The difference in a variable measured over observations (time, customers, items, etc.) is known as the variance.
it is the measure of variability that utilizes all the data and it is calculated by
 taking the differences between each number and the mean,. Then these differences are squared in order to be positive. At the end the sum of the squares is divided by the number of values in the set.

Your business has purchased 500 pizza pans, 60 kg of sauce, 100 kg of cheese, 2.5 kg of basil, 2.5 kg of oregano, 5 kg of yeast,

adelina 88 [10]

Answer:

400 pizzas

Explanation:

The complete question would be:

You are going into the business of making pizzas. The following is the list of ingredients to make ONE pizza:

400 g flour 50 mL water

10 g yeast 120 g sauce

250 g cheese 5 g oregano

5 g basil

Your business has purchased 500 pizza pans, 60 kg of sauce, 100 kg of cheese, 2.5 kg of basil, 2.5 kg of oregano, 5 kg of yeast, and 200 kg of flour. You have as much water as you need. How many pizzas can you make?

You are going to have to make a couple of conversions to do this. Since everything you need is indicated in grams, we first need to convert everything you have in grams.

There are 1,000 g in 1 kg. So now we convert them all:

60 kg of sauce

$60kg \times \dfrac{1,000g}{1kg} = 60,000g$

100 kg of cheese

$100kg \times \dfrac{1,000g}{1kg} = 100,000g$

2.5 kg of basil

$2.5kg \times \dfrac{1,000g}{1kg} = 2,500g$

2.5 kg of oregano

$2.5kg \times \dfrac{1,000g}{1kg} = 2,500g$

5 kg of yeast

$5kg \times \dfrac{1,000g}{1kg} = 5,000g$

200 kg of flour

$200kg \times \dfrac{1,000g}{1kg} = 200,000g$

So now that we know what we have, we determine how many pizzas we can make with the amount of each ingredient. We get the ratio of each ingredient to one pizza to determine how many we can make:

Flour:

Available: 200,000g

Needed: 400g

$200,000g\ of\ flour\times\dfrac{1\ pizza}{400g\ of\ flour} = 500\ pizzas$

Yeast:

Available: 5,000g

Needed: 10g

$5,000g\ of\ yeast\times\dfrac{1\ pizza}{10g\ of\ yeast} = 500\ pizzas$

Cheese:

Available: 100,000g

Needed: 250g

$100,000g\ of\ cheese\times\dfrac{1\ pizza}{250g\ of\ cheese} = 400\ pizzas$

Basil:

Available: 2,500g

Needed: 5g

$2,500g\ of\ basil\times\dfrac{1\ pizza}{5g\ of\ yeast} = 500\ pizzas$

Sauce:

Available: 60,000g

Needed: 120g

$60,000g\ of\ sauce\times\dfrac{1\ pizza}{120g\ of\ sauce} = 500\ pizzas$

Oregano:

Available: 2,500g

Needed: 5g

$2,500g\ of\ oregano\times\dfrac{1\ pizza}{5g\ of\ oregano} = 500\ pizzas$

We do not need to consider water, because it will provide as many as we will need.

So here we see that all but one ingredient is able to yield 500 pizzas. Cheese is the only one that yields less than 500, specifically 400 only. This is your limiting ingredient and this ingredient determines how many pizzas you can make. Because when you run out of cheese, you can no longer make a pizza.

Constant cost industries:

adoni [48]

Answer:

The correct answer to the following question will be Option C.

Explanation:

Constant cost industries seem to be a sector wherein the proportion of units produced as well as manufacturing costs every unit maintains the very same irrespective including its amount of manufacturing or rise in population. Which doesn't use input data in the appropriate amount to influence the rates of that same components by a shift in industry revenue.
This doesn't even use inputs in such amounts that perhaps the costs of that same inputs will be influenced by a change in business production.

The other choices are not linked to an industry of this kind. Therefore the clarification above is correct.

You currently own shares in Buckeye Mutual Fund (BMF). Your broker calls and recommends buying shares in a small-capitalization

GarryVolchara [31]

Answer:

Option D is the correct option

Explanation:

To find the optimal fund to combine with risk free rate of return, we will use Coefficient of variation,

Coefficient of variation(CoV) = Standard Deviation/Expected Return

CoV of Buckeye = 14%/20% = 0.7

CoV of Wolverine = 11%/12% = 0.9167

So, higher the CoV higher the risk, we will take Buckeye to combine with Risk Free Return.

Hence, Option A

- Required target return of portfolio = 22%

Risk Free return = 8%

Buckeye Return = 20%

Let the weight of Buckeye be X ,& weight of risk free be (1-X)

Required return = (WRF)*(RRF) + (WB)*(RB)

22 = (1-X)(8) + (X)(20)

22 = 8-8X + 20X

14 = 12X

X = 1.17

SO, weight of Buckeye is 1.17 or 117%

while weight of Risk free is -0.17 (1-1.17) or -17%

Hence, ans is OPTION D
