I NEED THIS PLEASE A triangle has vertices at B(−3, 0), C(2, −1), D(−1, 2). Which transformation would produce an image with vertices B″(1, −2), C″(0, 3), D″(3, 0)?
A.(x, y) → (x + 1, y + 1), (x, y) → (y, x)
B.(x, y) → (x + 1, y + 1), (x, y) → (−x, y),
C.(x, y) → (x, −y), (x, y) → (x + 2, y + 2)
D.(x, y) → (−x, y), (x, y) → (x + 2, y + 2)

3.17 scores on stats final. below are final exam scores of 20 introductory statistics students. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 57, 66, 69, 71, 72, 73, 74, 77, 78, 78, 79, 79, 81, 81, 82, 83, 83, 88, 89, 94 (a) the mean score is 77.7 points. with a standard deviation of 8.44 points. use this information to determine if the scores approximately follow the 68-95-99.7% rule. (b) do these data appear to follow a normal distribution? explain your reasoning using the graphs provided below.
