For each scenario, state what type of sampling method is used. A website asks people to rate how much they liked the website and how easy it was to use.
100 houses are randomly surveyed to determine how much hydro they are using.

To determine what fast food people are eating in a city, one neighbourhood is randomly selected, and then one street is randomly selected in that neighbourhood and everyone on that street was surveyed.

To determine what the school should spend their budget on, 8 grade 9s,10 grade 10s, 9 grade 11s and 7 grade 12s were surveyed , proportional to their populations in the schools ( 160 grade 9s, 200 grade 10s, 180 grade 11s, and 140 grade 12s)

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
