Which of these triangle pairs can be mapped to each other using a single reflection? Triangles F E G and F G L are congruent. Triangle F E G is reflected across line F G to form triangle F G L. Triangles F E G and G L M are congruent. Triangle E F G is rotated about point G to form triangle G L M. Triangles F E G and L M N are congruent. Triangle F E G is shifted down and to the right to form triangle L M N. Triangles L M N and E F G are congruent. Triangle F E G is reflected across a line to form triangle L M N. Triangle L M N is also slightly higher and to the right of triangle E F G.

step-by-step explanation:

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

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.
