Answer:
x = - 3 ± 3
Step-by-step explanation:
given the equation x² + 6x - 9 = 0
We can solve for x using the quadratic formula
x = ( - b ± 
) / 2a
with a = 1, b = 6 and c = - 9
x = ( - 6 ± 
) / 2
= ( - 6 ± 
) / 2
= ( - 6 ± 
) / 2
= ( - 6 ± 6 ) / 2
x = - 3 ± 3

Answer:
Ella should add 
lbs of water.
Total weight of syrup 
lbs
Step-by-step explanation:
Weight:
Weight of sugar = 0.5 lbs.
Weight of water added = x lbs
Total weight = 0.5 + x lbs
Percentage:
0.5 + x -- 100%
0.5 -- 1.5%
Write a proportion:
Cross multiply:
Ella should add lbs of water.
Total weight of syrup
The outlier (61) is at the low end of the data set, but doesn't affect the mean by a lot, so ...
The mean is centered among the other numbers in both sets of data.
_____
The mean without the outlier is 114. With the outlier, it is 107.4. The lower quartile is 108, so the mean does get moved outside the "box" of the box-and-whisker plot of the data set without the outlier.
