15 POINTS! Plot ΔABC on graph paper with points A(3,3), B(1,1), and C(6,1). Reflect ΔABC by multiplying the y-coordinates of the vertices by −1. Then use the function (x, y)→(x−6,y−3) to translate the resulting triangle. Name the coordinates of the vertices of the result.

(a) A'(-3,3), B'(-1,1), C'(-1,6)

(b) A'(-3,-6), B'(-5,-4), C'(0,-4)

(c) A'(-6,-3), B'(-4,-5), C'(-4,0)

(d)A'(3,-3), B'(1,-1), C'(6,-1)

The weekly amount spent by a company for travel has an approximately normal distribution with mean = $550 and standard deviation = $40. a) what is the probability that the actual weekly expense will exceed $570 for more than 20 weeks during the next year? (note: one year = 52 weeks) b) what is the probability that actual weekly expenses exceed $580 for 10 or more, but 16 or fewer weeks during the next year?
