Step-by-step explanation:

Frequency distributions, count the number of times each value or range of values appears in a dataset, while percentage distributions show the proportion or percentage of times each value or range of values appears in the dataset.

Frequency distributions are useful for summarizing and describing the distribution of a variable in a data set, while percentage distributions are useful for comparing different variables or subgroups within the data set.

For example, a frequency distribution could be used to show the number of hours of sleep each participant in a study gets per night, while a percentage distribution could be used to compare the number of hours of sleep between males and females in the study.

Frequency distributions and percentage distributions provide different perspectives on the same data set and can be used together to gain a more complete understanding of the data.

Answer:

17 days

Step-by-step explanation:

Number of days in which 3 men can finish a house repair job = 10 days

Number of days in which 1 man can finish a house repair job = \(\frac{10}{3}\) days

Therefore,

Number of days in which 5 men can finish a house repair job = Number of days in which 1 man can finish a house repair job × 5

\(=\frac{10}{3}(5)=\frac{50}{3}=16.6\) ≈ 17 days

The model of for the given relationship is,

R(x) = (200 + 50x)*(10 - x), where R(x) is the revenue of one week

This graph has downward parabola, vertex at (3, 2450) intersects X axis at 10 and Y axis at 40.

Hence the Graph Y.

Given that a candlemaker prices one set of scented candles at $10 and sells an average of 200 sets each week.

If he reduces the price by $1 then the sells increases 50 more per week.

When he will reduce $ x then the sells will increase 50x per week.

Now the price of each set of scented candles = (10 - x)

and sells in a week = (200 + 50x)

So if the candlemaker's weekly revenue is R(x) then

R(x) = (200 + 50x)*(10 - x)

R(x) = 2000 + 500x - 200x - 50x²

R(x) = 2000 + 300x - 50x²

If R(x) = y, then

y = 2000 + 300x - 50x²

50(x² - 6x - 40) = - y

50{(x - 3)² - 49} = - y

50(x - 3)² - 2450 = - y

50(x - 3)² = - (y - 2450)

So, the vertex at (3, 2450) and the parabola is downwards.

when intersect X axis then y = 0

x² - 6x - 40 = 0

x² - 10x + 4x - 40 = 0

(x - 10)(x + 4) = 0

x = -4, 10

and where cuts Y axis then x = 0

y = 40

Hence the correct graph is Graph Y.

The following parts can be solved by the concept of Sets.

(a) KnF is definitely compact and closed.

(b) Fc U Kc is definitely closed, but not necessarily compact.

(c) K\F is definitely closed, but not necessarily compact.

(d) KnFc is definitely neither compact nor closed.

(a) KnF:

Since K is compact and F is closed, their intersection KnF is also closed, as the intersection of any finite number of closed sets is closed. Moreover, since K is compact, every open cover of K has a finite subcover, and thus, KnF is compact by the finite intersection property.

(b) Fc U Kc:

Fc is closed since the complement of a closed set is open, and Kc is closed since K is compact (and thus, closed) and the complement of a closed set is open. The union of two closed sets is also closed, so Fc U Kc is closed. However, Kc may not be compact, so Fc U Kc is not necessarily compact.

(c) K\F:

K\F is closed because it is the complement of the open set F. However, K\F may not be compact, as K itself may not be compact. For example, if K is the real line and F is the open interval (0,1), then K\F is not compact.

(d) KnFc:

KnFc is neither compact nor closed. To see that it is not compact, consider the sequence {x_n} in K given by x_n = (1 + 1/n, 0). This sequence converges to the point (1, 0), which is outside of K, but every term of the sequence is in K. Thus, K is not closed. On the other hand, since F is closed, Fc is open and contains K, so KnFc is not closed either.

The measure of the first angle is 200 degrees, and the measure of the second angle is 50 degrees.

To find the measure of each angle, we start by letting x represent the measure of the second angle. Since the measure of the first angle is 50 degrees more than 4 times the measure of the second angle, we can write an equation to represent this: x + 50 = 4x.

We then solve for x by subtracting x from both sides of the equation, leaving us with 50 = 3x. Dividing both sides of the equation by 3, we get x = 50. This means that the measure of the second angle is 50 degrees.

To find the measure of the first angle, we add 50 to both sides of the original equation, giving us x + 50 + 50 = 4x + 50. Simplifying, we get x + 100 = 4x. Solving for x, we get x = 200. Therefore, the measure of the first angle is 200 degrees.

Impoverished members of the South African community face numerous challenges in accessing healthcare services, as outlined in the National Health Insurance (NHI) framework. These challenges include financial barriers, limited infrastructure, geographic disparities, and inadequate healthcare resources.

Financial barriers pose a significant obstacle for impoverished individuals seeking healthcare services. Many of them cannot afford the costs associated with consultations, medications, and treatments, leading to delayed or neglected care. The NHI aims to address this by providing financial protection and ensuring equitable access to healthcare services.

Limited infrastructure in impoverished areas further hinders access to healthcare. Inadequate healthcare facilities and a shortage of medical professionals make it difficult for individuals to receive timely and comprehensive care. The NHI framework seeks to improve infrastructure by investing in healthcare facilities, expanding primary healthcare services, and increasing the number of healthcare professionals in underserved areas.

Geographic disparities also affect access to healthcare. Impoverished individuals in remote or rural areas often face challenges in reaching healthcare facilities due to transportation issues and long distances. The NHI aims to address this by promoting the establishment of healthcare facilities in underserved areas and implementing mobile clinics and telemedicine initiatives to bridge the gap.

Furthermore, inadequate healthcare resources, such as equipment, medicines, and diagnostic tools, impact the quality of care accessible to impoverished individuals. The NHI framework aims to ensure the availability and affordability of essential healthcare resources to improve health outcomes for all South Africans.

In conclusion, impoverished members of the South African community encounter multiple barriers when accessing healthcare services, including financial constraints, limited infrastructure, geographic disparities, and inadequate healthcare resources. The NHI framework aims to address these challenges and promote equitable access to quality healthcare for all citizens.

In linear regression, the variance around the regression line represents the variability of the dependent variable (response variable) that is not explained by the regression model.

It measures the dispersion of the actual data points around the predicted values from the regression line.

The variance around the regression line can vary with different values of the predictor variable. This is because the relationship between the predictor variable and the response variable may not be constant across the entire range of the predictor variable. In other words, the spread or dispersion of the data points around the regression line may change as the predictor variable changes.

By examining the residuals (the differences between the observed values and the predicted values from the regression line) and calculating their variances, you can assess the variability of the data points around the regression line. This variability is an important aspect of understanding the goodness of fit of the regression model and the accuracy of the predictions.

We have,

(a)

The formula for the future value of a CD with monthly compounding.

FV = P(1 + r/12)^(12n)

where:

P = the principal amount (initial investment)

r = the annual interest rate (as a decimal)

n = the number of years

In this case,

All invest $1200, the interest rate is 1.27% compounded monthly, and the investment is for 3 years.

Plugging these values into the formula, we get:

FV = 1200(1 + 0.0127/12)^(12*3) ≈ $1302.84

(b)

To find the amount of interest earned, we subtract the initial investment from the future value:

Interest = FV - P
