So it’s option 1
Step-by-step explanation:
Answer:
$0.31
Step-by-step explanation:
3/4 = $0.75
$0.75 - $0.44 = $0.31
Step-by-step explanation:
the median for the upper quartile is 21 or second quartile
Given the quadratic function, to get the roots we factorize:
3x²-4x-7=0
3x²+3x-7x-7=0
3x(x+1)-7(x+1)=0
(3x-7)(x+1)=0
thus the roots are
x=-1 or x=3/7
thus the sum of the roots will be:
-1+3/7
=-4/7
