Answer:
9000
Step-by-step explanation:
67.50 x 2 x 12 = 1620 (deduction for the whole yr)
1620 / 18 x 100 = 9000
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.
Answer:
Step-by-step explanation:
Note that the quadratic formula has that "plus or minus" due to our taking the square root of some quantity. No square root is involved in the two formulas you've posed.
I have two suggestions here:
1) Write " (x plus or minus y)^2 = x^ plus or minus 2 times xy + y^2 " Note that a + on the left side corresponds to a + on the right side, and same with - .
2) Memorize these two formulas, which in most algebra textbooks you'll find in the section "special products and factoring."
