A triangle has vertices at A(-6, -3), B(1,5), and C(4, 4). The triangle is
dilated according to the transformation
below. The center of dilation is the origin.
(x, y) = (2x, 2y)
What are the vertices of the image of the
triangle?
A A'(-12, -6), B'(2, 10), C'(8, -8)
B A'(-3,-1.5), B'(0.5, 5), C'(2,-2)
C A'(-12, 6), B'(2, 10), C'(8,8)
D A'(-12, -3), B'(2,5), C'(8,-4)

The investigating team suspected that there were differences in the cost of repairing cars in workshop i and workshop ii. the investigating team suspected that the costs raised by workshop i were greater than workshop ii. for that they tested the repair of 15 cars in each workshop to see the cost of repairs.the decision of the right hypothesis to prove the suspicion above is a. h0 : μ1- μ2­ = 0; ha : μ1- μ2­ ≠ 0 b. h0 : μ1- μ2 ≥ 0; ha : μ1- μ2 < 0 c. h0 : μd ≥ 0; ha : μd < 0 with μd = μ2- μ1 d. h0 : μd = 0; ha : μd ≠ 0 with μd = μ2- μ1 e. h0 : μ1- μ2 = 0; ha : μ1- μ2 ≥ 0
