90 degrees
the diagonals intersect at right angles
41) you have a 40 day period
two visits with +75 centimeter growth each
3 visits with +6 each
in total 2*75+3*6=150+18=168
divide this by 40 days to get the average: 168/40=4.2 centimeters per day or 1.65 inches/day
42)
7x total
3x20
2x15
1x13
1x16
if you order these into a list:
13,15,15,16,20,20,20
the median is the middle value, in this case 16$
the mode is the most common value: 20$ which exists 3 times
