The airline passenger association studied the relationship between the number of passengers on a particular flight and the cost of the flight. it seems logical that more passengers on the flight will result in more weight and more luggage, which in turn will result in higher fuel costs. for a sample of 8 flights, the correlation between the number of passengers and total fuel cost was 0.619. (1) state the decision rule for 0.01 significance level: h0: ? ? 0; h1: ? > 02) compute the value of the test statistic

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
