U mean 4x-4^2=3^2 ? if u mean that the ans would be 6,25
This is a binomial experiment and you'll use the binomial probability distribution because:
- 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).
- 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%
- 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.
The answer is C
The original spot for A is (2,-4)
Multiply it my the decimal form 3/4
.75*2=3/2
.75*-4=-3
Hope this helps!
Answer:
1/4 - 1/8 = 2/8 - 1/8 = 1/8
