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
So x is the number
x time 97.3%=36
percent measn parts out of 100 so
97.3%=97.3/100=9.73/10=0.973/1=0.973
x times 0.973=36
divide both sides by 0.973
x=36.9989...
answer is aprox 36.9
Multiply 1/4 (4r -12) = r-2
r-3 = r-2
Subtract r from each side
-3= -2 this equation has no solution
24$-100%
X $ - 120%
X=120•24:100=2880:100=28,8
Answer: Total bill is 28,8 $
Hi!
As per graph and question,
a) The most challenging is:-
<u>Examination B</u>
<em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em> </em><em>Reason</em> - There are few high scores and many low scores.
b) The least challenging is:-
<u>E</u><u>x</u><u>a</u><u>m</u><u>i</u><u>n</u><u>a</u><u>t</u><u>i</u><u>o</u><u>n</u><u> </u><u>C</u>
<em>Reason</em>- There are many high scores, few low scores and the lowest mark is not zero.
