At a fast-food restaurant, if the average time to serve a customer is 3.75 minutes for 10 samples of size 5, and the average range for the samples is 0.50 minutes, the upper and lower control limits for a 3-sigma x̄-chart are
a. UCL = 5.08, LCL = 4.94
b. UCL = 5.75, LCL = 1.75
c. UCL - 3.91, LCL - 3.60
d. UCL - 4.04, LCL - 3.46

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.

um is there supposed to be a picture?
