Standard deviation is the square root of the variance.
To find the variance from the standard deviation, raise it to the 2nd power:
Standard deviation = 4
Variance = 4^2 = 4x4 = 16.
Should be %50 because half of all numbers are even and half are odd (don’t quote me on that though)
The answer is 5 for your question
The answer is D. Linear equation
Answer:
Thus, option “c” 10% is correct.
Step-by-step explanation:
The percentage of students that like dubstep = 30%
The percentage of students that like trance music = 25%
The percentage of student that wants only house music = 20%
The percentage of students that like bot dubstep and trance = 15%
Now we have to find the percentage of students that like trance music but nor dubstep.
The percentage of students that like the trance music but nor dubstep = 100% - 30% – 25 % - 20% - 15%
The percentage of students that like trance music but nor dubstep = 10%
Thus, option “c” 10% is correct.
