Probability of the student taking neither math nor science is 35 / 150 or 0.23
<u>Explanation:</u>
<u />
Given:
Total students = 150
Number of students taking maths = 95
Number of students taking science = 75
Maths + Science = 55
Probability of student taking neither math nor science = ?
Number of students taking only science = 95 - 55
= 40
Number of students taking only maths = 75 - 55
= 20
Number of students taking neither maths nor science = 150 - 40 - 20 - 55
= 35
Probability of the student taking neither math nor science is 35 / 150 or 0.23
so.. to get every angle, simply plug in 10 for "x" for each.
make them both fractions with the same bottom number
3-7/8 = 31/8
2-1/4 = 9/4 ( need to multiply by 2 to make it match ) so it becomes 18/8
now subtract 2 top numbers 31-18 = 13 so now you have 13/8
8/8=1 so 13-8 = 5 so the answer will be 1 and 5/8
Answer:49
Step-by-step explanation: 9+4=13 4x2=8 8+1=9
9 is the units digit
4 is the tens digit
