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
Answer:
x = 37.53
Step-by-step explanation:
Tan theta = opposite/adjacent
tan 47 = x /35
Multiply each side by 35
35 tan 47 = x/ 35 * 35
35 tan 47 = x
37.53290485=x
To two decimal places
x = 37.53
I think it’s y=2x-5 not sure tho
