Aeronautical researchers have developed three different processes to pack a parachute. They want to
compare the different processes in terms of time to
deploy and reliability. There are 1,200 objects that they
can drop with a parachute from a plane. Using a table
of random digits, the researchers will randomly place
the 1,200 items into three equally sized treatment
groups suitable for comparison. How many unique random numbers need to be
selected from the table of random digits?
0 3
O 400
O 800
O 1,200

step-by-step explanation:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.

step-by-step explanation:

given that megan owns a clothing boutique.

the profits of 2010, 11, are recorded and shown as follows:

years since     2010 0     1     2     3       4       5

profits made in 1000's   39       84     111     120   111     84

we find that profit gradually increases form 2010 to 2013 upto 120,   then starts decreasing.

the profits for 2012 and 2014 are the same while that of 2011 and 2015 are also the same.

this shows that there is symmetry about the line profit = 120000

hence answer is:

a.   since the profit made in 2012 is equal to the profit made in 2014, the profit is           symmetric about the line y = 120,000.
