intext:"A quality control engineer wishes to perform an estimate of the average amount a machine is filling a can. He knows the distribution is normal and wants to be accurate within .05 oz and knows the standard deviation is 1.1 oz. If he will be performing a 99% confidence interval, what size sample does he need?"

Step-by-step explanation:

what are the options? ?

step-by-step explanation:

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
