Wholemark is an internet order business that sells one popular New Year greeting card once a year. The cost of the paper on the
erma4kov [3.2K]

Answer:

The optimal production quantity is 9,322 cards.

Step-by-step explanation:

The information provided is:

Cost of the paper = $0.05 per card

Cost of printing = $0.15 per card

Selling price = $2.15 per card

Number of region (n) = 4

Mean demand = 2000

Standard deviation = 500

Compute the total cost per card as follows:

Total cost per card = Cost of the paper + Cost of printing

                                = $0.05 + $0.15

                                = $0.20

Compute the total demand as follows:

Total demand = Mean × n

                       = 2000 × 4

                       = 8000

Compute the standard deviation of total demand as follows:

SD_{\text{total demand}}=\sqrt{500^{2}\times 4}=1000

Compute the profit earned per card as follows:

Profit = Selling Price - Total Cost Price

         = $2.15 - $0.20

         = $1.95

The loss incurred per card is:

Loss = Total Cost Price = $0.20

Compute the optimal probability as follows:

\text{Optimal probability}=\frac{\text{Profit}}{\text{Profit+Loss}}

                               =\frac{1.95}{1.95+0.20}\\\\=\frac{1.95}{2.15}\\\\=0.9069767\\\\\approx 0.907

Use Excel's NORMSINV{0.907} function to find the Z-score.

<em>z</em> = 1.322

Compute the optimal production quantity for the card as follows:

\text{Optimal Production Quantity}=\text{Total Demand}+(z\times SD_{\text{total demand}}) \\

                                               =8000+(1.322\times 1000)\\=8000+1322\\=9322

Thus, the optimal production quantity is 9,322 cards.

Your friend finds that the correlation between shoe size and iq is r = 1. 99. what should you say about these findings?
Gennadij [26K]

An error was made, correlation values can't be greater than 1.00.

The strength of the linear association between two variables is quantified by the correlation coefficient. The correlation coefficient always takes a value between -1 and 1. The 1 represents the perfect positive correlation and -1 represents the perfect negative correlation whereas the 0 represents the no correlation between two variables.

So, if the value of the correlation coefficient between shoe size and IQ is r = +1.99 then,

Analysts in some fields do not consider a correlation significant until the value is at least 0.8. However, a correlation coefficient with an absolute value of 0.9 or greater indicates a very strong relationship. 2.

Select the three equations that are correct.
nika2105 [10]

Answer:

6 × 9 = 54

42 ÷ 7 = 6

56 ÷ 7 = 8

Step-by-step explanation:

Given:

6 × 9 = 54

8 × 4 = 34

42 ÷ 7 = 6

64 ÷ 9 = 7

56 ÷ 7 = 8

Now it need to verify,

6 × 9 = 54 this is correct

42 ÷ 7 = 6 This is also correct

56 ÷ 7 = 8 This is correct

Jodie wanted to match Mandy's obstacle course record of 73.4 seconds. She had already spent seconds on wall climbing and 11.78 s
Artyom0805 [142]

The time left to match the record will be 61.62 seconds. The correct option is A.

<h3>What is an expression?</h3>

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that Jodie wanted to match Mandy's obstacle course record of 73.4 seconds. She had already spent seconds on wall climbing and 11.78 seconds on the ropes.

The time left to match the record will be calculated as below:-

Time left = 73.4 - 11.78 = 61.62

Therefore, the time left to match the record will be 61.62 seconds. The correct option is A.
