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:
69 and 30
Step-by-step explanation:
Using the formula with d = 96
=
+ 5 =
+ 5 = 64 + 5 = 69 in
=
- 2 = 32 - 2 = 30 in
Divide 432.5 by 3 which gives you 144.16 ounces
Answer:
Step-by-step explanation:
1
- IQR's
- Ride A: 30 - 20 = 10
- Ride B: 30 - 10 = 20
- False, as 10 < 20
2
- Medians
- Ride A: 25
- Ride B: 20
- False, as 25 > 20
3
- Ranges
- Ride A: 45 - 5 = 40
- Ride B: 35 - 0 = 35
- TRUE, as 40 > 35
4
- Minimum
- Ride A: 5
- Ride B: 0
- TRUE, as 0 < 5
Given:
p = 20% = 0.2, sample proportion
n = 5000, sample size.
Confidence level = 95%
The confidence interval is
(p - 1.96k, p + 1.96k)
where

Therefore the 95% confidence interval is
(0.1943, 0.2057) = (19.4%, 20.6%)
Answer: The 95% confidence interval is (19.4%, 20.6%)
