If the flotation costs are 2 percent of gross proceeds, and gross proceeds are $250,000, what is the dollar amount of flotation

alina1380 [7]

The dollar amount of the flotation costs by percent of gross proceeds is $5,000

We need to know about the percent theory first, percent is per 100. So when A is 1% of B it means that

A = 1/100 x B

From the question, we know that

The gross proceeds is given by = $250,000 and

the flotation cost is given by = 2% of gross proceeds.

We can write the flotation cost as

Flotation cost = 2/100 x $250,000

Flotation cost = 2/100 x $250,000

Flotation cost = $5,000

Hence, the dollar amount of the flotation costs is $5,000

What can I do to get y alone on one side of the equation

Anika [276]

Answer:

All you have to do is subtract or add the numbers that are not the variable, y, on both sides to get the variable, y, on one side of the equation. Then, if there is a number in front of it, you must divide that number on both sides.

Step-by-step explanation:

All you have to do is subtract or add the numbers that are not the variable, y, on both sides to get the variable, y, on one side of the equation. Then, if there is a number in front of it, you must divide that number on both sides.

Anastaziya [24]

Answer:

e. m = 16.2; s = 1.27

Step-by-step explanation:

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we can assume that the distribution for X is given by:

$X \sim Binom(n=18, p=0.9)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Normal approximation

We need to check the condition in order to use the normal approximation.

$np=18*0.9=16.2 \geq 10$

So we see that we satisfy the condition and then we can apply the approximation.

If we appply the approximation the new mean and standard deviation are:

$E(X)=np=18*0.9=16.2$

$\sigma=\sqrt{np(1-p)}=\sqrt{18*0.9(1-0.9)}=1.273$

The best answer would be:

e. m = 16.2; s = 1.27

Which of the following is a factor of 1331x3 − 8y3?

Cloud [144]

Answer:

The factor is 11x - 2y ⇒ 2nd answer

Step-by-step explanation:

* Lets explain how to factorize the difference of two cubes

- If we want to factorize x³ - y³

- The binomial x³ - y³ is different of two cubes, because x³ is cube x

and y³ is cube y

- The difference of two cubes has two factors one two two terms and

the other is three terms

- To factorize it we find the ∛x³ and ∛y³

→ ∛x³ = x and ∛y³ = y

→ Then the first factor is (x - y)

→ We find the second factor from the first factor

→ square x

→ square y

→ Multiply x and y and put them between x² and y² with opposite sign

of the first factor

→ The second factor is (x² + xy + y²)

* Lets do the same with 1331x³ - 8y³

∵ $\sqrt[3]{1331x^{3}}=11x$

∵ $\sqrt[3]{8y^{3}}=2y$

∴ The first factor is (11x - 2y)

∵ (11x)² = 121x²

∵ (2y)² = 4y²

∵ 11x × 2y = 22xy

∵ The sign of first factor is (-)

∴ The second factor is (121x² + 22xy + 4y²)

∴ <em>The factor is 11x - 2y </em>
