Consumer complaints are frequently reported to the Better Business Bureau. Industries with the most complaints to the Better Business Bureau are often banks, cable and satellite television companies, collection agencies, cellular phone providers, and new car dealerships.
a. Show the frequency and percent frequency of complaints by industry.
Industry Frequency % Frequency
Bank
Cable
Car
Cell
Collection
Total
b. Which industry had the highest number of complaints?
c. Comment on the percentage frequency distribution for complaints.
Answers
Answer:
(a)
\(\begin{array}{ccc}{Industry} & {Frequency} & {\%Frequency} & {Bank} & {26} & {13\%} & {Cable} & {44} & {22\%} & {Car} & {42} & {21\%}& {Cell} & {60} & {30\%} & {Collection} & {28} & {14\%} & {Total} & {200} & {100\%} \ \end{array}\)
(b): Cell industry
(c) See Explanation
Step-by-step explanation:
Given (Missing from the question)
\(Bank = 26\)
\(Cable = 44\)
\(Car = 42\)
\(Cell = 60\)
\(Collection = 28\)
\(Total = 200\)
Solving (a) Show the frequency and percent frequency.
The percentage frequency is calculated by:
\(\%Freq = \frac{Freq}{Total} * 100\%\)
So. we have:
\(\%Freq = \frac{26}{200} * 100\% = 13\%\) -- Bank
\(\%Freq = \frac{44}{200} * 100\% = 22\%\) --- Cable
\(\%Freq = \frac{42}{200} * 100\% = 21\%\) --- Car
\(\%Freq = \frac{60}{200} * 100\% = 30\%\) --- Cell
\(\%Freq = \frac{28}{200} * 100\% = 14\%\) --- Collection
The table becomes:
\(\begin{array}{ccc}{Industry} & {Frequency} & {\%Frequency} & {Bank} & {26} & {13\%} & {Cable} & {44} & {22\%} & {Car} & {42} & {21\%}& {Cell} & {60} & {30\%} & {Collection} & {28} & {14\%} & {Total} & {200} & {100\%} \ \end{array}\)
Solving (b): The industry with the highest complaints
From the above table, the highest frequency is 60 and this represents the number of complaints of Cell industry.
Hence, the cell industry has the highest number of complaints
Solving (c): Comment
The percentage frequency table shows that the industry with the highest number of complaints is the cell industry (at 30%) and the industry with the least is the banking industry (at 13%)

The polynomial's zeros must be located using a method of your choice, and the linear expressions that produce those zeros must then be combined in order to describe the polynomial as a product of linear factors.
What is a linear factor of a polynomial?The term "triple zero" or "zero with multiplicity 3" is used to describe this. The power p governs the behaviour close to the x-intercept if a polynomial has a factor of the type (xh)p. A zero of multiplicity p is defined as x=h. The x-axis will be touched at zeros with even multiplicities on a polynomial function's graph.
A real number is multiplied by an imaginary unit, I whose feature i2 = 1 defines it as an imaginary number. Bi is an imaginary number, while b2 is its square. For instance, the square of the fictitious integer 5i is 25. Zero is regarded as both real and fictitious by definition.
You must first determine the polynomial's zeros using the method of your choice, and then combine the linear equations that result in those zeros. If you factor, you will arrive at the third degree polynomial, which must then be sorted through.

Now Substitute these points to get a and b value
(0,37000) , (1,20350)
\(37000 = a \times {e}^{b \times 0} \)
\(37000 = a \times 1\)
Hence a=37000
Now Substitute t=1
\(20350 = 37000 \times {e}^{b \times 1} \)
\( \frac{20350}{37000} = {e}^{b} \)
\(0.55 = {e}^{b} \)
\(b = log_{e}(0.55) = - 0.5978\)
b≈(-0.6)
\(y = 37000 {e}^{ - 0.6t} \)

Find X,so that 7x+1,5x+7,and 2x-1 form an arithmetic sequence and write the first three terms.
Answers
The first three terms of the arithmetic sequence are -97, -63, and -29.
The value of x = -14.
How to Find the Terms in an Arithmetic Sequence?To find the value of x and the first three terms of the arithmetic sequence, we can equate the differences between consecutive terms:
The common difference (d) is the same between all consecutive terms.
So, we have:
(5x + 7) - (7x + 1) = (2x - 1) - (5x + 7)
Simplifying the equation:
5x + 7 - 7x - 1 = 2x - 1 - 5x - 7
-2x + 6 = -3x - 8
Now, let's solve for X:
-2x + 3x = -8 - 6
x = -14
Substituting the value of X back into the expressions, we can find the first three terms:
First term: 7x + 1 = 7(-14) + 1 = -97
Second term: 5x + 7 = 5(-14) + 7 = -63
Third term: 2x - 1 = 2(-14) - 1 = -29

Answer: f(x) has an axis of symmetry at x = 4 and h(x) has an axis of symmetry at x = -2
Step-by-step explanation:
You can easily find the axis of symmetry by investigating around which line the functions are symmetrical about
for instance, in h(x), the graph is symmetrical on either side of x = -2, meaning that the line x = -2 cuts the parabola in 'half'
in f(x), this is a little harder to think about, but if you know how the graph will be shifted on the x-axis you can figure it out! In this case (x-4)^2 means that the graph will be shifted on the x-axis 4 units to the right (or from the origin to +4 on the X axis)
as such the line x = 4 will cut the function f(x) in 'half'
Using the LIFO method and the information in this image, what is the Cost of Units on Hand and Cost of Goods Sold during this period?
Answers
Answer:
On hand: $3,120Sold: $14,480Step-by-step explanation:
You want the LIFO cost of units on hand, and the cost of goods sold if there are 60 units on hand that cost $52 and the total cost of all units was $17,600.
LIFOLIFO means "last in, first out". That is the oldest units remain in inventory to be the last ones sold. Here, the oldest units are from the first purchase, and are worth $52 each. There are 60 of them on hand, for a value of ...
units on hand = 60 × $52 = $3,120 . . . cost of units on hand
Goods sold
The remaining 240 units of the 300 purchased are goods that were sold. The total purchase was $17,600, so the cost of the goods that were sold is ...
$17,600 -3,120 = $14,480 . . . cost of goods sold
__
Additional comment
We could work backward through the purchases to find the cost of the 240 units sold. That would be the sum of the $6400 for the last 100, $6000 for the 100 previous to that, and $52 each for the 40 units sold from the first purchase.
Here, that arithmetic is made much easier by the fact that only 60 units from the first purchase remain in inventory. We can compute the value of remaining inventory and subtract that from the value of goods purchased to find the value of goods sold.
