Answer: 0.001
Step-by-step explanation:This is a combination problem, so we need to calculate the combination of 7 choose 5, and then multiply by the probability of each event:
Combination of 7 choose 5:
C(7,5) = 7! / (5! * 2!) = 7*6/2 = 21
This value means that we have 21 different possibilities of the 5 days we want being allocated in the 7 days
Now, the probability of each event is:
5 days playing the song: (0.15)^5
2 days not playing the song: (0.85)^2
So, the final probability is
P = C(7,5) * (0.15)^5 * (0.85)^2 = 0.001
2,8 meters than cuts it into 7 equal parts so each piece will be
2,8/7 = 0,4 meters

Answer:
Step-by-step explanation:
I encourage my Geometry students to be a bit more thorough than this proof table allows, but we can get it done anyway.

Answer:
The vertex is the point (4,3)
Step-by-step explanation:
we have
Convert to vertex form
Group terms that contain the same variable, and move the constant to the opposite side of the equation
Factor the leading coefficient
Complete the square. Remember to balance the equation by adding the same constants to each side.
Rewrite as perfect squares
----> equation in vertex form
The vertex is the point (4,3)
