3) median and mode!
Explanation:
Median- 3,4,5,(5),7,9,19
Mode- 5 is repeated.
55 is your answer
each number added together sums up to $330
there are 6 numbers
if you divide 330 by 6 you will get 55
If you mean 165x = 31 , X = <span>0.19871794871
if you mean 16*5x = 31 , X = .3875
if you mean 16+5x=31 , X = 3
If you mean 16 -5x=31 , X = -3
Hope one of these is correct.</span>
Writing the word problem as an equation you get:
x - 18 ≥ -12
Now to solve for x:
Add 18 to both sides of the inequality:
x ≥ -12 + 18
Simplify:
x ≥ 6
