Answer: The answer is 12.
Step-by-step explanation: Given that a point 'x' is lying at 
on the number line. Another point 'y' is also lying at the same distance from 0 but has a numerator of 8. We are to find the denominator of 'y'.
Since 'x' is lying at on the number line so its distance from 0 will be
Let the denominator of 'y' be p, then its distance from 0 will be
According to the given information, we must have
Thus, the denominator will be 12.
Answer: 5...

Answer:
Option 2
Step-by-step explanation:
A 68% prediction interval for the output of 120 workers will be an interval which is of the length +/- 1* standard error of regression. Thus 68% PI is 131958 +/- 14994.93 i.e. option 2
