The stem and leaf plot shown displays the weights, in pounds of the dogs in an animal shelter. What is the median weight for the dogs in the animal shelter? A) 38 pounds

B) 44 pounds

C) 48 pounds

D) 49 pounds

B) 44 pounds

Step-by-step explanation:

the middle number is the midian

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

source:

a - base

b - exponent

so,
