Find the minimum cost of producing 50,000 units of a product, where x is the number of units of labor (at $36 per unit) and y is
erastovalidia [21]

Answer:

Step-by-step explanation:

Given problem: C(x,y) = 36x + 48y

constraint: 100x^0.6y^0.4

Using langrange Multiplier,

36 = 0.6(100)x^-0.4y^0.4λ         i

48 = 0.4(100)x^0.6y^-0.6λ         ii

dividing the equations we have:

x = 2y

substituting into the constraint

p(x,y) = 100 *(2y)^0.6 y^0.4 = 100*2^0.6 *y

5000  = 151.572y

y = 329.876 labor units

x = 659.752 capital units

Minimum cost = 36(659.752) +48(329.876) = $39585.12

Farhan orders one plate of seafood fried rice at a restaurant which offers at 25% discount. the Marked price of the seafood frie
ANTONII [103]

Answer:

The total amount of money he has to pay for the dish is $8.3861.

Step-by-step explanation:

Here, the marked price of the seafood fried rice  = $9.50

Now, discount on the marked price  = 25%

Calculating 25% of $9.50 = \frac{25}{100}  \times 9.50 = 2.375

So, the discount offered = $2.375

Now, the Selling Price of dish = Marked Price - Discount

                                                    =  $9.50 - $2.375   = $7.125

Now, here the service charge applied here  = 10%

Calculating 10% of $7.125 = \frac{10}{100}  \times 7.125 = 0.7125

So, the service charge applied  = $0.7125

So, the new Selling Price of dish = Selling Price + Service Charge

                                                    =  $7.125 + $0.7125   = $7.8375

Again, here the GST applied here  = 7%

Calculating 7% of $7.8375 = \frac{7}{100}  \times 7.8375 = 0.5486

So, the GST applied  = $0.5486

So, the new Selling Price of dish = Selling Price + GST

                                                    =  $7.8375 + $0.5486   = $8.3861

Hence, the total amount of money he has to pay for the dish is $8.3861.

A company surveyed 2500 men where 1225 of the men identified themselves as the primary grocery shopper in their household. ​a) E
professor190 [17]

Answer:

a) The 98% confidence interval for the population proportion of males who identify themselves as the primary grocery shopper is (0.457, 0.503).

b) The null hypothesis that the proportion is equal or less than 44% will be rejected at this level of significance.

c) The level of significance is 2%.

This is the expected probability that the sample proportion fall outside the acceptance region due to pure chance, if the null hypothesis is true.

Step-by-step explanation:

a) The conditions are:

- randomization: it is assumed to be a random sample.

- independence: the sample responses are independent of each other.

- 10% condition: we don't know the size of the population, but the sample is assumed to be less than 10% of the population.

- sample size: the sample size is bigger than 30, so it is satisfied.

We have to calculate a 98% confidence interval for the proportion.

The sample proportion is p=0.48.

p=X/n=1225/2550=0.48

The standard error of the proportion is:

\sigma_p=\sqrt{\dfrac{p(1-p)}{n}}=\sqrt{\dfrac{0.48*0.52}{2550}}\\\\\\ \sigma_p=\sqrt{0.0001}=0.0099

The critical z-value for a 98% confidence interval is z=2.326.

The margin of error (MOE) can be calculated as:

MOE=z\cdot \sigma_p=2.326 \cdot 0.0099=0.023

Then, the lower and upper bounds of the confidence interval are:

LL=p-z \cdot \sigma_p = 0.48-0.023=0.457\\\\UL=p+z \cdot \sigma_p = 0.48+0.023=0.503

The 98% confidence interval for the population proportion of males who identify themselves as the primary grocery shopper is (0.457, 0.503).

b) Our confidence interval tells us that there is 98% confidence that the true proportion o males who identify themselves as the primary grocery shopper is within 0.457 and 0.503.

The propotion 0.44 is outside of this interval, so if the claim is that the proportion is higher than 44%, the null hypothesis will state that the true proprotion is equal or less than 0.44.

With the information we have, at this level of significance (2%), the null hypothesis will be rejected.

c) The level of significance that corresponds to the 98% confidence interval is α=2%.

This is the expected probability that the sample proportion fall outside the acceptance region (which matches with the confidence interval) due to pure chance, if the null hypothesis is true.
