Answer:
Step-by-step explanation:
let the number of bracelet be b
Let the number of necklace be n
If Ashley charges $6 for a bracelet , the total amount charged for b bracelets will be 6b
If she charge $12 for a necklace, the total amount for n necklace will be 12n
If she earned $168 in total, then:
6b + 12n = 168
Divide through by 6
b + 2n = 28
Hence the equation for this situation is b + 2n = 28
Next is to solve for b:
Make b the subject of the formula:
b + 2n = 28
subtract 2n from both sides
b + 2n - 2n = 28 - 2n
b = 28 -2n
Hence the function for b will be b = 28-2n
Using the <u>Central Limit Theorem</u>, the statement is false, as for the averages of the data values for a sample group, the standard error is , hence, the formula is:
While for a single value, it is:
In a normal distribution with mean and standard deviation , the z-score of a measure X is given by:
- It measures how many standard deviations the measure is from the mean.
- After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.
- By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation .
Hence, the formulas are different, and for an average of the data values for a sample group it is:

Answer:
Step-by-step explanation:
x=150/10
=15
x=60
then y=60*1/15
=4
Answer:
if the basketball player makes the shot, then the team will advance to the playoffs (option d)
Explanation:
statement a is incorrect because the reverse of a statement is not always true. for example, all girls are humans but not all humans are girls. as such, we do not know that if the basketball player does not make the shot, the team will not win the game.
statement b is also incorrect, and uses a similar line of reasoning as statement a.
statement c is incorrect as well, and also uses the same reasoning as statements a and b.
statement d is correct. the reasoning used here is that if [x], then [y]. if [y], then [z]. thus, if [x], then [z].
i hope this helps! :D
