X = 1 , y = - 2
Hope this helped
Looks like all real numbers except 1. It touch's all the y except 1 aka range
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
There are a total of 35 in the two clubs and 10 not in either. That makes 45 students, however there are only 32 in the class which means 45-32 = 13 students in BOTH clubs. So if we want to find how many are in only one club we can say 32 = 13 + 10 + x
x = 9 students in only one club
45 7 14 absolute value true the distance from 0 and -5 -3 -2 0 and 9
