$9483.774 money should be deposited in the account.

Let the amount to be invested be P=$x so that the amount accumulated is A = $12000. We have t=3 years. The rate of interest is r=0.04 per year.     n  = 2 as interest will be compounded twice a year.

Interest, in its most simple form, is calculated as a percent of the principal.

Interest is the amount of money a lender or financial institution receives for lending out money. Interest can also refer to the amount of ownership a stockholder has in a company, usually expressed as a percentage.

Now,

                         [tex]x (1 + \frac{0.04}{2} )^{2 * 3}[/tex] [tex]= 12000[/tex]

                                 [tex]x(1.04)^{6}[/tex] [tex]= 12000[/tex]

                                           [tex]x = \frac{12000}{(1.04)^{6} }[/tex]

                                              ≈ 9483.774

The difference between the numbers 4.7 and 2.3 is 2.4

what is number line ?

The visual representation of numbers on a straight line is called a number line. On an endless line that extends on both sides, either horizontally or vertically, this line is used to compare numbers that are spaced at equal intervals. The numbers on a horizontal number line grow as we approach towards the right side and drop as we move towards the left.

Between 4 and 5 , there are 10 divisions. Each division shows the value 0.1.

So, 4.7 is marked as shown in the figure.

To find the difference 4.7 - 2.3 , reverse the direction by 2.3 units from 4.7, will give us 2.4..

The mean score is 6.48. If we were to give this quiz to more and more students, the mean score for these students would approach 6.48.

Probability is a measure of the likelihood of an event occurring. It is a number between 0 and 1, with 0 representing an impossible event and 1 representing a certain event. The probability of an event is calculated by dividing the number of ways the event can occur by the total number of possible outcomes.

To find the mean score, we need to calculate the expected value of the score. The expected value is calculated by multiplying the score by its probability and summing over all possible scores.

The expected value is:

(5 * 0.06) + (6 * 0.18) + (7 * 0.37) + (8 * 0.22) + (9 * 0.11) + (10 * 0.06) = 6.48

Total $234.95 is the cost of 5 band shirts and 5 pair of pants.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given, Molly bought 4 band shirts and 3 pair of pants for $159.99.

And Christian bought 3 band shirts and 2 pair of pants for $113.00.

Let x be the band shirts and y be the pair of pants.

So, according to the question;

4x + 3y = 159.99         equation 1

3x + 2y = 113                equation 2

Now, we have the system of the equations.

In order to solve the system of equations:

Multiply 4 to the equation 2 and multiply 3 to the equation 2.

12x + 9y = 479.97

12x + 8y = 452

Subtracting the transformed equation 2 to transformed equation 1.

y = 27.97

Then 12x = 479.97 - 251.73

 12x = 228.24

x = 228.24 / 12

x = 19.02.

To find the amount of 5 band shirts and 5 pair of pants:

5x + 5y

= 5 (19.02) + 5(27.97)

= 95.1 + 139.85

= 234.95

y = 0  ..........(1)

Put values of 'y' in equation (1), and we get.

(x-12)³ - 7 = 0         .........(2)
Adding '7' on both sides of equation (2), we get

(x-12)³ = 7
Taking the cube root on sides, the resulting equation will be:

As per the given question,

For 68% confidence,

                                z ( α / 2 )   =   0.9944

Substitute the values in 1,

E   =   z ( α / 2 )  ×  σ / √n

     =   0.9944  ×  20 / √100

     =   0.9944  ×  20 / 10

E    =   1.9888   ≅   1.99

Let us consider,

⇒   x  -  E     <     μ     <     x  +  E

⇒   195  -  1.99     <     μ     <     195  +  1.99

The shape of the sampling distribution of the mean for samples of size 45 will be normal.

This is because the sampling distribution of the mean approaches normality as the sample size increases. The center of the sampling distribution will be 67 inches, which is the mean height of the population. The spread of the sampling distribution will be determined by the standard deviation of the population and the sample size. Specifically, the standard deviation of the sampling distribution will be equal to the standard deviation of the population divided by the square root of the sample size. In this case, the standard deviation of the sampling distribution will be 3.8 inches / sqrt(45) = 0.55 inches.

A rectangle measures 75 cm by 15 cm.Find the length of the perimeter?

P = (75 + 15) x 2

P = 90 x 2

P = 180 cm

Answer:

The correct answer is (1, -3).

Step-by-step explanation:

To solve this question, we should use substitution. This means we can substitute the value given for y (as indicated by the second equation) into the first equation. This is shown below:

4x + y = 1

4x + (x - 4) = 1

We simplify the left side of the equation and then solve for x.

5x - 4 = 1

5x = 5

x = 1

We must also solve for y. To do this, we can plug in x = 1 into either of the given equations.

y = x - 4

y = 1 - 4

y = -3

Therefore, x = 1 and y = -3. The question asks us to express the answer as an ordered pair (x,y), so the answer is (1, -3).
