<span>the correct answer is x^2</span>+5x+3=<span>0</span>
Solution :
Mean time for an automobile to run a 5000 mile check and service = 1.4 hours
Standard deviation = 0.7 hours
Maximum average service time = 1.6 hours for one automobile
The z - score for 1.6 hours = 
= 2.02
Now checking a normal curve table the percentage of z score over 2.02 is 0.0217
Therefore the overtime that will have to be worked on only 0.217 or 2.017% of all days.
The range is all real number greater than - 1
Answer:1. you can compute the slope, m
2. point (0,3) is the y-intercept; b=33
3. y = mx + b, so put the numerical values in for m & b. DON
