70.5
Set of Data (Prioritized):
31, 43, 47, 58, 63, 68, <u>69, 72,</u> 77, 84, 84, 84, 94, 97
To find the median:
(69 + 72) ÷ 2
= 70.5
Therefore, the median is equal to 70.5.
x×3/5=30
3x/5=30
3x=5×30
3x=150
x=150/3
x=50
c. a: 4
b: 12
c: 9
4x² +12x+9=0
(2x+3)(2x+3)= 0
(2x+3)²=0 {square root both sides}
2x+3=0
2x=-3
x= -3/2
