Answer:
You are looking at a computer printout of 100 test scores, which have been converted to standard units. The first 10 entries are - 3.1 2.4 0.18 0.56 0.32 0.74 0.99 0.0244 3.7. Does the printout look reasonable, or
Median-the middle number in a set of data
Mean-the average of a set of data
Mode-the number that occurs most often in a set of data
Outlier-a number that is much bigger or smaller than the other numbers in a data set
I’m so sorry if it’s wrong-
2x + 5 3x + 5 x + 1
--------------- - ----------------- - -------------------
x(x - 3) x (x+3)(x-3) (x +3)(x - 3)
(x + 3) (2x + 5) - (3x + 5) - x ( x + 1)
= ---------------------------------------------------------
x (x+3)(x-3)
2x^2 +6x +5x + 15 -3x - 5 -x^2 - x
= -----------------------------------------------
x (x+3)(x-3)
x^2 + 7x + 10
= --------------------
x (x+3)(x-3)
(x +5)(x+2)
= --------------------
x (x+3)(x-3)
or
(x +5)(x+2)
= --------------------
x^3 - 9
answer is A. first one
Well you want to do 7.8 divided by 2 which is 3.9. Then you add that to 7.8 to signify that is it 1 1/2 which is 11.7. You subtract that from 60 and you get 48.3 and that is your answer
