Percent of children under five considered to be underweight. Percent of Underweight Children Number of Countries 16–21.45 23 21.45–26.9 4 26.9–32.35 9 32.35–37.8 7 37.8–43.25 6 43.25–48.7 1 What is the best estimate for the mean percentage of underweight children? What is the standard deviation? ( consider this sample data ( not population data ) Consider that unusual values are typically more than 2 standard deviations ( ±2sx ) from the mean. Therefore, which interval(s) could be considered unusual? Explain.

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

he has now walked a total of what?

if i know what this is maybe i can
