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
The slope of the line is 2
Step-by-step explanation:
Px^2+6x+1=x^2+x^2+Qx+1
P=2 and Q=6
Next, 3x^2-5-(x^2-6x+R/2)=2x^2+6x+1
2x^2-5-R/2+6x=x^2+6x+1
-5-R/2=6, R=-22
Answer:
D m = 
Step-by-step explanation:
factor the expressions in the denominator and the numerator to simplify the expression:
=> 
=> 
to make a fraction undefined, the numerator should be 0, thus, we substitute the values of m from the options into the denominator to make the denominator equals to 0:
=> 
= 
= 
in this case, the values of m from option D make the denominator of the fraction equals 0.
