TAKE AWAY X SUBTRACT BY 4
Answer:
the range is most affected by an outlier. it makes it seem like there is a bigger variety of numbers being shown.there will be one all by itself on a dot plot
This is a simple example:-
x + 9
------------------------------
x - 1 ) x^2 + 8x - 9
x^2 - x subtract
------------
9x - 9
9x - 9
----------
..........
First divide x into x^2 to give x which goes above
Then multiply x - 1 by x to give x^2 - x
Subtract this fro x^2 + 8x gives 9x
Bring down the - 9 then divide x into 9x
and finally multiply x - 1 by 9 to give 9x - 9
Finally subtract and you sre done. There is no remainder as x - 1 is a factor of x^2 + 8x - 9.
The polynomial must be in descending powers of x . If one is missing you insert it with a coefficient of zero before you start the division.
for example if you have x^3 - 3x + 12 you write it as
x^2 + 0x^2 - 3x + 12
Answer:
x = + 3, -3
Step-by-step explanation:
both are 3 away from 0
Answer:
0.0713 = 7.13% probability that the result is positive.
Step-by-step explanation:
Probability of a positive test:
91% of 1/650(has the disease).
7% of 1 - 1/650 = 649/650(does not have the disease). So
0.0713 = 7.13% probability that the result is positive.
