Everyone thought that Martha Mathy was trying to start a new fashion trend when she started wearing socks that did not match. her "look" started to catch on, and pretty soon all the kids at her school were wearing mixed-up socks, too. Rita Writer, a reporter for the school paper, interviewed Martha about the new sock trend. " Wat gave you the idea to wear mismatched socks?" Rita Asked.
"Its simple mathematics," Martha replied. "you see, I have 18 socks at home but no two are the same. with just these 18 socks, I can create over 100 unique pairs of mismatched socks." Rita found this hard to believe, so she checked it out. Was Martha correct?
Answer:
There are 153 combinations
Combinations - any two from eighteen is given by the formula 18C2 or 18! / (2!*16!)
= 18 * 17 / 2 = 153
OK that is the maths - now the explanation
The first sock can be any of 18
The second sock can be any of 17 (one already been selected and they must be mismatched)
Therefore there are 18*17 = 306 permutations she could make
However the question asks for "combinations" not "permutations"
A green sock on the right foot and a yellow sock on the left foot is deemed to be a different "permutation" to a yellow sock on the right foot and a green sock on the left foot. HOWEVER, they are regarded as the same "combination" in both cases you have one green and one yellow sock.
Therefore for combinations we must divide the 306 permutations calculated above by 2 = 153
FYI Walton has incorrectly given you the value of 18!. That would only apply if Martha Mathy had 18 feet!
I am not sure how to solve this could anyone help???

which shows 2÷3 written as a fraction? (options) a. 2/3 b. 3 1/2 c. 3/2 d. 2 1/3
Answer:
A. 2/3
Step-by-step explanation:
Fraction is another way to divide , So in some math problems they want you to either flip the fraction or divide the numbers .
Option A is correct, the expression 2÷3 written as a fraction is 2/3.
What is Fraction?A fraction represents a part of a whole.
We have to write 2÷3 as a fraction.
Two divided by three.
We have to split the number two by three parts.
We know that any division expression can be written as a fraction, the numerator is a part and denominator is a whole.
Two is the numerator and three is the denominator.
The numerator represents the part and three represents the whole.
This we can write in fraction as 2/3.
Two by three is the fraction form of two divided by three.
Where as [tex]3\frac{1}{2}[/tex], is not a fraction, it is a mixed number.
3/2, is not equivalent to 2 ÷ 3, it represents the fraction one and a half and [tex]2\frac{1}{3}[/tex] is not equivalent to 2 ÷ 3, it represents the mixed number two and one-third.
Hence, Option A is correct, the expression 2÷3 written as a fraction is 2/3.

(Statistics) A local gym collects data on the number of memberships it sold in each month last year compared to the number sold in each month this year. For example, the January sales from last year are compared to the January sales from this year. Which of the following best describes the first step needed to simulate this data?
(Answer choices shown in photo. Will report fake/spam answers. Thanks for the help).
Answer:
Determine the proportion of months where memberships sold decreases,
increases and remained the same.
Step-by-step explanation:
I just took the test and got it correct.
The first step needed to simulate this data is:
Assign each month a digit from 1 to 24 to account for the 24 total months being compared.
Option B is the correct answer.
What is simulating data?Simulating data means creating artificial data that mimics the characteristics of real data.
This artificial data is generated by using a model or a set of rules that describe how the data might be generated under certain conditions.
We have,
The first step needed to simulate this data is to assign each month a digit from 1 to 24 to account for the 24 total months being compared.
This will allow for an easy comparison of the sales data from last year and this year.
Once each month has been assigned a digit, the data can be organized and analyzed to determine the proportion of months where memberships sold decreased, increased, and remained the same, as well as the mean monthly sales from last year and this year.
Finally, random digits can be assigned to each sales figure from last year and this year to create a simulated data set that can be used for further analysis and modeling.
Thus,
The first step needed to simulate this data is:
Assign each month a digit from 1 to 24 to account for the 24 total months being compared.
