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)? (x, y) - (x + 1, y + 1). (x, y) - (y, x):
(x, y) - (x + 1, y + 1), (x, y) + (-x, y),
O (X, Y) - (x, -y). (x, y) - (x + 2 y + 2)
O(x, y) + (-x, y). (x, y) - (x + 2 y + 2)

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
