Answer:
Step-by-step explanation:
Since, The total number of student = 300
Out of which,
The number of students who are only in Maths = 120
And, The number of students who are only in Science = 50
While, the students who are not from any subject = 100
Hence, the number of student who are from both maths and science = Total student - Maths student (only) - science student (only) - None
= 300 - 120 - 50 - 100
= 30
That is, there are 30 students who are both from science and maths,
Thus, the probability of selecting one student who is both from maths and science = 30/300 = 1/10
Assuming each statement is claiming the first set is a subset of N, the second statement is false. 0 is not part of the natural numbers.
<h3>
Answer: C) 4/5</h3>
=========================================================
Explanation:
Recall that y = mx+b is the slope intercept form
m = slope
b = y intercept
In this case, y = (4/5)x-3 has m = 4/5 as the slope and b = -3 as the y intercept.
In short, the slope is simply the number to the left of the x variable.
The answer to this question will be 45 because you minus 15 on both sides and get 45 for 60 minus 15 and then will minus 2x on both sides and the Equation will now be x=45 and you plug it in to check
You just need to isolate it, hope this explains it
