Answers
9. The stamp duty payable on a property with a purchase price of K45,000 is K1,350.
10. The stamp duty payable on a property with a purchase price of K150,000 is K7,500.
To calculate the stamp duty payable on properties with a purchase price of K45,000 and K150,000, we need to apply the corresponding rates of stamp duty based on the given information.
Given:
Value of Property:
Up to K35,000: Stamp Duty Rate - 2%
K35,000 to K70,000: Stamp Duty Rate - 3%
K70,000 to K140,000: Stamp Duty Rate - 4%
Over K140,000: Stamp Duty Rate - 5%
9. Calculate the stamp duty payable on properties whose purchase price is K45,000:
Since the purchase price of K45,000 falls within the range of K35,000 to K70,000, the stamp duty rate applicable is 3%.
Stamp Duty Payable = Purchase Price * Stamp Duty Rate
= K45,000 * 3%
= K45,000 * 0.03
= K1,350
Therefore, the stamp duty payable on a property with a purchase price of K45,000 is K1,350.
10. Calculate the stamp duty payable on properties whose purchase price is K150,000:
Since the purchase price of K150,000 is above K140,000, the stamp duty rate applicable is 5%.
Stamp Duty Payable = Purchase Price * Stamp Duty Rate
= K150,000 * 5%
= K150,000 * 0.05
= K7,500
Therefore, the stamp duty payable on a property with a purchase price of K150,000 is K7,500.

When solving inequality
If in the numerator i had a imaginary number when factoring what should i do???
Answers
Answer:
we need to factorise if imaginary number is in the denominator. no action is required if its in the numerator.
you can factorise an imaginary number by multiplying both the numerator and denominator by the conjuncate of the complex number
for instance,
we've given a complex number as follows
\( \frac{x}{3x + 4i} \)
factorising
\( \frac{x}{3x + 4i} \times \frac{3x - 4i}{3x - 4i} \)
as 3x -4i is the conjugate of 3x + 4i
and 4i is the imaginary number
\( \frac{ x(3x - 4i)}{9x {}^{2} - 4 {i}^{2} }\)
and since i² = -1
\(\frac{ x(3x - 4i)}{9x {}^{2} + 4}\)
hence factorised
l(x) = 2(2x + 1)3(2 – 2x)3

What is the measure of 23, in degrees, in the figure shown? 30° 137° 3
Answers
Answer:
73°
Step-by-step explanation:
This equation uses two supplementary angles. Supplementary angles are two angles that add up to 180 degrees.
The triangle has two angles implied, 30 degrees and (180-137) degrees.
(180 - 137) = 43 degrees
Now that we have two angles inside the triangle, we subtract them from 180 to find the last angle.
180 - 43 - 30 = 107
The angle with a measure of 107 degrees and angle 3 are supplementary
180 - 107 = 73 degrees
Answer:73.4° Fahrenheit.

The National Assessment of Educational Progress (NAEP) includes a mathematics test for eighth‑grade students. Scores on the test range from 0 to 500. Demonstrating the ability to use the mean to solve a problem is an example of the skills and knowledge associated with performance at the Basic level. An example of the knowledge and skills associated with the Proficient level is being able to read and interpret a stem‑and‑leaf plot.
In 2019, 147,400 eighth‑graders were in the NAEP sample for the mathematics test. The mean mathematics score was Xbar=282. We want to estimate the mean score in the population of all eighth‑graders. Consider the NAEP sample as an SRS from a Normal population with standard deviation =40.
If we take many samples, the sample mean Xbar varies from sample to sample according to a Normal distribution with mean equal to the unknown mean score in the population. What is the standard deviation of this sampling distribution?
Give your answer to four decimal places.
Answers
The standard deviation of the sampling distribution is approximately 0.3292.
What is central limit theorem?The behaviour of the sampling distribution of the mean is described by the central limit theorem, a key conclusion in statistics. It asserts that regardless of how the population distribution is shaped, if a random sample of size n is taken from a population with mean and standard deviation, the distribution of sample means will tend towards a normal distribution as n increases.
Because it enables us to utilise the normal distribution to draw conclusions about the population mean based on sample means, the central limit theorem has significant practical ramifications. Additionally, it offers a foundation for confidence interval estimation and statistical hypothesis testing.
The standard deviation is given by the formula:
SD = σ/√(n)
Now, substituting the value of σ = 40, n = 147,400 we have:
SD = σ/√(n) = 40/√(147400) ≈ 0.3292
Hence, the standard deviation of the sampling distribution is approximately 0.3292.

sum the 3 angles and equate to 180
31 + x + 4 + 3x + 9 = 180
4x + 44 = 180 ( subtract 44 from both sides )
4x = 136 ( divide both sides by 4 )
x = 34

1. Global warming creates local problems. Projections forecast that even a moderate air temperature increase of only 1.8 °F could cause brook trout distributions to decrease dramatically. For example, such a temperature increase would take Washburn county's 19 ponds that support brook trout down to 10 ponds. What would be the percent decrease in the number of ponds that support brook trout?
Answers
The percent decrease in the number of ponds that support brook trout would be approximately 47.37%.
To calculate the percent decrease in the number of ponds that support brook trout, we need to determine the difference between the initial number of ponds and the final number of ponds, and then express that difference as a percentage of the initial number of ponds.
Initial number of ponds: 19
Final number of ponds: 10
To calculate the percent decrease, we can use the following formula:
Percent Decrease = (Difference / Initial Value) * 100
Let's apply this formula to the given data:
Difference = Initial number of ponds - Final number of ponds
Difference = 19 - 10
Difference = 9
Percent Decrease = (9 / 19) * 100
Now, let's calculate the percent decrease:
Percent Decrease = (9 / 19) * 100
Percent Decrease ≈ 47.37%

From the top of a 189-ft lighthouse, the angle of depression to a ship in the ocean is 27°. How far is the ship from the base of the lighthouse?
Answers
the ship is approximately 398.4 feet from the base of the lighthouse.
We can see that the angle of depression from the top of the lighthouse to the ship is 27°. This means that the angle between the horizontal and the line from the top of the lighthouse to the ship is also 27°.
We want to find the distance from the ship to the base of the lighthouse, which we can call x. We can use the tangent function to relate the angle and the distances:
tan(27°) = opposite / adjacent
n this case, the opposite side is the height of the lighthouse, 189 ft, and the adjacent side is x, the distance from the ship to the base of the lighthouse. So we can solve for x:tan(27°) = 189 / x
x = 189 / tan(27°)
x ≈ 398.4 ft

A particular brand of tires claims that its deluxe tire averages at least 50,000 miles before it needs to be replaced. From past studies of this tire, the standard deviation is known to be 8,000. A survey of owners of that tire design is conducted. Of the 28 tires surveyed, the mean lifespan was 46,300 miles with a standard deviation of 9,800 miles. Using alpha = 0.05, is the data highly consistent with the claim? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
Answers
Answer:
\(z=\frac{46300-50000}{\frac{9800}{\sqrt{28}}}=-1.998\)
Now we can calculate the p value using the alternative hypothesis with this probability:
\(p_v =P(z<-1.998)=0.0229\)
The p value for this case is significantly lower than the value of \(\alpha=0.05\) so then we can reject the null hypothesis at this signficance level and we have enough evidence to conclude that the true mean for the deluxe tire is less than 50000 and the claim is not correct.
Step-by-step explanation:
Information given
\(\bar X=46300\) represent the sample mean for the lifespans
\(\sigma=9800\) represent the population standard deviation
\(n=28\) sample size
\(\mu_o =50000\) represent the value to verify
\(\alpha=0.05\) represent the significance level
z would represent the statistic
\(p_v\) represent the p value
System of hypothesis
The idea for this case is verify if the deluxe tire averages at least 50,000, so then the system of hypothesis are:
Null hypothesis:\(\mu \geq 50000\)
Alternative hypothesis:\(\mu < 50000\)
We know the population deviation so then the correct test stattistic would be:
\(z=\frac{\bar X-\mu_o}{\frac{\sigma}{\sqrt{n}}}\) (1)
Replacing the info given we got:
\(z=\frac{46300-50000}{\frac{9800}{\sqrt{28}}}=-1.998\)
Now we can calculate the p value using the alternative hypothesis with this probability:
\(p_v =P(z<-1.998)=0.0229\)
The p value for this case is significantly lower than the value of \(\alpha=0.05\) so then we can reject the null hypothesis at this signficance level and we have enough evidence to conclude that the true mean for the deluxe tire is less than 50000 and the claim is not correct.

Find the indicated confidence interval. Assume the standard error comes from a bootstrap distribution that is approximately normally distributed.
Answers
The 99% confidence interval for the population proportion p is (0.776, 0.824).
To find the 99% confidence interval for a proportion, we can use the formula:
CI = p^ ± z*(SE)
where p^ is the sample proportion, SE is the standard error, and z is the critical value from the standard normal distribution corresponding to the level of confidence.
For a 99% confidence interval, the critical value z is 2.576.
Substituting the given values into the formula, we have:
CI = 0.80 ± 2.576*(0.03/√200)
Simplifying this expression, we have:
CI = 0.80 ± 0.024
This means that we are 99% confident that the true population proportion falls between 0.776 and 0.824. We can interpret this interval as a range of plausible values for the population proportion, based on the sample data.
