Answer:
x³ - 5x² + 9x - 5
Step-by-step explanation:
If one root is 2 + i, other has to be 2 - i.
So at least 3 roots, minimum degree is 3
(x - 2 - i)(x - 2 + i)(x - 1)
[(x - 2)² - (i)²](x - 1)
(x² - 4x + 4 + 1)(x - 1)
(x² - 4x + 5)(x - 1)
x³ - 4x² + 5x - x² + 4x - 5
x³ - 5x² + 9x - 5
Answer:
-274
Step-by-step explanation:
425 - 699...is the same as 699 - 425...but after using this type of a method...remember to put a negative on your answer
:699 - 425 = 274
but the equation is 425 - 699...so your answer would be ( -274)
Answer:
0.0636
Step-by-step explanation:
The probability the first die has twelve sides is 4/11.
The probability the second die has twelve sides is 3/10.
The probability the third die does not have twelve sides is 7/9.
The probability the fourth die does not have twelve sides is 6/8.
The probability of all four events is:
4/11 × 3/10 × 7/9 × 6/8 = 0.0636
