since the sum total of a polygon is 540 degree, simply subtracts from each degree of the other angles.
540 degree - 110 degree - 85 degree - 125 degree - 80 degree = 140 degree
Faucet one fills up
of the bathtub in one minute and faucet two fills up
of the bathtub in one minute. If both are one then they will fill up
So, 1/6 of the bathtub in one minute.
