Suppose the heights (in inches) of men (ages 20–29) years old in the United States are normally distributed with a mean of 69.3 inches and a standard deviation of 2.92 inches.

1. The percent of men who are between 63.46 inches and 75.14 inches tall.
2. The percent of men who are taller than 72.22 inches.
3. The percent of men who are between 60.54 inches and 78.06 inches tall.
4. The percent of men who are shorter than 60.54 inches.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

step-by-step explanation:

abc

the correct answers i think are b. and d.

give me brainliest if it is correct!
