Gway to campus he wants to choose the path that has the lowest expected waiting time at stop lights. he collects the following data for three different options: path a path b path c number p(wait) time p(wait) time p(wait) time 1 0.25 3 0.05 5 0.45 4 2 0.10 2 0.35 4 0.20 1 3 0.525 2 0.35 1 0.75 2 (a) (5 points) calculate the expected number of minutes he will have to wait for each path

The correct answer is 7

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )

The discount is 8.70 . you dont tell us the percent of tax added so there is no way to find out, unless i'm not seeing anything. without tax its 37.70
