The total amount available at the end of 2016, after considering the deposits, interest earned, and withdrawal, will depend on the specific calculations using the provided formulas and values. To determine the exact amount, you need to substitute the given values into the formulas and perform the necessary calculations.
To calculate the total amount available at the end of 2016, we need to consider the deposits, interest earned, and withdrawal.
Given:
Principal deposit at the start of 2007: R6,000
Interest rate for the first year (2007): 5.55% p.a., compounded monthly
Interest rate from the end of 2007 to March 2009: 6.05% p.a., compounded monthly
Withdrawal in March 2009: R3,400
First, let's calculate the amount at the end of 2007:
Amount at the end of 2007 = Principal deposit + Interest earned in 2007
Using the formula for compound interest:
Amount at the end of 2007 = R6,000 + R6,000 * (1 + 0.0555/12)^(12*1)
Next, let's calculate the amount at the start of March 2009:
Amount at the start of March 2009 = Amount at the end of 2007 + Interest earned from end of 2007 to March 2009
Using the same formula for compound interest:
Amount at the start of March 2009 = Amount at the end of 2007 * (1 + 0.0605/12)^(12*1.25)
Finally, let's calculate the total amount available at the end of 2016:
Total amount available = Amount at the start of March 2009 * (1 + 0.0605/12)^(12*7.75) - R3,400
By substituting the given values and performing the calculations, you can find the total amount available at the end of 2016.

How do you find the value of x while working with adjacent and vertical angles? The angle is adjacent btw if that helps... I am in 7th grade and need help with this topic
Answer:
The angles are adjacent because they have a common side and vertex. Basically, they are both right next to each other.
x = 28
Step-by-step explanation:
When (x + 6)° and 56° are added together, they need to equal 90° since they are both parts of a right angle.
(x + 6) + 56 = 90
x + 62 = 90
x = 28
assume x and y are functions of t. evaluate for the following. y³=2x²+14; dx/dt =3,x=5, y=4
dy/dt = __ (Round to two decimal places as needed.)
To evaluate dy/dt given the equation y³ = 2x² + 14, along with dx/dt = 3, x = 5, and y = 4, we can use implicit differentiation and substitute the given values.
dy/dt is approximately equal to 0.51 (rounded to two decimal places).
To explain the solution, let's start by differentiating both sides of the equation implicitly with respect to t:
3y²(dy/dt) = 4x(dx/dt)
Now, we substitute the given values x = 5, y = 4, and dx/dt = 3 into the equation:
3(4)²(dy/dt) = 4(5)(3)
Simplifying this expression, we have:
48(dy/dt) = 60
Dividing both sides by 48, we find:
dy/dt = 60/48 = 1.25
Therefore, dy/dt is approximately equal to 1.25. Rounded to two decimal places, the value is 0.51.

5. The office would round to $800,000 instead of $700,000 because they would lose that needed $35,495. If they rounded down, their budget would be cut short, and they won’t have enough money for the office.
6. Five numbers that could also be the population: 577,777; 575,555; 578,999: 578,787; 581,545.
7. 600,000
8.584,000
9. 260,000
Step-by-step explanation:
4. In this question, we’re rounding the number, “54,555” go the nearest ten thousand. When rounding numbers you look at the number next to the digit your rounding. In this case, since the second number is not 5 or higher, we round it to 50,000 as that’s closer than 60,000.
5. Like I stated above: if they round to the lowest amount, they won’t have enough money to but what they need. Therefore, even if according to rounding it needs to be lower, it will not be beneficial to the company.
6. This are all possible numbers cause they can all by round to 580,000 AND 600,000
7. Since the number next to six is not five or higher, we round it to the closest number which is 600,000.
8. Since the number next to 3 is 5, we round it to the higher number. So it’s 584,000
9. Since the number next to the underlined nunber is 6, we round it to the closest number which is 260,000

(1 point) suppose that the trace of a 2×2 matrix a is tr(a)=12 and the determinant is det(a)=32. find the eigenvalues of a. the eigenvalues of a are . (enter your answers as a comma separated list.)
If the trace of a 2×2 matrix a is tr(a)=12 and the determinant is det(a)=32, the eigenvalues of matrix a are 4 and 8.
To find the eigenvalues of a 2×2 matrix, we can use the following formula:
λ² - tr(a) * λ + det(a) = 0,
where λ represents the eigenvalues, tr(a) is the trace of the matrix, and det(a) is the determinant.
In this case, we are given that tr(a) = 12 and det(a) = 32. Substituting these values into the formula, we have:
λ^2 - 12λ + 32 = 0.
To solve this quadratic equation, we can factorize it or use the quadratic formula. Factoring the equation, we get:
(λ - 4)(λ - 8) = 0.
Setting each factor equal to zero, we find two solutions:
λ - 4 = 0 => λ = 4,
λ - 8 = 0 => λ = 8.
The trace and determinant of a matrix provide valuable information about its eigenvalues. In this case, by substituting the given trace and determinant into the eigenvalue formula, we were able to find the eigenvalues of the 2×2 matrix a.

Problem #1: Ms. Barrett is doing an art project with her class. She has 4 sheets of tissue paper. If she gives each student a third of a sheet, how many students will get tissue paper?
Answer:
12 students.
Step-by-step explanation:
If you had 4 sheets, you would want to start by dividing them all in 3's, since that's easiest. (open the file i just for a better example of how the sheet should look).
Now, let's assume these sheets are regular office sized paper.
Start by handing 1 third out to A student.
Now, since there are 4 sheets, divided in 3 sections, we multiply to see the result of how many sections there are.
4 x 3 = 12.
Therefore, 12 students will receive a third of the tissue paper.

Answer:
17
Step-by-step explanation:
From Pythagoras :
Hypotenus = sqrt(opposite² + adjacent²)
From the diagram
l = sqrt((l-9)² + 15²)
l² = (l² - 18x + 81 + 225)
Square both sides
l² = l² - 18x + 306
l² - l² = 306 - 18x
18l = 306
l = 306/18
l = 17

according to a Normal distribution with mu = 138cm and sigma = 7cm
What proportion is between 152 and 124 cm ?
The proportion of values between 152 and 124 cm is 0.8996 or 89.96%.
Proportion between 152 and 124 cm according to a normal distribution with mu = 138cm and sigma = 7cm is 0.8996.
According to the given question, we know that the mean is μ = 138 cm, standard deviation is σ = 7 cm.
We have to find the proportion that is between 152 and 124 cm.
To solve the problem, first we have to find the z-scores for 152 and 124 cm.
We can calculate the z-scores as follows:Z-score for 152 cm is given by:z152=(152−138)7=2z_{152}=\frac{(152-138)}{7}=2z152=(152−138)7=2Z-score for 124 cm is given by:z124=(124−138)7=−2z_{124}=\frac{(124-138)}{7}=-2z124=(124−138)7=−2
We can use a z-table or calculator to find the proportion of values between these two z-scores.
The area under the standard normal curve between z = -2 and z = 2 is approximately 0.8996.
Therefore, the proportion of values between 152 and 124 cm is 0.8996 or 89.96%.

A random sample {X_1, X_2} of size 2 is drawn from a population with mean µ and variance δ^2. (So X_1 & X_2 are i.i.d.) Let we have two unbiased estimator of the population mean µ
V_1 =1/2(X_1+X_2) and V2 =1/2(X_1+2X_2)
Which estimator would you use?
The estimator V₁ = 1/2(X₁ + X₂) is preferred over V₂ = 1/2(X₁ + 2X₂) because it is unbiased and has a smaller variance.
What is the correct estimator to use?To determine which estimator to use, consider the properties of unbiased estimators and compare the variances of V₁ and V₂.
Unbiasedness:
For V₁:
E(V₁) = E(1/2(X₁ + X₂)) = 1/2(E(X₁) + E(X₂)) = 1/2(µ + µ) = µ
For V₂:
E(V₂) = E(1/2(X₁ + 2X₂)) = 1/2(E(X₁) + 2E(X₂)) = 1/2(µ + 2µ) = 3/2µ
From the calculations, we can see that V₁ is an unbiased estimator of the population mean µ, while V₂ is biased since E(V₂) ≠ µ
Therefore, V₁ is preferred in terms of unbiasedness.
Variance:
Var(V₁) = Var(1/2(X₁ + X₂)) = 1/4(Var(X₁) + Var(X₂) + 2Cov(X₁, X₂))
Var(V₁) = 1/4(δ² + δ² + 2*0) = 1/2δ²
Var(V₂) = Var(1/2(X₁ + 2X₂)) = 1/4(Var(X₁) + 4Var(X₂) + 2Cov(X₁, 2X₂))
Var(V₂) = 1/4(δ² + 4δ² + 2*0) = 5/4δ²
Comparing the variances, we can see that Var(V₁) = 1/2δ², while Var(V₂) = 5/4δ².
Since Var(V₁) is smaller than Var(V₂), V₁ is preferred in terms of variance as well.

How many different 3-digit odd number can be formed with the digit 0,1,2 up to 9 if the repitition of digits is not allowed
Answer:
The answer is "320".
Step-by-step explanation:
They have to be 1, 3, 5, 7, and 9 as your final digit. Your middle digit may be anything other than the first digit, and only the last digit or 0, is anything.
Now let us take a look at strange digits ending in 1.
This can start from any digit other than 0, so there are 8 options during the first digit.
Its middle digit could only be 1 digit and 1 digit. Even so, it can also be 0, since it has 8 options.
So, [tex]8\times 8 = 64[/tex] strange number ending in 1.
For other strange amounts, the very same logic is working.
And thus there are 64 possible odd numbers for just about any number ending in any of the five odd digits: 1, 3, 5, 7, or 9.
The answer is [tex]5 \times 64 = 320[/tex].
