Answer:
It would be -81²x+81x-18= -9x+6
Step-by-step explanation:
When you work equation one you get 18. Then when you work equation two, you get -2/3=-0.666666667
Answer:
¾
Step-by-step explanation:
More than 3: 9
P(more than 3) = 9/12 = ¾
Answer:
Step-by-step explanation:
<u>Given polynomial:</u>
- x¹⁹ + x¹⁷ + x¹³ + x⁷ + x⁵ + x³
<u>Group as follows:</u>
- (x¹⁹ + x¹⁷) + (x¹³ + x¹¹) + (x⁷ + x⁵) + (x³ + x) - x =
- x¹⁷(x² + 1) + x¹¹(x² + 1) + x¹⁵(x² + 1) + x(x² + 1) - x
As we see all terms have (x² + 1) as factor apart from the last one.
It means the remainder is - x
Correct choice is C
The total number of arrangements for all of them to be women is:
C(7, 4) because the order does not matter; we'd still have the same arrangements.
Now, we can simplify this:




Now, the total number of arrangements, without restriction, is simply: C(12, 4) because we don't care who we pick.
