According to given ratios, the inventory turnover for 20Y7 is 4.83 and the inventory turnover for 20Y6 is 5.30.
What is ratio?
A ratio is a mathematical comparison between two or more quantities. It expresses the relationship between the two quantities by dividing one quantity by the other.
Inventory turnover is a financial ratio that measures how many times a company sells and replaces its inventory over a period of time. It is calculated by dividing the cost of goods sold by the average inventory for the period.
a. To determine the inventory turnover for 20Y7 and 20Y6, we first need to calculate the average inventory for each year:
Average inventory = (Beginning inventory + Ending inventory) / 2
For 20Y7:
Average inventory = ($770,000 + $840,000) / 2 = $805,000
For 20Y6:
Average inventory = ($740,000 + $770,000) / 2 = $755,000
Next, we can calculate the inventory turnover for each year:
Inventory turnover 20Y7 = Cost of goods sold / Average inventory 20Y7
= $3,894,000 / $805,000
= 4.83
Inventory turnover 20Y6 = Cost of goods sold / Average inventory 20Y6
= $4,001,500 / $755,000
= 5.30
Therefore, the inventory turnover for 20Y7 is 4.83 and the inventory turnover for 20Y6 is 5.30.

Pete surveyed his friends as to the amount of their weekly allowance. the responses were $5, $0, $8, $10, $8, $10, $0, $0, and $1. Pete analyzed the results and stated that more than half of his friends earned $8 or more per week. Find his mistake and correct it. Statical queston
Answer:
Step-by-step explanation:
Bold = $8 or more per week, Underlined = less than 8 per week
$5 = 1 person
$0 = 3 people
$10 = 2 people
$1 = 1 person
$8 = 2 people
The total amount of people = 1+3+2+1+2 = 9
The total amount of people who earn less than $8/week = 1+3+1 = 5 people
The total amount of people who earn $8 or more/week = 2+2 = 4 people
Conclusion, 5/9 total people earned less than $8/week
4/9 people earn $8 or more/week
Mistake there were less than half people who earned $8 or more per week unlike Pete stated
Correction; more than half of Pete's friends earn less than 8 dollars per week
Write the expression in terms of sine and cosine, and simplify so that no quotients appear in the final expression. tan x(cot x - cos x)
Answer: Starting with the expression:
tan(x)(cot(x) - cos(x))
Recall that cot(x) is the reciprocal of tan(x), so we can substitute cot(x) = 1/tan(x):
tan(x)(1/tan(x) - cos(x))
Simplifying:
1 - cos(x)tan(x)
Next, we can use the identity cos(x) = 1/sec(x) to eliminate the cotangent term:
1 - (1/sec(x))tan(x)
Now, we can use the identity tan(x) = sin(x)/cos(x) and sec(x) = 1/cos(x) to express the expression in terms of sine and cosine:
1 - (1/cos(x))(sin(x)/cos(x))
Simplifying:
cos(x)/cos(x) - sin(x)/cos(x)
= (cos(x) - sin(x))/cos(x)
Therefore, the simplified expression in terms of sine and cosine is:
(cos(x) - sin(x))/cos(x)
Step-by-step explanation:
The function f is defined by f(x) = −x³ + 3x²
6x and the point (1,-4) is on
the graph of f. If f-¹ is the inverse function of f, what is the value of (ƒ-¹)' (-4)?
-
The inverse function of f, what is the value of (ƒ-¹)' (-4) -1/16 ∓ i/(8√3)
We know that the point (1,-4) is on the graph of f, so we can use this information to find the value of x for which f(x) = -4:
-4 = -x³ + 3x² + (6x)
-x³ + 3x² + 6x + 4 = 0
We can solve this equation using various methods, such as graphing, factoring, or using the cubic formula. One possible method is to use synthetic division to test factors of the constant term (4) and find one that gives a remainder of zero. By testing -1 as a factor, we get:
-1 | 1 -3 6 4
-1 4 -10
1 -4 10 -6
Therefore, the equation can be factored as:
-(x + 1)(x² - 4x + 6) = 0
Using the quadratic formula or completing the square, we can find the roots of the quadratic factor:
x = 2 ± √2i
Since the function f is not one-to-one, we must restrict its domain to make it invertible. One possible domain is x ≤ 2, so the inverse function f⁻¹(x) is:
f⁻¹(x) = 1 ± √(1 - 2x)/x
Note that there are two possible values for f⁻¹(-4), one for each branch of the inverse function. To find the value of (f⁻¹)'(-4), we need to take the derivative of the inverse function at x = -4:
(f⁻¹)'(x) = -1/x² ∓ √(1 - 2x)/2x³
(f⁻¹)'(-4) = -1/16 ∓ i/(8√3)
Therefore, the value of (f⁻¹)'(-4) is either -1/16 - i/(8√3) or -1/16 + i/(8√3), depending on which branch of the inverse function we choose.

The probability of selecting a vowel first and then not a vowel second is 2/6 x 5/5 = 10/30 = 1/3.
What is Probability?Probability is a branch of mathematics that deals with the likelihood of something happening. It is used to quantify the chance of a certain event occurring and can help to predict the outcome of a given situation. Probability is based on the concept of randomness, which is the idea that an event's outcome is determined by chance and cannot be controlled or predicted.
The word "replacement" contains 2 vowels (e,a) and 4 consonants (r,p,l,c). Therefore, the probability of selecting a vowel first is 2/6 (2 out of 6 cards are vowels). Since there are 5 cards left after the first selection, the probability of selecting a non-vowel second is 5/5 (5 out of 5 cards are non-vowels).
Therefore, the probability of selecting a vowel first and then not a vowel second is 2/6 x 5/5 = 10/30 = 1/3.

Chuck's Chops, an up-scale steak house, received an invoice for 800 pounds of baking potatoes with a cost of $.85 per pound. The terms were, n/30. Chuck was unable to pay the bill in full within the discount period but was able to remit a partial payment of $425.00 within the discount period. How much credit did Chuck receive for his payment?
Chuck received a credit of $369.15 for his partial payment.
What is simple interest?
The interest on a loan or principal sum can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more.
The total cost of the baking potatoes is calculated by multiplying the weight of potatoes by the cost per pound:
800 pounds x $0.85/pound = $680
Since the terms are n/30, Chuck has 30 days to pay the invoice in full to receive the discount. He made a partial payment of $425 within the discount period, which means he has a remaining balance of:
$680 - $425 = $255
To determine how much credit Chuck received for his partial payment, we need to calculate the discount he would have received if he had paid the full amount within the discount period. The discount is calculated by multiplying the total cost by the discount rate, which is calculated by dividing the discount period by the number of days in the year:
Discount rate = discount period / number of days in the year
Discount rate = 30 / 365
Discount rate = 0.0822
Discount = total cost x discount rate
Discount = $680 x 0.0822
Discount = $55.85
Since Chuck only paid $425 within the discount period, he is entitled to a credit for the remaining discount amount:
Credit = Discount - Partial payment
Credit = $55.85 - $425
Credit = -$369.15
Therefore, Chuck received a credit of $369.15 for his partial payment.

how to find area and perimeter of Rhombus
Answer:
To find the area and perimeter of a rhombus, you can follow these steps:
1. Find the length of one side of the rhombus.
2. Use the length of one side to find the length of the diagonals. The diagonals of a rhombus are perpendicular bisectors of each other, which means that they intersect at a 90-degree angle, and each diagonal cuts the rhombus into two congruent right triangles. The length of each diagonal can be found using the Pythagorean theorem: diagonal^2 = (side/2)^2 + (side/2)^2.
3. Once you have found the length of the diagonals, you can use them to calculate the area of the rhombus. The area of a rhombus is equal to half the product of the length of the diagonals: area = (diagonal1 x diagonal2) / 2.
4. To find the perimeter of the rhombus, you simply add up the lengths of all four sides: perimeter = 4 x side.
In summary, the steps to find the area and perimeter of a rhombus are:
1. Find the length of one side of the rhombus.
2. Use the length of one side to find the length of the diagonals.
3. Use the diagonals to calculate the area of the rhombus: area = (diagonal1 x diagonal2) / 2.
4. Add up the lengths of all four sides to find the perimeter: perimeter = 4 x side.
To find the area and perimeter of a rhombus, you can use the following formulas:
Area = (diagonal 1 × diagonal 2) / 2
Perimeter = 4 × side length

If you were to buy one of each bond today, you would have to spend b. ABC $1104.75 and XYZ $1100.50.
Calculate Price of Bonds Based on Yield and Coupon Payment?The following algorithm must be used to determine a bond's price:
[tex]Bond\ price=(\frac{coupon\ payment}{(1+yield)^{time}} )+(\frac{coupon\ payment}{(1+yield)^{time+1}} )+...+(\frac{coupon\ payment+face\ value}{(1+yield)^{Time+n}} )[/tex]
Where:
dividend Payment: The bond's yearly dividend payment (in dollars)
Yield: The bond's yield to expiration (as a decimal)
Time: the interval between the issuance of each coupon and the receipt of its monetary value. (in years)
Face worth: The bond's face worth (in dollars)
The price of each bond can be determined as follows using the data in the table:
a. For bond ABC:
Coupon Payment = $7.50 (7.5% of $1000 face value)
Yield = 3.04% (convert 3.04 to a decimal)
Time = 0.5 years (since the bond's maturity date is July 15 and today marks the midway point between those dates)
Face Value = $1000
[tex]Bond\ price=(\frac{7.5}{(1+0.0304)^{0.5}} )+(\frac{7.5}{(1+0.0304)^{1.5}} )+(\frac{1000}{(1+0.0304)^{2}} )[/tex]
= 7.356 + 7.235 + 925.984
= $940.575
Since we are purchasing one bond and the face value is $1,000, we split this amount by 10 to get the price for one bond:
Price for one bond ABC = $940.575 / 10 = $94.058
b. For bond XYZ:
Coupon Payment = $84 (8.4% of $1000 face value)
Yield = 1.7% (convert 1.7 to a decimal)
Time = 0.5 years
Face Value = $1000
[tex]Bond\ Price = (84 / (1 + 0.017)^{0.5}) + (84 / (1 + 0.017)^{1.5}) + (1000 / (1 + 0.017)^2)[/tex]
= 83.379 + 81.838 + 968.661
= $1133.878
Since the face value of a bond is $1,000 and we are only purchasing one, we split this amount by 10 to get the price for one bond:
Price for one bond XYZ = $1133.878 / 10 = $113.388
Therefore, the correct answer is:b. ABC: $1104.75 XYZ: $1100.50

1. The solutions of the equation 6/(x+1)= x/(x-1) are x = 2 and x = 3.
2. The solutions of the equation x+ 4/x= -5 are x = -1 and x = -4.
What are the solutions ?
1. 6/(x+1) = x/(x-1)
To solve this equation, we first need to get rid of the fractions by multiplying both sides of the equation by the least common multiple of the denominators, which is (x+1)(x-1):
6(x-1) = x(x+1)
Expanding the left side, we get:
6x - 6 = x² + x
Moving all the terms to one side, we get:
x² - 5x + 6 = 0
This is a quadratic equation that can be factored as:
(x - 2)(x - 3) = 0
So, the solutions are x = 2 and x = 3. However, we need to check if these solutions are valid, because we cannot divide by zero.
Checking x = 2:
6/(2+1) = 2/(2-1)
2 = 2, which is true
Checking x = 3:
6/(3+1) = 3/(3-1)
3/2 = 3/2, which is true
Therefore, the solutions are x = 2 and x = 3.
2. x + 4/x = -5
To solve this equation, we first need to get rid of the fraction by multiplying both sides of the equation by x:
x² + 4 = -5x
Moving all the terms to one side, we get:
x² + 5x + 4 = 0
This is a quadratic equation that can be factored as:
(x + 1)(x + 4) = 0
So, the solutions are x = -1 and x = -4. However, we need to check if these solutions are valid, because we cannot divide by zero.
Checking x = -1:
-1 + 4/(-1) = -5
-1 - 4 = -5, which is true
Checking x = -4:
-4 + 4/(-4) = -5
-4 - 1 = -5, which is true
Therefore, the solutions are x = -1 and x = -4.

A 14- ladder is leaning against a building. If the bottom of the ladder is sliding along the pavement directly away from the building at 3feet/second, how fast is the top of the ladder moving down when the foot of the ladder is 5 feet from the wall?
The company will start to turn a profit when x is greater than -22. In other words, the company will start to turn a profit when they sell more than 22 units of their product.
What is inequalities
In mathematics, an inequality is a mathematical statement that indicates that two expressions are not equal. It is a statement that compares two values, usually using one of the following symbols: "<" (less than), ">" (greater than), "≤" (less than or equal to), or "≥" (greater than or equal to).
To find the point at which the company starts to turn a profit, we need to find the value of x for which the revenue is greater than the cost of production.
The revenue function is R(x) = 7x, and the cost of production is C(x) = 13x + 132.
So, we need to solve the inequality:
R(x) > C(x)
7x > 13x + 132
Subtracting 13x from both sides, we get:
-6x > 132
Dividing both sides by -6 (and flipping the inequality because we're dividing by a negative number), we get:
x < -22
Therefore, the company will start to turn a profit when x is greater than -22. In other words, the company will start to turn a profit when they sell more than 22 units of their product.

Sheila is climbing on a ladder that is attached against the side of a jungle gym wall. She is 7 feet off the ground and is 3 feet from the base of the ladder, which is 18 feet from the wall. How high up the wall is the top of the ladder?
The top of the ladder is about 24.81 feet up the wall.
EquationsWe can use the Pythagorean theorem to solve the problem and assume the height up the wall that the top of the ladder reaches "x". Then, we have a right triangle with legs of 3 feet and x feet and a hypotenuse of 18 + 7 = 25 feet (the length of the ladder). So, we can write:
[tex]3^{2}[/tex] + [tex]x^{2}[/tex] = [tex]25^{2}[/tex]
9 + [tex]x^{2}[/tex] = 625
[tex]x^{2}[/tex] = 616
x = [tex]\sqrt{616}[/tex]
x ≈ 24.81 feet
What are the components of Pythagoras Theorem?According to Pythagoras's Theorem, the square of the length of a right-angled triangle's hypotenuse (the side that faces the right angle) is equal to the sum of the squares of the lengths of the other two sides (the adjacent and opposite sides) and this can be expressed mathematically as follows [tex]c^{2}[/tex]= [tex]a^{2}[/tex] + [tex]b^{2}[/tex] where c is the hypotenuse's length and a and b are the lengths of the other two sides.

The vertex οf the parabοla is at the pοint (-3/2, -21/4) and the range οf the functiοn wοuld be (-21/4, infinity).
What is the quadratic functiοn?A quadratic functiοn is a functiοn οf the fοrm where a, b, and c are cοnstants, and a is nοt equal tο 0. It is a type οf pοlynοmial functiοn that can be graphed as a parabοla, which is a symmetric curve that οpens either upwards οr dοwnwards.
Given the table οf pοints fοr the cοntinuοus quadratic functiοn h(x), we can find the vertex and range οf the functiοn. Since the functiοn is quadratic and cοntinuοus, it can be represented in the standard fοrm [tex]$f(x)=a(x-h)^{2}+k,$[/tex], where (h, k) is the vertex οf the parabοla.
Tο find the vertex, we can use the fact that the x-cοοrdinate οf the vertex is given by -b/2a, where a and b are the cοefficients οf the quadratic term and the linear term, respectively. In this case, a = 1 (since the functiοn is cοntinuοus and quadratic), and b can be fοund using any twο pοints οn the parabοla:
[tex]\rm b=(h(x_2)-h(x_1))/(x_2-x1)=(4-7)/(-2+1)=3$[/tex]
Therefοre, the x-cοοrdinate οf the vertex is x = -b/2a = -3/2. Tο find the y-cοοrdinate οf the vertex, we can evaluate the functiοn at this value οf x:
[tex]$\rm h(-3/2)=(1)(-3/2-h)^{2}+k$[/tex]
Tο sοlve fοr k, we can use οne οf the pοints οn the parabοla, say (-6, 12):
[tex]$12=(1)(-6-h)^{2}+k\,$[/tex]
Expanding and simplifying, we get:
[tex]$12=(h-6)^{2}+k$[/tex]
Substituting -3/2 fοr h, we get:
[tex]$\begin{array}{l}{{12=(-(3/2)-6)^{2}+k}}\\\\ {{12=81/4+k}}\\\\ {{k=-21/4}}\end{array}$[/tex]
Therefοre, the vertex οf the parabοla is at the pοint (-3/2, -21/4).
Tο find the range οf the functiοn, we can lοοk at the shape οf the parabοla. Since the cοefficient οf the quadratic term is pοsitive, the parabοla οpens upwards, and the vertex is the lοwest pοint οn the graph. Therefοre, the range οf the functiοn is all real numbers greater than οr equal tο the y-cοοrdinate οf the vertex, which is -21/4. In interval nοtatiοn, we can write the range as (-21/4, infinity).
Hence, the vertex οf the parabοla is at the pοint (-3/2, -21/4) and the range οf the functiοn wοuld be (-21/4, infinity).

If the variance of the data values in a population is 441, what is the standard deviation of the data values?
O A. 17
• B. 21
O C. 23
O D. 19
In the given situation if the variance of the data values in a population is 441, the standard deviation of the data values is (B) 21.
What is the standard deviation?The term "standard deviation" (or "σ") refers to a measurement of the data's dispersion from the mean.
A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
While a high standard deviation suggests that the values are dispersed throughout a wider range, a low standard deviation suggests that the values tend to be close to the established mean.
The variance's square root is the standard deviation of the data values:
S = √V = √441 = 21
Therefore, in the given situation if the variance of the data values in a population is 441, the standard deviation of the data values is (B) 21.
