Since it decreases by 10% we have to write 0.9. The correct answer is A because it is the only one with the principal of 24,000 and has a 0.9 decrease.

Part2:
you put 5 where the x is and you get
$14,171.76

It will be A bc youre multiplying the total amount of the car by how much it is worth. If it is decreasing by 10% each year then it is worth 90% of its value, hence 0.9

Answer:

Step-by-step explanation:

Rationalize the denominator of b. So, multiply the numerator and denominator by $\sqrt{x}$

$b = \frac{(1-2\sqrt{x}) *\sqrt{x}}{\sqrt{x}*\sqrt{x} }=\frac{1*\sqrt{x} -2\sqrt{x} *\sqrt{x} }{\sqrt{x} *\sqrt{x} }\\\\=\frac{\sqrt{x} -2x}{x}\\$

Now, find a +b

$a +b = \frac{2x+\sqrt{x} }{x}+\frac{\sqrt{x} -2x}{x}\\\\=\frac{2x+\sqrt{x} +\sqrt{x} -2x}{x}$

Combine like terms

$= \frac{2x-2x+\sqrt{x} +\sqrt{x} }{x}\\\\=\frac{2\sqrt{x} }{x}$

Now find (a + b)²

(a +b)² = $(\frac{2\sqrt{x} }{x})^{2}$

$= \frac{2^{2}*(\sqrt{x} )^{2}}{x^{2}}\\\\= \frac{4* x}{x^{2}}\\\\= \frac{4}{x}$

Hint: $\sqrt{x} *\sqrt{x} =\sqrt{x*x}=x$

Company fixed cost = $10 million = $10,000,000

Variable cost per pair = $5

Company charges each pair = $15

Hence the company makes $10 profit per pair regardless the company fixed cost and only considering the variable cost.

Let subtract the variable cost per pair from the company charging each pair = 15 - 5 = $10

Thus the company now makes $10 per pair, and it has to sell 1,000,000 pairs of gloves to reach the break-even point. The break-even point refers to the point where total cost and revenue are equal.

<span>Thus for 1,000,000 pairs, the company total earning = 10 x 1,000,000 = $10,000,000 = $10 million </span>

Nataly_w [17]

Answer:

Step-by-step explanation:

Expected value of the bet =

<h3>P(you make the correct draw) * 40 + P(you do not make the correct draw) * (-10) = </h3>

(4/52)(4/51)(4/50) * 40 + (1 - (4/52)(4/51)(4/50)) * (-10) =

(64/132600) * 40 + (1 - 64/132600) *(-10) =

64/3315 + (132536/132600) * (-10) =

64/3315 - (132536/13260) =

64/3315 - 33134/3315 =

-33070/3315 =

-9.97586726998 =

-$9.98, rounded to the nearest cent

(i.e., the expected value of the bet is a loss of $9.98)
