Answer:

FV= $10,342.64

Step-by-step explanation:

Giving the following information:

Initial Investment (PV)= $2,500

Interest rate (i)= 0.095/12= 0.00792

Number of periods (n)= 15*12= 180

To calculate the future value (FV), we need to use the following formula:

FV= PV*(1 + i)^n

FV= 2,500*(1.00792^180)

FV= $10,342.64

9514 1404 393

Answer:

  $1200.00

Step-by-step explanation:

The balance is given by the formula ...

  A = Pe^(rt) . . . . . principal P invested at annual rate r for t years

Using your numbers, we can find P to be ...

  P = Ae^(-rt) = $1720·e^(-0.045·8) = $1720·e^-0.36

  P ≈ $1200.00

Answer:

7 hours

Step-by-step explanation:

15 dollars +15 dollars 30 dollars=2 hours. 5 dollars left 15 divided by 3, 5 dollars. 3 divided by 3 = 1 so 1 hours is 5 dollars. My explaining is not good.

Answer: 7 hours

Step-by-step explanation:

She earns 5 dollars per hour because 5x3=15

and then you do 15x2=30

then 3x2=6

then just add 1 to 6

6+1=7

so there's your answer

7 hours

Answer:

The sequence converges to  infinity.

Step-by-step explanation:

[tex]a_n = \frac{n^3 - n}{n^2 + 5n}\\\\ \lim_{n \to \infty} a_n = \lim_{n \to \infty} \frac{n^3 - n}{n^2 + 5n}[/tex]

                [tex]= \lim_{n \to \infty} \frac{n(n^2 - 1)}{n(n + 5)} \\\\= \lim_{n \to \infty} \frac{(n^2 - 1)}{(n + 5)}\\\\= \lim_{n \to \infty} \frac{n(n - \frac{1}{n})}{n(1 + \frac{5}{n})}\\\\= \lim_{n \to \infty} \frac{(n - \frac{1}{n})}{(1 + \frac{5}{n})}[/tex]

[tex]denominator = \lim_{n \to \infty} 1 + \frac{5}{n} = 1 + \lim_{n \to \infty} \frac{5}{n} = 1+0 = 1[/tex]

[tex]numerator = \lim_{n \to \infty} n - \frac{1}{n} = \infty[/tex]

Therefore,

             [tex]\lim_{n \to \infty} a_n = \frac{ \infty}{1} = \infty[/tex]

The sequence diverges because the series divergence the limit tends to infinity does not exist option (A) is correct.

A series is convergent if the series of its partial sums approaches a limit; that really is, when the values are added one after the other in the order defined by the numbers, the partial sums get closer and closer to a certain number.

We have:

A sequence:

[tex]\rm a_n=\dfrac{\left(n^3-n\right)}{n^2+5n}[/tex]

As we know if the series converges the limit tends to infinity exist.

If the series divergence the limit tends to infinity does not exist.

Taking limit x tends to infinity:

[tex]\rm = \lim \:_{n\to \:\infty \:\:}\dfrac{\left n^3-n\right}{n^2+5n}[/tex]

[tex]\rm =\lim _{n\to \infty \:}\left(\dfrac{n^2-1}{n+5}\right)[/tex]

[tex]\rm =\lim _{n\to \infty \:}\left(\dfrac{n-\frac{1}{n}}{1+\dfrac{5}{n}}\right)[/tex]

[tex]\rm =\dfrac{\lim _{n\to \infty \:}\left(n-\dfrac{1}{n}\right)}{\lim _{n\to \infty \:}\left(1+\dfrac{5}{n}\right)}[/tex]

= ∞/1

= ∞  = does not exist.

Thus, the sequence diverges because the series divergence the limit tends to infinity does not exist option (A) is correct.

Solution :

The level of significance refers to the probability of the null hypothesis that may be rejected in the study by the observer. As the sample size increases, the p value also increases but the significance remains same. When the sample size increase and becomes large, the null hypothesis can be rejected more easily.

The business decisions are taken defending the significance level of the statistical validation in cases of uncertainty. Suppose the null hypothesis is the sales after the marketing campaigning remains same. The company will launch the marketing campaign when the confidence level is 95% so that after the campaign the sales will increase. It means that the significance level must be high enough for rejecting null hypothesis of sales post of the marketing campaign that remains same.

When the sample size increases, the sensitivity of hypothesis increases, and for a large sample, the hypothesis may be rejected even though it is true.

Step-by-step explanation:

To explain what 27 times 13 means, look at it as 27 added together 13 times. To get the answer, you could just write down the number 27, 13 times and then add the 27 numbers together.

If you have one of those old-fashioned handheld calculators, you can double check that the answer is 351 by pressing 27, then x, then 13, and then = to get the answer.

Answer:

[tex]351[/tex]

Step-by-step explanation:

[tex]27\times \:13[/tex]

Step 1: Line up the numbers; Multiply the top number by the bottom number one digit at a time starting with the ones digit (from right to left)

[tex]\begin{matrix}\space\space&2&7\\ \times \:&1&3\end{matrix}[/tex]

Step 2: Multiply the top number by the bolded digit of the bottom number

[tex]\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}[/tex]

Step 3: Multiply the bold numbers; Carry 2 to the column on the left and write 1 in the result line

[tex]7\times \:3=21\\\\\frac{\begin{matrix}\space\space&2&\space\space\\ \space\space&2&\textbf{7}\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&\space\space&1\end{matrix}}[/tex]

Step 4: Add the carried number to the multiplication

[tex]2+2\times \:3=8\\\\\frac{\begin{matrix}\space\space&\textbf{2}&\space\space\\ \space\space&\textbf{2}&7\\ \times \:&1&\textbf{3}\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]

Step 5: Multiply the top number by the bolded digit of the bottom number

[tex]\frac{\begin{matrix}\space\space&\textbf{2}&\textbf{7}\\ \times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&8&1\end{matrix}}[/tex]

Step 6: Multiply the bold numbers

[tex]7\times \:1=7\\\\\frac{\begin{matrix}\space\space&\space\space&2&\textbf{7}\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&\space\space&7&\space\space\end{matrix}}[/tex]

Step 7: Multiply the bold numbers

[tex]2\times \:1=2\\\\\frac{\begin{matrix}\space\space&\space\space&\textbf{2}&7\\ \space\space&\times \:&\textbf{1}&3\end{matrix}}{\begin{matrix}\space\space&\space\space&8&1\\ \space\space&2&7&\space\space\end{matrix}}[/tex]

Step 8: Add the rows. Add zero for simplicity

[tex]\frac{\begin{matrix}\space\space&\space\space&2&7\\ \space\space&\times \:&1&3\end{matrix}}{\begin{matrix}\space\space&0&8&1\\ \space\space&2&7&0\end{matrix}}[/tex]

[tex]81 + 270 = 351[/tex]

Therefore 27 times 3 is 351

Answer:

f(x)=x^2+4x-21

Step-by-step explanation:

Answer:

f(x) = (x + 7)  (x - 3)

Step-by-step explanation:

f(x)=(x+[tex]2)^{2}[/tex]-25

(x + 7) (x - 3) we put the 2 x's because of the (x+2)^2

now the + 7 and - 3, multiply the 2 numbers = -21 then use those 2 in

(x+2)^2 to add for the answer = -25

Answer:

on the 5th week they would both have the same amount of money they would both have a total of 85$

Step-by-step explanation:

The number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

The solution of the equation means the value of the unknown or variable.

Let x be the number of the weeks and y be the total amount.

Michelle and Pierre both want to buy guitars, Michelle has already saved $60, and plans to save $5 per week until she can buy the guitar, Pierre has $25, and plans to save $12 per week.

Then the equations will be

y = 5x + 60    ....1

y = 12x + 25  ....2

Subtract equation 1 from equation 2. Then we have

7x – 35 = 0

       7x = 35

         x = 5 weeks

Then the number of weeks will pass before Michelle and Pierre have the same amount of money will be 5.

Answer:

Simplifying radicals is the process of manipulating a radical expression into a simpler or alternate form. Generally speaking, it is the process of simplifying expressions applied to radicals.

Estimation (or estimating) is the process of finding an estimate, or approximation, which is a value that is usable for some purpose even if input data may be incomplete, uncertain, or unstable. The value is nonetheless usable because it is derived from the best information available.

Step-by-step explanation:

The radical symbol represents the root of a number and is read as x radical n or the nth root of x.

The symbol " that expresses a number's root is known as radical, and it is read as x radical n or the nth root of x. The horizontal line that surrounds the number is known as the vinculum, and the number beneath it is known as the radicand. The index or degree is the number n written before the radical.

The process of transforming a radical expression into a simpler or alternate form is known as simplifying radicals. In general, it is the process of simplifying expressions that are applied to radicals.

Estimation (or estimating) is the process of determining an estimate, or approximation, which is a value that can be used for a specific purpose despite the fact that the input data may be incomplete, uncertain, or unstable. The value is still useful because it is based on the best available information.
