The question is in the picture below

What is the arc length of the subtending arc for an angle of 72 degrees on a circle of radius 4? o a. 8a oc. 16 t d. 8

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone

The first several steps of evaluating (−2) (3 4 7 ) are shown, including the distributive property. (−2) (3 4 7 )  = (−2) ( 3 + 4 7 )  = (−2)(3) + (−2) ( 4 7 )  = (−6) + ( −8 7 ) what is (−2) ( 3 4 7 )
