(e) The women on the Maryland field hockey team are not a random sample of all female college field
tia_tia [17]

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.

Let n be a positive integer and define [n] to be the set of the first n positive integers. That is, [n] = {1, 2, 3, . . . , n}.
yaroslaw [1]

Answer: There are 2^{n-1} 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 2^5 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 2^{5-1} = 2^4.

This can be easily generalized to n bits.

Write an exponential function in the form y=ab^xy=ab
Tcecarenko [31]

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
