Answer:
(e) The women on the Maryland field hockey team are not a random sample of all female college field
hockey players. Similarly, the women on the Maryland basketball team are not a random sample of all female
college basketball players. However, for the purposes of this question, suppose that these two groups can be
regarded as random samples of all female college field hockey players and all female college basketball
players, respectively. If these were random samples, would you think that female college basketball players
are typically taller than female college field hockey players? Explain your decision using answers to the
previous questions and/or additional reasoning.
Answer: There are
ways of doing this
Hi!
To solve this problem we can think in term of binary numbers. Let's start with an example:
n=5, A = {1, 2 ,3}, B = {4,5}
We can think of A as 11100, number 1 meaning "this element is in A" and number 0 meaning "this element is not in A"
And we can think of B as 00011.
Thinking like this, the empty set is 00000, and [n] =11111 (this is the case A=empty set, B=[n])
This representation is a 5 digit binary number. There are
of these numbers. Each one of this is a possible selection of A and B. But there are repetitions: 11100 is the same selection as 00011. So we have to divide by two. The total number of ways of selecting A and B is the
.
This can be easily generalized to n bits.
Answer:
y = 8 · 10ˣ
Step-by-step explanation:
y = abˣ
When x = 0, y = 8.
8 = ab⁰
8 = a
When x = 3, y = 8000.
8000 = 8b³
1000 = b³
10 = b
The function is:
y = 8 · 10ˣ
I think this is right (x-2)(2x+y)
