Explain how counting number of girls in five children family can be treated as a binomial experiment. What assumptions are neces
Juliette [100K]

This is a binomial experiment and you'll use the binomial probability distribution because:

  1. There are two choices for each birth. Either you get a girl or you get a boy. So there are two outcomes to each trial. This is where the "bi" comes from in "binomial" (bi means 2).
  2. Each birth is independent of any other birth. The probability of getting a girl is the same for each trial. In this case, the probability is p = 1/2 = 0.5 = 50%
  3. There are fixed number of trials. In this case, there are 5 births so n = 5 is the number of trials.

Since all of those conditions above are met, this means we have a binomial experiment.

Some textbooks may split up item #2 into two parts, but I chose to place them together since they are similar ideas.

Which expression finds the measure of an angle that is coterminal with a 126° angle?
N76 [4]
The expression that gives an angle that is coterminal with 126 is 126 + 720n. Two angles are said to be coterminal if when they are drawn in a standard position, their terminal sides are on the same location. The expression will give an angle which when it is drawn the terminal sides are on the same location with the 126 angle.

Is this the correct surface area? Explain how you know​
yarga [219]

Answer:

  No. The actual total surface area is double that: 108 in².

Step-by-step explanation:

The area Charlotte has computed is the area of the faces you can see. There are three other faces you cannot see that are the same size. So, the total area is double the amount Charlotte has computed.

  A = 2(LW +H(L+W)) = 2(6·4+3(6+4)) = 2(24+30) = 2(54) = 108 . . . . sq in
