Answer:
y = 12665 (100⁻¹) + b
Step-by-step explanation:
To model this relationship, you're to write the equation of a line; in the form
y = mx + b
Now let y represent the full coupon value,
mx represent the amount spent by Hellen and her sister
and b, the change that's left on the coupon.
So, the summary of Hellen's transaction is:
$85.2 became $(85.2 - 12.78) which is = $72.42
The summary of her sister's transaction is:
$63.8 became $(63.8 - 9.57) which is = $54.23
So y - (72.42 + 54.23) = b
y - 126.65 = b
y = 126.65 + b
Separating m from x in mx, you have
y = 12665 x 1/100 + b
y = 12665 (100⁻¹) + b
Where m = 12,665 and x = 100⁻¹

True or false:a. If the proportion of defectives in the sample is less than 12%, it is reasonable to conclude that the new process is better.b. If the proportion of defectives in the sample is only slightly less than 12%, the difference could well be due entirely to sampling variation, and it is not reasonable to conclude that the new process is better.c. If the proportion of defectives in the sample is a lot less than 12%, it is very unlikely that the difference is due entirely to sampling variation, so it is reasonable to conclude that the new process is better.
Answer:
false
Step-by-step explanation:
In a population, the percentage or fraction which is not conforming to (defeating) is defined as a ratio of the population's figures of non-conforming goods to the sum of goods in the inhabitants, and the further discussion can be defined as follows:
In option A, it is wrong because the proportion of both the sample is simply an approximation. The real percentage could be more than 12%. Furthermore, the conclusion also that the new procedure is better cannot be reasonably concluded.In options (b and c) both are correct because it is based on the explanation of whether, if the fraction of defective differences is bigger, we can only determine that its new procedure is better or not as a minor difference may occur from the variance of samples.Learn more:

Find the series:0,2,6,12,20and.......?
Answer:
The series is represented by sum [tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex]. The remaining element of the series is 30.
Step-by-step explanation:
This exercise consist in deriving the function which contains every element of the given series. The sum that contains all elements of the series { 0, 2, 6, 12, 20,...} is represented by the following formula:
[tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex] (1)
Where [tex]n[/tex] is the cardinal associated with the element of the series.
Lastly, we proceed to evaluate the sum for the first five elements:
n = 0
[tex]f(0) = 0[/tex]
n = 1
[tex]f(1) = 0 +2[/tex]
[tex]f(1) = 2[/tex]
n = 2
[tex]f(2) = 0 + 2 + 4[/tex]
[tex]f(2) = 6[/tex]
n = 3
[tex]f(3) = 0 + 2 + 4 + 6[/tex]
[tex]f(3) = 12[/tex]
n = 4
[tex]f(4) = 0+2+4+6+8[/tex]
[tex]f(4) = 20[/tex]
The series is represented by sum [tex]f(n) = 2 \cdot \Sigma\limits_{i=0}^{n} n[/tex], [tex]n \in\mathbb{N }[/tex].
Lastly, the missing element is found by evaluating the function at [tex]n = 5[/tex], that is:
n = 5
[tex]f(5) = 0 + 2 + 4 + 6 + 8 + 10[/tex]
[tex]f(5) = 30[/tex]
The remaining element of the series is 30.

Today, everything at a store is on sale. The store offers a 25% discount.
If the regular price of an item is x dollars, what is the discount price in dollars?
Answer:
dived the price by two and dived that answer by two
Step-by-step explanation:
lets say the price is 245 you dived it by two
245/2= 122.5 that's 50 percent of the price so you dived it bye two
122.5/2=61.25
so that's 25 percent of the price

I WILL GIVE BRAINLIEST Which of the following tables of x– and y–values represents a function? Select all that apply.
Answer:
A and C
Step-by-step explanation:
For a table of x and y variables to be a function, each x-value must not have two different y-values assigned or related to it. However, different x-values can have the same y-value.
Therefore, the table in option A and option C are functions because every of their x-value has exactly one y-value that corresponds it.
