-20 to -14 is 6
-14 to -8 is 6
-8 to -2 is 6
aritmetic sequence
an=a1+d(n-1)
a1=first term
d=common difference
n=which term
first term is -20
common difference is 6
we want 50th term
a50=-20+6(50-1)
a50=-20+6(49)
a50=-20+294
a50=274
the 50th term is 274

If you have a graphing calculator, go to 2nd vars, normalcdf(.
Put 150 for the lower bound and 99999999 for the upper bound. You want to know the probability of all the values over 150. Put 131.8 for the mean and 29.12 for the standard deviation. Click paste.
Your answer will be .266
Absolute value- the amount a number is away from zero. With this information, we can conclude,
|-12| = 12
|-15| = 15
