Two years ago, an investment of R1 500000 has increased to R1 700000 and has delivered R40 000 worth of dividends over the two years. Then the return on investment would be 16%.

We can use the following formula to calculate ROI:

ROI = (gain from investment - cost of investment) / cost of investment

where, gain from investment is the total value of the investment (including dividends), and cost of investment is the initial investment.

Using the values given in the question, we can calculate the ROI as:

ROI = ((R1,700,000 + R40,000) - R1,500,000) / R1,500,000 = R240,000 / R1,500,000

ROI = 0.16 or 16%

Therefore, the return on the investment is 16%.

Based on simple interest, the solution to the question is that his friend will ultimately owe Darrel $2,875.

A loan or investment's interest can be calculated using simple interest using the principal, interest rate, and duration of the transaction. Because it just considers the original principal and does not account for any compounded interest, it is known as "simple" interest.

Darrel will be indebted to his friend for the following sum if he lends him $2,500 and receives repayment with 15% simple interest after a year:

Interest = Principal x Rate x Time

Interest = $2,500 x 0.15 x 1

Interest = $375

Thus, the total sum his friend will be required to pay Darrel is:

Total amount = Principal + Interest

Total amount = $2,500 + $375

Total amount = $2,875

Thus, the total amount his friend owes Darrel is $2,875.

We can see here that the best way to describe the center of the data represented in this line plot is:

The median is between 4 and 5.

A line plot, often called a dot plot, is a simple type of data visualisation that makes use of dots and a number line to show how frequently certain values appear in a data set.

Line plot offers a visual representation of the distribution and enables speedy evaluation of the central tendency and variability of the data.

When displaying small to medium-sized data sets and giving a visual representation of the distribution and clustering of values, line plots are very helpful. They make it simple to spot any outliers or unexpected data as well as the most frequent or frequently occurring numbers.

The ∆ABC has been transformed to yield ∆A'B'C'. The fourth diagram shows that the transformation could NOT be achieved by rotation alone.

The diagram is attached with the answer below:-

Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

In the first figure, ∆ABC has been transformed to yield ∆A'B'C' by rotation of 180 degrees either clockwise or counterclockwise along the midpoint of AB.

The second and third figures are the same. In both figures, ∆ABC has been transformed to yield ∆A'B'C' by rotation of 180 degrees either clockwise or counterclockwise along with the origin.

In the fourth figure, ∆ABC has been transformed to yield ∆A'B'C' by rotation of 180 degrees either clockwise or counterclockwise along with the origin.

But only in the fourth figure, ∆ABC has been transformed to yield ∆A'B'C' by reflection along the x-axis.

Answer:

B.  -414,720 x⁷y⁶

Step-by-step explanation:

To find the 4th term of the expansion of (2x - 3y²)¹⁰, we can use the binomial theorem.

The binomial theorem states that for an expression of the form (a + b)ⁿ:

\(\displaystyle (a+b)^n=\binom{n}{0}a^{n-0}b^0+\binom{n}{1}a^{n-1}b^1+...+\binom{n}{r}a^{n-r}b^r+...+\binom{n}{n}a^{n-n}b^n\\\\\\\textsf{where }\displaystyle \rm \binom{n}{r} \: = \:^{n}C_{r} = \frac{n!}{r!(n-r)!}\)

For the expression (2x - 3y²)¹⁰:

Therefore, each term in the expression can be calculated using:

\(\displaystyle \boxed{\binom{n}{r}(2x)^{10-r}(-3y^2)^r}\quad \textsf{where $r = 0$ is the first term.}\)

The 4th term is when r = 3. Therefore:

\(\begin{aligned}\displaystyle &\;\;\;\;\:\binom{10}{3}(2x)^{10-3}(-3y^2)^3\\\\&=\frac{10!}{3!(10-3)!}(2x)^7(-3y^2)^3\\\\&=\frac{10!}{3!\:7!}\cdot2^7x^7(-3)^3y^6\\\\&=120\cdot 128x^7 \cdot (-27)y^6\\\\&=-414720\:x^7y^6\\\\ \end{aligned}\)

So the 4th term of the given expansion is:

\(\boxed{-414720\:x^7y^6}\)

Answer:

D

Step-by-step explanation:

Like stated in the problem the volume of a cylinder = bh where b = area of base ( which is a circle ) and h = height

The area of a circle can be calculated by using the formula: A = πr² where r = radius

The given radius is 6 cm

Thus, area of the base = π6²

6²=36

A = 36π ( note: the problem says, " Leave your answer in terms of π" therefore we do not apply π )

The given height is 10cm

If volume = area of base times height

And area of base = 36π and height = 10

Then volume = 36π * 10 which is equivalent to 360π

Hence, the answer is d

Step-by-step explanation:

As my previous answer got deleted for being wrong (in which it was right), I will answer again.

The answer is 1. Why? Just plug it into the equation. F(1) = 2(1) + 5 = 7.

This is proof that it is right, and that there are some corrupt admins on brainly.

How to get to this solution?

Well notice how we are given what f(a) is. It is 2a + 5. So plug this in for f(a).

If we do so, we get 2a + 5 = 7.

The revised Doubtful Debts Provision should be, $4,555.

Now, Using a net debtors value of $91,100 and a provision rate of 5%, use the calculation to get the adjusted Provision for Doubtful Debts (PDD):

Net Debts x Provision Rate equals Adjusted PDD.

The computation would then be:

= $91,100 x 0.05

= $4,555 is the adjusted PDD.

Because of the additional $550 in bad debt and the revised net debtors value of $91,100, the Provision for Doubtful Debts must be raised by ,

= $4,555 - $3,500

= $1,055

Answer:

Step-by-step explanation:

Answer:

its not a rational bcs 13 is non recurring decimal and not a perfect square.

Solution :

Given :

The sample mean = 21.3

Standard deviation = 3.2

The null hypothesis is : \(H_0: \mu =20\)

The alternate hypothesis : \(H_a:\mu \neq20\)

This is a two tailed test, for which a \(\text{t-test for one mean}\) with an unknown population of a standard deviation is being used.

Now the significance level, \(\alpha = 0.1\), as well as the critical value for a two tailed test is \(t_c = 1.833\)

The rejection region is \(R = \{ t:|t| > 1.833 \}\)

The t-statistic is computed as follows :

\(t=\frac{\overline x - \mu_0}{s/ \sqrt n}\)

\(t=\frac{21.3-20}{3.2/ \sqrt{10}}\)

 = 1.285

Since it is observed that \(|t| = 1.285 \leq t_c=1.833\), it is then concluded that  \(\text{the null hypothesis is not rejected.}\)

The p-value is p=0.231 and since p 0.231 ≥ 0.1, it is concluded that \(\text{the null hypothesis is not rejected.}\)

Conclusion

Thus we concluded that \(\text{null hypothesis}\) \(H_0\) is not rejected. Therefore, the population mean \(\mu\) is different than 20, at the 0.1 significance level.

The smallest to the largest side is SQ, RS, QR, the correct option is B.

A triangle is a polygon with three sides, angles, and vertices.

The triangle is classified into various types on the basis of the angle and on the basis of the equality of the length of the sides, as obtuse, acute and right-angled triangle and scalene, isosceles and equilateral triangle.

The measure of angle of the triangle is 56°, 83°, and 41°.

From the property of the triangle, the side opposite the bigger measure angle is the largest.

The measure of angle QRS is 41°, angle RQS is 56°, and angle QSR is 83°.

The smallest side will be the side opposite to QRS, i.e. SQ,
