Nathan and Jordan design surveys to determine the average amount of time bicyclists in a race spend training each
week. Nathan surveys every fifth bicyclist crossing the finish line after a race. Jordan surveys the first five bicyclists to
finish the race. Which best explains which sample is likely to be the most valid?
Nathan's because his sample was more random
O Jordan's because his sample was more random
Nathan's because his sample contained elements of the population
Jordan's because his sample contained elements of the population
Answer: Nathan's because his sample was more random
Step-by-step explanation:
Nathan's survey could be described as a Systematic random sampling technique whereby every 5th observation taken as a sample from the population. With these technique we have a more random observation than with

32 25 18 11 4
These are the first 5 terms of sequence
Find(a)6th term
(b)nth term
(c)which term is equal to -332
Answers
A 3
B t = -7n +39
C 51.571
It is declining!
32 to 25 decreases by 7
25 to 18 decreases by 7
18 to 11 decreses by 7
The sequence is linear!
39 is the 0th term and our numbers are decreasing by 7 each term.
t = -7n +39 is our equation
a) -7(6) + 39
-49 + 39
3
b) to find nth term replace the term with n in this equation:
t = -7n +39
c) -332 = -7n +39
Subtract 39 from both sides!
-361 = -7n
Divide both sides by -7!
n = 51.571
The 6th term will be equal to -3, the nth term of the sequence will be equal to -7n + 39 and the term will be the 53rd term.
What is the arithmetic sequence?Two definitions are given for an arithmetic sequence. A "series where the variances in between every two succeeding terms are the same" is what it is.
Each term in an algebraic expression is created by multiplying its previous term by a specified integer (either positive, negative, or zero).
As per the given information in the question,
The sequence is given as:
32, 25, 18, 11, 4
(a)
a = 32
d = 25 - 32 = -7
n = 6
Then,
a₆ = a + (n - 1)d
a₆ = 32 + (6 - 1)(-7)
= 32 - 35
= -3
(b)
Find the nth term.
[tex]a_n[/tex] = a + (n - 1)d
= 32 + (n - 1)(-7)
= 32 -7n + 7
[tex]a_n[/tex] = -7n + 39
(c)
-332 = 32 + (n - 1)(-7)
-332 - 32 -7 = -7n
n = -371/-7
n = 53rd term.

Marie has a container of oatmeal. She uses 1/4 cup of the oatmeal for breakfast and 3/8 cup for a cookie recipe. What is the total change in the amount of milk she has? Why are 1/4 and 3/8 represented with negative numbers on the number line in the example
Answer:
-5/8
1/4 and 3/8 are represented as negative because it depicts a decline or reduction in the initial amount
Step-by-step explanation:
Given that :
Breakfast = 1/4 cup of Oatmeal
Cookie recipe = 3/8 cups
Change in total amount had :
total amount used = (breakfast + cookie recipe)
= 1/4 + 3/8
= (2 + 3) / 8
= 5 / 8
Hence, change in amount had = - 5/8
1/4 and 3/8 are represented as negative because it depicts a decline or reduction in the initial amount

You look at real estate ads for houses in Naples, Florida. There are many houses ranging from $200,000 to $500,000 in price. The few houses on the water, however, have prices up to $15 million. The distribution of house prices will be:_____. a. skewed to the left.b. roughly symmetric.c. skewed to the right.
Answer:
d. skewed to the right with possible outliers
Step-by-step explanation:
The distribution of house prices will be skewed to the right with possible outliers. This is because the regular median prices are still fairly far apart from each other with roughly $300,000 in difference between them. Also since there are some extreme house prices also included that greatly surpass the normal range these would be considered outliers in the data set.

i did this in my head, but the difference between -8 and 7 is 15. the difference between 2 and 7 is 5. it's rise over run so (15,5). that simplified is (3,1)/3. that is the slope. now you need a graph to see the y-int. the y-int is around 4.5.
