Answer:
Hello :
4x² - 8x +3 = 0
4 ( x² - 2x +3/4 ) = 0
4 ( (x² -2x +1) -1 + 3/4) = 0
4 ((x-1)² - 1/4 ) =0
(x-1)² - 1/4 = 0
(x-1)² - ( 1/2 )²=0
( x - 1 -1/2 ) ( x - 1 +1/2 ) = 0
( x - 3/2) ( x - 1/2) = 0
x - 3/2 = 0 or x - 1/2 = 0
two solutions : 3/2 ; 1/2
Quantitative data is information that can be measured, while qualitative data is descriptive data which can not be measured.
All five measures (the mean, the median, the trimmed mean, the weighted mean and the mode) can be calculated for quantitative data only, because they all use values in order to be calculated.
The answer is 256 hope this helps :)
