The manufacturer of hardness testing equipment uses steel-ball indenters to penetrate metal that is being tested. however, the manufacturer thinks it would be better to use a diamond indenter so that all types of metal can be tested. because of differences between the two types of indenters, it is suspected that the two methods will produce different hardness readings. the metal specimens to be tested are large enough so that two indentions can be made. therefore, the manufacturer uses both indenters on each specimen and compares the hardness readings. construct a 95% confidence interval to judge whether the two indenters result in different measurements.

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.
