Answer:

9.90 units (3 s.f.)

Step-by-step explanation:

distance formula

=  \sqrt{(x1 - x2)^{2}  + (y1 - y2)^{2} }

Length of WX

=  \sqrt{(2 - ( - 5))^{2}  + (6 - ( - 1)^{2} }  \\  =  \sqrt{(2 + 5)^{2}  + (6 + 1)^{2} }  \\  =  \sqrt{7 ^{2}  + 7^{2} }  \\  =  \sqrt{98}  \\  = 9.90 \: units \: (3 \: s.f.)

The length of time required for the periodic maintenance of an automobile or another machine usually has a mound-shaped probabil
maks197457 [2]

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 = $\frac{1.6-1.4}{0.7 / \sqrt{50}}$

                                           = 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.
