Which sequence of transformations shows that triangle a is congruent to triangle b?

a: translate it 10 units to the left, and then rotate it 90 degrees clockwise about the origin

b: reflect it over the x-axis, and then reflect it over the y-axis

c: rotate it 180 degrees about the origin, and then translate it 10 units to the right

d: rotate it 180 degrees about the origin, and then translate it 10 units to the left

Step-by-step explanation:

I think it might be B

its 50 miles away from the starting point

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.
