b. 15-19=-4

Explanation:

This problem can be solved with a very simple rule that is, Bodmas stands for "brackets, orders, division, multiplication, addition, subtraction". if integers contain brackets ((), {}, []) then first solve bracket then powers and roots etc., then division, multiplication, addition and subtraction from your left to right.

PEMDAS is very similar to BODMAS and used in the USA.

PEMDAS means Parentheses, Exponents (powers and roots), Multiplication and Division, Addition and Subtraction.

Suppose that three firms make up the entire wig manufacturing industry. One has a 60% market share, and the other two have a 20%

Answer:

Increase

c. An index of 10,000 corresponds to a monopoly firm with 100% market share

Explanation:

Here are the options to the last question

Why is the largest possible value of the Herfindahl index 10,000 ?

a. An index of 10,000 corresponds to 100 firms with a 1% market share each

b. An industry with an index higher than 10,000 is automatically regulated by the Justice Department

c. An index of 10,000 corresponds to a monopoly firm with 100% market share

HHI index = 60² + 20² + 20² = 4400

If one of the firms leaves the industry, the market share would be distributed between the two firms and this would cause the HHI index to increase as firm's concentration would increase

If only one firm operates in the industry, its market share would be 100% and its HHI index would be 100² = 10,000. For an industry to exist there has to be at least one firm operating in the industry,

Phillippe invested $1,000 ten years ago and expected to have $1,800 today. He has not added or withdrawn any money from this acc

weqwewe [10]

Answer:

d) He earned a lower interest rate than he expected

Explanation:

Data provided in the question

Invested amount ten years ago = $1,000

Expected amount = $1,800

Today amount = $1,680

Based on the above information,

Since the bond is based on the floating rate not the fixed rate that results in the value of the investment to $1,800

And, the today amount is $1,680 i.e. less than the expected amount so the internet rate should be less as compared with the expected rate

hence, correct option is d.

A manufacturer estimates that its product can be produced at a total cost of C(x) = 50,000 + 100x + x3 dollars. If the manufactu

timofeeve [1]

Answer:

The level of production x that will maximize the profit is: 22,966

Explanation:

C(x) = 50,000 + 100x + x³

R(x) = 3400x

P(x) = R(x) - C(x)

= 3400x - [50,000 + 100x + x³]

= 3400x - 50,000 - 100x - x³

= 3300x - 50,000 - x³ .................... (A)

P'(x) = 3300(1) - 0 - 3x²

= 3300 - 3x²

At a critical point, P'(x) = 0

∴ 0 = 3300 - 3x²

3x² = 3300

x² = 1100

x = ± $\sqrt{1100}$

P"(x) = -6x

P( $\sqrt{1100}$ ) = -6 ( $\sqrt{1100}$ ) < 0

by second derivative, 'P' max at x = $\sqrt{1100}$ = 33.17 (rounds)

since x = $\sqrt{1100}$ ,

recall that P(x) = 3300x - 50,000 - x³ from equation (A)

Therefore, Maximum Profit

P( $\sqrt{1100}$ ) = 3300 $\sqrt{1100}$ - 50000 - $\sqrt{1100} ^{3}$

= 3300(33.17) - 50,000 - 33.17³

= 109461 -50,000 - 36495.26

= 22,965.74

Maximum profit is 22,966 to the nearest whole number
