Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
Answer:7.15t
Step-by-step explanation:
You have to add 2.8t plus 5.7t together
Answer:
graph 2
Step-by-step explanation:
It is partially written in Slope-Intercept Form [<em>y</em><em> </em><em>=</em><em> </em><em>mx</em><em> </em><em>+</em><em> </em><em>b</em>]. That 2 tells you to move up two units.

Answer:
The polynomial function is 
Step-by-step explanation:
A polynomial function is completely determined by its roots, up to a constant factor. So, if we want that 
, 
and 
be roots of the polynomial P, we can write it as
Now, notice that the factor 
has real coefficients, while the other one don't. So, we need to ‘‘eliminate’’ the complex coefficients that will appear. This can be done adding other complex root to the polynomial: the conjugate of 
: 2-3i. Then,
Expanding the above expression we obtain the desired polynomial
Recall that P(x) must have three roots, and this implies that P has at least degree 3. As we had to add a new root in order to obtain real coefficients, the degree of P must be at least 4. With this reasoning we assure the minimal degree.
