Current Assets : $ 950.000 Current liabilities: $ 450.000 Current Cast of goods sold = $1.200.000 Quick ratio = 1,56 Q Calculate inventory turnover a) 4,8 timer b 35 times c) 3,0 timer.
d) 4,5 tiner

Answers

a) From the given information , upon calculation , the inventory turnover is 4.8 times.

To calculate the inventory turnover, we need to divide the cost of goods sold (COGS) by the average inventory. The quick ratio given is 1.56, which can help us find the average inventory.

Quick Ratio = (Current Assets - Inventory) / Current Liabilities

Rearranging the formula, we can find the inventory:

Inventory = Current Assets - (Quick Ratio * Current Liabilities)

= $950,000 - (1.56 * $450,000)

= $950,000 - $702,000

= $248,000

Now, we can calculate the inventory turnover:

Inventory Turnover = COGS / Average Inventory

Given that COGS is $1,200,000 and the average inventory is $248,000:

Inventory Turnover = $1,200,000 / $248,000

≈ 4.8 times

The inventory turnover is approximately 4.8 times. This means that the company sells and replaces its inventory about 4.8 times during the given period. A higher inventory turnover generally indicates efficient inventory management, as it implies that the company is selling its goods quickly and minimizing the risk of inventory obsolescence or spoilage.

grear tire company has produced a new tire with an estimated mean lifetime mileage of 33,500 miles. management also believes that the standard deviation is 3,500 miles and that tire mileage is normally distributed. to promote the new tire, grear has offered to refund some money if the tire fails to reach 30,000 miles before the tire needs to be replaced. specifically, for tires with a lifetime below 30,000 miles, grear will refund a customer $1 per 100 miles short of 30,000. (a) for each tire sold, what is the average cost of the promotion (in $)? (use at least 1,000 trials. round your answer to two decimal places.) $ (b) what is the probability that grear will refund more than $25 for a tire? (use at least 1,000 trials. round your answer to three decimal places.)

Answers

a) The average cost of the promotion is $0.01 per tire.

b) The probability that Greer will refund more than $25 for a tire is 0.9

According to the Question:

Greer Tire Company has:

Lifetime mileage = 33500

Standard Deviation = 3500 miles

a)

Meal lifetime mileage : $33,500

Standard deviation of mileage $3,500

Observed miles 30,000 miles

100 miles failed $1.00

Hence :

The average cost of the promotion:

= (33,500 – 30,000) / 3500

= 3500 /3500

= 1

Therefore,

Cost of production

100 miles = $1.00

= 1 * 1 / 100

= $0.01 per tire

b)

 P (z < 25000 -33500/ 3500

= P (z < -8500/ 3500)

= z < -2.4

Hence:

= 1 - 0.1

= 0.9

Therefore, the Probability that gear will refund more than $25.00 per tire is: 0.9

suppose that the bac of students who drink five beers varies from student to student according to a normal distribution with mean 0.07 and standard deviation of 0.01. show your work. a. the middle 99.7% of students who drink five beers have bac between what two numbers? b. what is the range for the 16% of lowest bacs? c. what percent of students have a bac above 0.09?

Answers

a. The middle 99.7% of students between 0.04 and 0.10.
b. The range for the 16% of lowest BACs is 0.06 or below.

c. 2.28% of students have a BAC above 0.09.

a. How to find range?

To find the range, use the properties of the normal distribution and the given mean (0.07) and standard deviation (0.01).

99.7% of the data lies within 3 standard deviations from the mean in a normal distribution.Calculate the lower bound: mean - 3 * standard deviation = 0.07 - 3 * 0.01 = 0.07 - 0.03 = 0.04Calculate the upper bound: mean + 3 * standard deviation = 0.07 + 3 * 0.01 = 0.07 + 0.03 = 0.10

The middle 99.7% of students between 0.04 and 0.10.

b. How to find range for 16% bacs?

To find the range use the z-score corresponding to the 16th percentile (z ≈ -1).

Calculate the BAC value corresponding to the z-score: BAC = mean + z * standard deviation = 0.07 + (-1) * 0.01 = 0.07 - 0.01 = 0.06

The range for the 16% of lowest BACs is 0.06 or below.

c. How to find percentage?

To find the percentage, find the z-score for 0.09 first.

Calculate the z-score: z = (BAC - mean) / standard deviation = (0.09 - 0.07) / 0.01 = 2Look up the area under the curve to the left of the z-score in a z-table (which is about 0.9772).Calculate the percentage of students above 0.09: 100% - 97.72% = 2.28%

Approximately 2.28% of students have a BAC above 0.09.

By multiplying 5/3^4 by _________, we get 5^4

Answers

The missing Value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

The missing value that, when multiplied by 5/3^4, gives the result of 5^4, we can set up the equation:

(5/3^4) * x = 5^4

To solve for x, we can simplify both sides of the equation. First, let's simplify the right side:

5^4 = 5 * 5 * 5 * 5 = 625

Now, let's simplify the left side:

5/3^4 = 5/(3 * 3 * 3 * 3) = 5/81

Now we have:

(5/81) * x = 625

To solve for x, we can multiply both sides of the equation by the reciprocal of 5/81, which is 81/5:

(81/5) * (5/81) * x = (81/5) * 625

On the left side, the fraction (81/5) * (5/81) simplifies to 1, leaving us with:

1 * x = (81/5) * 625

Simplifying the right side:

(81/5) * 625 = 13125

Therefore, the missing value, x, that when multiplied by 5/3^4 gives the result of 5^4 is 13125.

Caleb got internet service at home from a company called "Inter-What??". The company charged him $28 to hook it up. Then joined Netflix. He pays $14. 99 a month to keep the internet connected and he also pays the same amount for Netflix. Write an equation

Answers

Caleb's yearly expense for his internet service and Netflix subscription is $695.76.

To write an equation for Caleb's yearly expenses, we need to first determine his total monthly expense and then multiply it by 12 to get the yearly expense.

Caleb's monthly expense can be calculated as the sum of the internet and Netflix costs, which is:

$14.99 + $14.99 = $29.98

To include the initial setup fee of $28, we can add it to the monthly expense to get

$29.98 + $28 = $57.98

This is Caleb's total monthly expense, and to find his yearly expense, we can multiply it by 12

$57.98 x 12 = $695.76

Therefore, the equation for Caleb's yearly expense is

Yearly expense = 12 x (monthly internet cost + monthly Netflix cost + initial setup fee)

Yearly expense = 12 x ($14.99 + $14.99 + $28)

Yearly expense = $695.76

Answers

To determine which differential equation(s) are linear, we need to examine the form of each equation. A linear differential equation is one that can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x), b(x), c(x), and g(x) are functions of x.

The differential equation 2xy" - 5xy' + y = sin(3x) is linear. It can be written in the form a(x)y" + b(x)y' + c(x)y = g(x), where a(x) = 2x, b(x) = -5x, c(x) = 1, and g(x) = sin(3x).
The differential equation (v)² + xy = In(x) is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (v)², where v represents the derivative of y with respect to x. This term does not have a linear coefficient.
The differential equation y' + sin(y) = e^(3x) is linear. It can be written in the form a(x)y' + b(x)y = g(x), where a(x) = 1, b(x) = sin(y), and g(x) = e^(3x).
The differential equation (x²+1)y" - 3y - 2x³y = -x - 9 is not linear. It does not follow the form a(x)y" + b(x)y' + c(x)y = g(x) because it contains a term with (x²+1)y", where the coefficient is a function of x.

Answer:

One pecan cheesecake = $9

One apple cheesecake = $20

Step-by-step explanation:

This is a system of equations problem, so we can set up these equations (Note: p = pecan cheesecake cost | a = apple cheesecake cost):

8p + 12a = 312

9p + 6a = 201

Now, we can solve the system of equations. Below is an example of using the elimination method to solve the system:

1.    8p + 12a = 312 --> -4p - 6a  = -156        

     9p + 6a = 201  -->  9p + 6a = 201

2.                                  5p         = 45

3.                                    p         = 9

4.  8(9) + 12a = 312

    72   + 12a = 312

              12a = 240

                 a = 20

1. We try to make one of the terms equal to the negative version of the other term to eliminate that term; here, I am eliminating "a". To do this, find a multiple of one of the equations where one of the terms is the negative version of the other term. In other words, divide/multiply the equation by a number so one of the terms in the equation is the negative version of the term in the other equation (I divided the first equation by -2 so 12a becomes -6a, the negative version of 6a in the second equation.

2. Next, add the two equations' corresponding terms

(-4p + 9p = 5p; -6a + 6a = 0; -156 + 201 = 45)

3. Simplify the equation (5p = 45; p = 45/5; p = 9)

4. Substitute the term you found back into one of the equations to find the other term.

how many different ways can the letters of the word math be rearranged to form a four-letter code word? 1) 26 2) 25 3) 24

Answers

The answer is 3) 24.

An arithmetic progression or arithmetic sequence (AP) is a sequence of numbers such that the difference from any succeeding term to its preceding term remains constant throughout the sequence. The constant difference is called common difference of that arithmetic progression. For instance, the sequence 5, 7, 9, 11, 13, 15, . . . is an arithmetic progression with a common difference of 2.

To find the number of different ways to rearrange the letters in the word "math" to form a four-letter code word, we need to use the permutation formula, which is n! / (n-r)!, where n is the total number of items and r is the number of items being selected. In this case, n is 4 (the number of letters in the word "math") and r is also 4 (since we are forming a four-letter code word).

So the number of different ways to rearrange the letters in "math" is 4! / (4-4)! = 4! / 0! = 24. Therefore, the answer is 3) 24.

What are trigonometric ratios?

Trigonometric ratios are the ratios of the length of sides of a triangle. These ratios in trigonometry relate the ratio of sides of a right triangle to the their angles.

A right-angled triangle has 3 sides, hypotenuse, opposite and adjacent. The following should be noted:

Sin = Opposite / Hypothenuse

Tan = Opposite / Adjacent

Cos = Adjacent / Hypothenuse

When tan u = 15/8

Opposite = 15

Adjacent = 8

Hypothenuse will be:

= ✓(15² + 8²)

= ✓(225 + 64)

= ✓289

= 17

Therefore sin u = 15/17

When cos v = -5/13, it should be noted that sin v will be -12/13.

Therefore, sin(u + v) will be:

= 15/17 + (-12/13)

= 15/17 - 12/13

= 195/221 - 204/221
