Answer:
what set of numbers??
you haven't provided any set of numbers
the absolute value of -5/9, written |-5/9|, = 5/9.
Checking:-
5/ 9 = 0.55...
4/7 = 0.57
7/4 = 1.75
So C and D are greater than absolute value of -5/9.
Answer:
Now we can calculate the p value with the following probability taking in count the alternative hypothesis:
For this case since the p value is large enough we have enough evidence to FAIL to reject the null hypothesis and we can't conclude that we have significant differences between the two proportions analyzed.
Step-by-step explanation:
Information provided
represent the number of New Yorkers familiar with the brand
represent the number of Californians familiar with the brand
sample of New Yorkers
sample of Californians
represent the proportion New Yorkers familiar with the brand
represent the proportion of Californians familiar with the brand
represent the pooled estimate of p
z would represent the statistic
represent the value
System of hypothesis
We want to verify if the two proportions of interest for this case are equal, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
Where
Repalcing the info given we got:
Now we can calculate the p value with the following probability taking in count the alternative hypothesis:
For this case since the p value is large enough we have enough evidence to FAIL to reject the null hypothesis and we can't conclude that we have significant differences between the two proportions analyzed.

Hello!</h2>
The answers are:
a) The name of function is f.
b) Independent variable : x , dependent variable : y/f(x)
c) The rule that assings exactly one output to the very input is called "function".
d) ![f(4)=\frac{3}{4+2}=\frac{3}{7}](https://tex.z-dn.net/?f=f%284%29%3D%5Cfrac%7B3%7D%7B4%2B2%7D%3D%5Cfrac%7B3%7D%7B7%7D)
<h2>Why?</h2>
Usually, the name of a function
is what is out of the parentheses, so the name of the function is "f".
The independent variable of a function is the variable we assign the different values, so, for this case, the independent variable is designated with the letter "x"
The dependent variable is the function itself, it's also called "y", it's called "dependent" variable because its values will always depend on the "independent variable"
A function is a rule that states that there is exactly one output (range value) to the very input (domain value). A function only exists when there is exactly one output value (range) for each input (domain), if there is more than one output for each input, the function does not exist.
Evaluating a function consists of assign values to the independent variable(x), hence:
![f(4)=\frac{3}{4+2}=\frac{3}{7}](https://tex.z-dn.net/?f=f%284%29%3D%5Cfrac%7B3%7D%7B4%2B2%7D%3D%5Cfrac%7B3%7D%7B7%7D)
Have a nice day!
The best thing to do is to find what 1% is, and you can do this by dividing 150 by 100.
150/100= 1.5
As you're looking for 6.5%, you've got to multiply 1.5 by 6.5
1.5*6.5= 9.75
You've then got to add 9.75 and 150 together
150+9.75= $159.75
Therefore, after the sales tax, the cost of the necklace is $159.75
Hope this helps :)
