Suppose the following data set represents the starting salaries for the population of teachers from nine states: $31,184
$43,839
$35,358
$31,606
$33,549
$39,196
$35,541
$34,972
$39,674
Part A: Calculate the mean of the data set. (3 points)
Part B: Calculate the five-number summary. (3 points)
Part C: Calculate the standard deviation of this data set. (4 points) (10 points)

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

the answer is option a you would get more money.it would be $250.

step-by-step explanation:

for option b 200/2=100=50% 100/2=50=25% 50/5=10=5% it would be $220
