6.1). the rate of depreciation, r, is approximately 10.77%.

6.2.1). Ncominkosi's monthly installment amount was approximately R 10,505.29.

6.2.2).  Ncominkosi borrowed approximately R 377,510.83 from the bank.

6.1) Let's assume the original price of the laptop is P. According to the reducing balance method, the value of the laptop after 4 years can be calculated as P * (1 - r/100)^4. We are given that this value is 31% of the original price, so we can write the equation as P * (1 - r/100)^4 = 0.31P.

Simplifying the equation, we get (1 - r/100)^4 = 0.31. Taking the fourth root on both sides, we have 1 - r/100 = ∛0.31.

Solving for r, we find r/100 = 1 - ∛0.31. Multiplying both sides by 100, we get r = 100 - 100∛0.31.

Therefore, the rate of depreciation, r, is approximately 10.77%.

6.2.1) To determine the monthly installment amount, we can use the formula for calculating the monthly payment on a loan with compound interest. The formula is as follows:

\(P = \frac{r(PV)}{1-(1+r)^{-n}}\)

Where:

P = Monthly payment

PV = Loan principal amount

r = Monthly interest rate

n = Total number of monthly payments

Let's calculate the monthly installment amount for Ncominkosi's loan:

Loan amount = Total amount paid to the bank - Interest

Loan amount = R 596,458.10 - R 0 (No interest is deducted from the total paid amount since it is the total amount paid)

Monthly interest rate = Annual interest rate / 12

Monthly interest rate = 9.5% / 12 = 0.0079167 (rounded to 7 decimal places)

Number of monthly payments = 6 years * 12 months/year = 72 months

Using the formula mentioned above:

\(P = \frac{0.0079167(Loan Amount}{1-(1+0.0079167)^{-72}}\)

Substituting the values:

\(P = \frac{0.0079167(596458.10}{1-(1+0.0079167)^{-72}}\)

Calculating the value:

P≈R10,505.29

Therefore, Ncominkosi's monthly installment amount was approximately R 10,505.29.

6.2.2) To determine the amount of money Ncominkosi borrowed from the bank, we can subtract the interest from the total amount he paid to the bank.

Total amount paid to the bank: R 596,458.10

Since the total amount paid includes both the loan principal and the interest, and we need to find the loan principal amount, we can subtract the interest from the total amount.

Since the interest rate is compounded monthly, we can use the compound interest formula to calculate the interest:

\(A=P(1+r/n)(n*t)\)

Where:

A = Total amount paid

P = Loan principal amount

r = Annual interest rate

n = Number of compounding periods per year

t = Number of years

We can rearrange the formula to solve for the loan principal:

\(P=\frac{A}{(1+r/n)(n*t)}\)

Substituting the values:

Loan principal (P) = \(\frac{596458.10}{(1+0.095/12)(12*6)}\)

Calculating the value:

Loan principal (P) ≈ R 377,510.83

Therefore, Ncominkosi borrowed approximately R 377,510.83 from the bank.

The last digit of the product of all the numbers between 11 and 29 is 0.

A product is something that has undergone one or more multiplications.

Here, we're looking for the final digit of the product of all whole numbers greater than 11 and less than 29.

Next, we have the product as: 12*13*14*15*16*17*18*19*20*21*22*23*24*25*26*27*28

Now take note of the 20 that is present.

Any number multiplied by 20 will result in a zero, so:

Product = 20*(12*13*14*15*16*17*18*19*21*22*23*24*25*26*27*28)

Step-by-step explanation:

n^2 has a factor of 18, so factors of 3^2·2. Since n^2 is a perfect square, we know n must have a factor of 3·2 = 6.

n^3 has a factor of 640, so factors of 2^7·5. Since n^3 is a perfect cube, we know n must have a factor of 2^3·5 = 40.

The least common multiple of 6 and 40 is 120.

The smallest positive integer n is 120.

Answer:

45

Step-by-step explanation:

arcAE = 180

arcABC : arcCDE = 3:1

ABC:CDE = 135:45

∠T = 1/2(135 - 45) = 45

Use the Far Arc -- Near Arc Formula:  m∠T = 1/2(far-arc - near-arc) = 1/2(arcABC -arcCDE)

so let's recall that a full circle has a total of 360°, and we also know that these two arcs are on 3 : 1 ratio.

Now, let's notice the points A and E, the line AE passes through the center of the circle, that means the arc made by ABCE is half the circle or 180°.

So if we just divide 180 by (3 + 1) and then distribute accordingly to each arc, we'll see how many degrees each arc really has

\(\stackrel{\widehat{ABC}}{3}~~ : ~~\stackrel{\widehat{CDE}}{1}\qquad \implies \qquad \stackrel{\widehat{ABC}}{3\cdot \frac{180}{3+1}}~~ : ~~\stackrel{\widehat{CDE}}{1\cdot \frac{180}{3+1}} \\\\\\ \stackrel{\widehat{ABC}}{3\cdot 45}~~ : ~~\stackrel{\widehat{CDE}}{1\cdot 45}\qquad \implies \qquad\stackrel{\widehat{ABC}}{135}~~ : ~~\stackrel{\widehat{CDE}}{45}\)

Check the picture below.

We are asked to draw the following angle

Let us first convert this angle to degrees

So the angle is negative 470°

For positive angle, we need to draw in the counterclockwise direction

For negative angle, we need to draw in the clockwise direction

Recall that 360° is one complete rotation and 470° - 360° = 110°

Recall that 90° is equal to one quadrant so 110° - 90° = 20°

So, we need to draw one complete rotation plus one quadrant plus 20° in the clockwise direction.

The graphs of the tangent, cotangent, secant, and cosecant function all have vertical asymptotes.

Vertical asymptotes are vertical lines that the graphs approach but never touch or cross. These asymptotes occur at points where the functions become undefined or have a vertical discontinuity.

For the tangent function (tan(x)), the vertical asymptotes occur at x-values where the cosine function (cos(x)) equals zero. Since cos(x) is zero at every multiple of π/2, the tangent function has vertical asymptotes at x = π/2, 3π/2, 5π/2, and so on.

Similarly, for the cotangent function (cot(x)), the vertical asymptotes occur at x-values where the sine function (sin(x)) equals zero. Since sin(x) is zero at every multiple of π, the cotangent function has vertical asymptotes at x = π, 2π, 3π, and so on.

The secant function (sec(x)) and cosecant function (csc(x)) are reciprocal functions of the cosine and sine functions, respectively. Therefore, their graphs also have vertical asymptotes at the same x-values where the cosine and sine functions equal zero.

In conclusion, the graphs of the tangent, cotangent, secant, and cosecant function all have vertical asymptotes.

For this function, A is -2/3, B is 0 and C is 2/3.

To find the critical numbers of the function f(x) = 9x + 4\(x^{-1}\) , we need to find the values of x where the derivative of the function is equal to zero or undefined.

The derivative of f(x) is:

f'(x) = 9 - 4\(x^{-2}\) = 9 - 4/\(x^{2}\)

To find where the derivative is equal to zero, we set f'(x) = 0 and solve for x:

9 - 4/\(x^{2}\)  = 0

4/\(x^{2}\)  = 9

\(x^{2}\) = 4/9

x = ±2/3

Therefore, the critical numbers of f(x) are x = 2/3 and x = -2/3.

To find the intervals where the function is not defined, we need to look for values of x that make the denominator of the expression 4\(x^{-1}\)  equal to zero. In this case, the function is not defined at x = 0.

Now we need to determine the sign of the derivative in each of the intervals (−∞,A], [A,B), (B,C], and [C,∞).

For x < -2/3, f'(x) is negative because 4/\(x^{2}\)  is positive and 9 is greater than 4/\(x^{2}\) . Therefore, the function is decreasing on the interval (−∞,−2/3).

For −2/3 < x < 0, f'(x) is still negative because 4/\(x^{2}\)  is positive and 9 is still greater than 4/\(x^{2}\) . Therefore, the function is decreasing on the interval (−2/3,0).

For 0 < x < 2/3, f'(x) is positive because 4/\(x^{2}\)  is positive and 9 is less than 4/\(x^{2}\) . Therefore, the function is increasing on the interval (0,2/3).

For x > 2/3, f'(x) is still positive because 4/\(x^{2}\)  is positive and 9 is still less than 4/\(x^{2}\) . Therefore, the function is increasing on the interval (2/3,∞).

Finally, the function is not defined at x = 0, so the interval [A,B) is (−∞,0) and the interval (B,C] is (0,∞).

Therefore, we have:

A = -2/3

B = 0

C = 2/3

Given: An urn containing 5 red, 3 blue, and 2 orange marbles in it.

To find:

What is the probability that the first marble you draw is blue?

Total number of marbles in the urn= 5+3+2 = 10 Probability of the first marble being blue = Number of blue marbles/Total number of marbles= 3/10Therefore, the probability that the first marble you draw is blue is 3/10.Suppose you drew a blue marble in the first draw. If drawing with replacement.

What is the probability of drawing a blue marble in the second draw?

When we are drawing with replacement, the urn is filled back with marbles after every draw. Hence, the number of marbles remains the same in every draw. The probability of drawing a blue marble in the first draw = 3/10Therefore, in the second draw also, the probability of drawing a blue marble is 3/10.So, the probability of drawing a blue marble in the second draw when drawing with replacement, given that a blue marble was drawn in the first draw is 3/10.Suppose you instead drew an orange marble in the first draw. If drawing with replacement.

what is the probability of drawing a blue marble in the second draw?

The probability of drawing an orange marble in the first draw = Number of orange marbles/Total number of marbles= 2/10= 1/5In the second draw, the urn is filled back with marbles and the total number of marbles remains the same. The probability of drawing a blue marble in the second draw= Number of blue marbles/Total number of marbles= 3/10Therefore, the probability of drawing a blue marble in the second draw, given that an orange marble was drawn in the first draw, when drawing with replacement, is 3/10. If drawing with replacement.

When we draw with replacement, the probability of drawing a blue marble is 3/10 for every draw. As we are drawing with replacement, each draw is an independent event. The probability of drawing two blue marbles in a row = (Probability of the first marble being blue) × (Probability of the second marble being blue) = (3/10) × (3/10)= 9/100Therefore, the probability of drawing two blue marbles in a row when drawing with replacement is 9/100.

Yes, when we draw with replacement, the draws are independent. This is because the urn is filled back with marbles of the same kind after each draw. Hence, the probability of drawing a certain color remains the same in every draw. Therefore, every draw is an independent event.

The finite population correction factor is used in computing the standard error of the sample mean when the sample size is smaller than 5% of the population size.

The finite population correction factor is a adjustment made to the standard error of the sample mean when the sample is taken from a finite population, rather than an infinite population.

It accounts for the fact that sampling without replacement affects the variability of the sample mean.

When the sample size is relatively large compared to the population size (more than half), the effect of sampling without replacement becomes negligible, and the finite population correction factor is not necessary.

In this case, the standard error of the sample mean can be estimated using the formula for sampling with replacement.

On the other hand, when the sample size is small relative to the population size (less than 5%), the effect of sampling without replacement becomes more pronounced, and the finite population correction factor should be applied.

This correction adjusts the standard error to account for the finite population size and provides a more accurate estimate of the variability of the sample mean.

Therefore, the correct answer is option 2: the finite population correction factor is used when the sample size is smaller than 5% of the population size.

Nonresponse bias occurs when individuals who choose not to participate in a survey differ in important ways from those who do participate, leading to potential distortions in the survey results. In this case, the suspicion of the volunteers expressed by some people influences their decision not to participate, resulting in a nonresponse bias.

To determine the extent of nonresponse bias, researchers typically compare the characteristics of the respondents and non-respondents. If the non-respondents significantly differ from the respondents in terms of demographic factors, attitudes, or other relevant variables, it suggests the presence of nonresponse bias.

In this particular scenario, the suspicion expressed by certain individuals towards the volunteers leads them to opt out of participating in the survey. This introduces nonresponse bias, as the survey results may not accurately represent the opinions and characteristics of the entire population being surveyed.

The best description of how close the prediction was to the actual population in 2013 is option (A) with in 100 people

To solve this problem, we can use the exponential growth formula:

P(t) = P0 × e^(rt)

where P(t) is the population at time t, P0 is the initial population, r is the growth rate, and e is the mathematical constant approximately equal to 2.718.

We can use the given data to find the growth rate r:

58,000 = 42,000 × e^(r×30)

Dividing both sides by 42,000:

e^(r×30) = 58,000/42,000 = 1.38

Taking the natural logarithm of both sides:

r×30 = ln(1.38)

r = ln(1.38)/30

r ≈ 0.0106

Now we can use this growth rate to predict the population in 2013:

P(53) = 42,000 × e^(0.0106×53) ≈ 74,480

So the predicted population of 74,480 is within 520 people of the actual population of 75,000

4. AB and DE are congruent. (Opposite sides of a parallelogram are congruent)

5. ΔABE and ΔDEA are congruent by ASA (Angle-Side-Angle) congruence. (Corresponding parts of congruent triangles are congruent)

6. CPCTC (Corresponding Parts of Congruent Triangles are Congruent)

7. AE and BD bisect each other. (Congruent corresponding parts of congruent triangles)

The proof begins by stating that ABCD is a parallelogram. This implies that opposite sides are parallel and congruent. Using the alternate interior angles theorem, it is shown that the angles ∠ABE and ∠EDA are congruent. Then, the congruence of sides AB and DE is established based on the property that opposite sides of a parallelogram are congruent. By proving that ΔABE and ΔDEA are congruent using the ASA congruence criterion, it follows that corresponding parts of congruent triangles are congruent (CPCTC). Finally, it is concluded that the diagonals AE and BD bisect each other.
