when coin is flipped 5 times probability is 1/2
so coin heads comes out to be 2.5
This is a binomial distribution with a probability of success = 0.5 (fair coin).
n=10
so
mean = E[x] = np =10*0.5 =5
Answer:
D. No, the elements of the set of y are not all ordered pairs.
Step-by-step explanation:
Answer A. looks plausible: There are a few ordered pairs in this list, but that is not good enough.
All elements of the set should be ordered pairs and that is not the case. So answer D is correct.

Answer:
24
Step-by-step explanation:
Hello!
We can substitute 5 in for x in the equation and simplify.
<h3>Evaluate</h3>
- 4(x - 2)(x - 3) + 7(x - 2)(x - 5) - 6(x - 3)(x - 5)
- 4(5 - 2)(5 - 3) + 7(5 - 2)(5 - 5) - 6(5 - 3)(5 - 5)
- 4(3)(2) + 7(3)(0) - 6(2)(0)
- 4(3)(2) + 0 - 0
- 4(6) = 24
The evaluated value is 24.
