Question 1 of 30
1. Question
A researcher collected the following data on the number of hours students studied in a week: 12, 15, 20, 18, 25. What is the mean number of hours studied?
Correct
To find the mean of the collected data, we first need to sum all the values and then divide by the number of values. The data set provided is: 12, 15, 20, 18, 25. Step 1: Calculate the sum of the data. 12 + 15 + 20 + 18 + 25 = 90 Step 2: Count the number of values in the data set. There are 5 values. Step 3: Calculate the mean. Mean = Total Sum / Number of Values = 90 / 5 = 18 Thus, the mean of the data set is 18. The mean is a measure of central tendency that provides a single value representing the average of a data set. It is calculated by adding all the values together and dividing by the number of values. This method is particularly useful in understanding the overall trend of the data. In this case, the mean of 18 indicates that, on average, the values in the data set are around 18. This can help in making decisions based on the data, such as identifying whether certain values are above or below average, which can be critical in various fields such as business, education, and research. Understanding how to calculate and interpret the mean is essential for effective data analysis and decision-making.

Question 2 of 30
2. Question
In a bar chart displaying the number of books sold across four genres, Fiction sold 120 books, Non-Fiction sold 80 books, Science Fiction sold 60 books, and Fantasy sold 40 books. What percentage of the total books sold were in the Fiction genre?
Correct
To interpret the data from the bar chart, we first need to identify the values represented by each bar. Let’s assume the bar chart shows the number of books sold in different genres over a month. For example, if the chart indicates that Fiction sold 120 books, Non-Fiction sold 80 books, Science Fiction sold 60 books, and Fantasy sold 40 books, we can calculate the total number of books sold by adding these values together. Total books sold = Fiction + Non-Fiction + Science Fiction + Fantasy Total books sold = 120 + 80 + 60 + 40 Total books sold = 300 Next, to find the percentage of books sold in the Fiction genre, we use the formula: Percentage of Fiction = (Number of Fiction books sold / Total books sold) × 100 Percentage of Fiction = (120 / 300) × 100 Percentage of Fiction = 40% Thus, the percentage of books sold in the Fiction genre is 40%. This interpretation requires understanding how to read the bar chart, perform basic arithmetic operations, and apply the concept of percentages to derive meaningful insights from the data presented.

Question 4 of 30
4. Question
A cylindrical water tank has a radius of 3 cm and a height of 10 cm. What is the volume of the tank in cubic centimeters?
Correct
To calculate the volume of a cylinder, we use the formula: \[ V = \pi r^2 h \] where \( V \) is the volume, \( r \) is the radius, and \( h \) is the height. In this scenario, the cylinder has a radius of 3 cm and a height of 10 cm. First, we calculate the area of the base: \[ r^2 = 3^2 = 9 \, \text{cm}^2 \] Next, we multiply this area by the height: \[ V = \pi \times 9 \, \text{cm}^2 \times 10 \, \text{cm} \] \[ V = 90\pi \, \text{cm}^3 \] Using the approximation \( \pi \approx 3.14 \): \[ V \approx 90 \times 3.14 = 282.6 \, \text{cm}^3 \] Thus, the volume of the cylinder is approximately 282.6 cm³. This calculation illustrates the process of determining the volume of a three-dimensional shape, specifically a cylinder. Understanding how to apply the formula for volume is crucial, as it requires not only knowledge of the formula itself but also the ability to manipulate the values correctly. The volume of a cylinder is directly proportional to both the square of the radius and the height, meaning that even small changes in these dimensions can lead to significant differences in volume. This question tests the student’s ability to apply mathematical concepts in a practical context, reinforcing the importance of understanding geometric principles in real-world applications.

Question 6 of 30
6. Question
A customer purchases three items priced at £12.50, £8.75, and £5.99. If they have a discount coupon for 10% off the total purchase, how much will they pay after applying the discount?
Correct
To find the total cost of the items purchased, we first need to calculate the total amount spent on each item. The customer buys 3 items priced at £12.50, £8.75, and £5.99. First, we add the prices of the items: £12.50 + £8.75 + £5.99 = £27.24 Next, we need to consider that the customer has a discount coupon that offers 10% off the total purchase. To calculate the discount, we multiply the total amount by 10% (or 0.10): £27.24 * 0.10 = £2.724 Now, we subtract the discount from the total amount: £27.24 – £2.724 = £24.516 Since we typically round to two decimal places when dealing with currency, we round £24.516 to £24.52. Thus, the final amount the customer needs to pay after applying the discount is £24.52.

Question 12 of 30
12. Question
In a standard deck of 52 playing cards, what is the probability of drawing a red card?
Correct
To calculate the probability of drawing a red card from a standard deck of 52 playing cards, we first identify the total number of favorable outcomes and the total number of possible outcomes. In a standard deck, there are 26 red cards (13 hearts and 13 diamonds). The total number of cards in the deck is 52. The probability (P) of an event is calculated using the formula: P(Event) = Number of favorable outcomes / Total number of possible outcomes In this case: P(Red Card) = Number of Red Cards / Total Cards = 26 / 52 = 1/2 To express this as a decimal, we can divide 26 by 52, which equals 0.5. Therefore, the probability of drawing a red card from a standard deck of cards is 0.5 or 50%. This calculation illustrates the fundamental concept of probability, which is the measure of the likelihood that an event will occur. Understanding how to calculate probabilities is essential in various real-world applications, such as risk assessment, decision-making, and statistical analysis. It also helps in developing critical thinking skills, as one must analyze the situation, identify the total outcomes, and determine the favorable outcomes to arrive at the correct probability.

Question 14 of 30
14. Question
A customer buys 3 notebooks priced at £2.50 each and 5 pens priced at £1.20 each. If the customer pays with a £20 note, how much change will they receive?
Correct
To solve the problem, we first need to calculate the total cost of the items purchased. The customer buys 3 notebooks at £2.50 each and 5 pens at £1.20 each. Calculating the total cost of the notebooks: Total cost of notebooks = Number of notebooks × Price per notebook Total cost of notebooks = 3 × £2.50 = £7.50 Calculating the total cost of the pens: Total cost of pens = Number of pens × Price per pen Total cost of pens = 5 × £1.20 = £6.00 Now, we add the total costs of the notebooks and pens to find the overall total: Total cost = Total cost of notebooks + Total cost of pens Total cost = £7.50 + £6.00 = £13.50 The customer pays with a £20 note, so we need to calculate the change: Change = Amount paid – Total cost Change = £20.00 – £13.50 = £6.50 Thus, the correct answer is £6.50.

Question 15 of 30
15. Question
In a small survey, the following ages of participants were recorded: $12, 15, 20, 22, 30$. What is the mean age of the participants?
Correct
To find the mean of the data set, we first need to sum all the values and then divide by the number of values. The data set provided is: $12, 15, 20, 22, 30$. First, we calculate the sum: $$ 12 + 15 + 20 + 22 + 30 = 109 $$ Next, we count the number of values in the data set, which is $5$. Now, we can find the mean: $$ \text{Mean} = \frac{\text{Sum of values}}{\text{Number of values}} = \frac{109}{5} = 21.8 $$ Thus, the mean of the data set is $21.8$. In this question, we are analyzing a simple data set to find the mean, which is a fundamental concept in statistics. The mean provides a measure of central tendency, which is essential for understanding the overall trend of the data. It is important to ensure that all values are included in the sum and that the correct number of values is used in the denominator. This question tests the student’s ability to perform basic arithmetic operations and understand the concept of mean in data analysis.
Incorrect
To find the mean of the data set, we first need to sum all the values and then divide by the number of values. The data set provided is: $12, 15, 20, 22, 30$. First, we calculate the sum: $$ 12 + 15 + 20 + 22 + 30 = 109 $$ Next, we count the number of values in the data set, which is $5$. Now, we can find the mean: $$ \text{Mean} = \frac{\text{Sum of values}}{\text{Number of values}} = \frac{109}{5} = 21.8 $$ Thus, the mean of the data set is $21.8$. In this question, we are analyzing a simple data set to find the mean, which is a fundamental concept in statistics.

19. Question
A customer buys three items priced at £15.75, £22.50, and £9.99. If they have a discount coupon for 10% off the total purchase, how much will they pay after applying the discount?
Correct
To find the total cost of the items purchased, we first need to calculate the cost of each item. The first item costs £15.75, the second item costs £22.50, and the third item costs £9.99. We will add these amounts together to find the total. Total Cost = Cost of Item 1 + Cost of Item 2 + Cost of Item 3 Total Cost = £15.75 + £22.50 + £9.99 Total Cost = £48.24 Now, if the customer has a discount coupon that offers 10% off the total purchase, we need to calculate the discount amount and then subtract it from the total cost. Discount Amount = Total Cost × Discount Rate Discount Amount = £48.24 × 0.10 Discount Amount = £4.824 Now, we round the discount amount to two decimal places, which gives us £4.82. Finally, we subtract the discount from the total cost to find the final amount the customer needs to pay. Final Amount = Total Cost – Discount Amount Final Amount = £48.24 – £4.82 Final Amount = £43.42 Thus, the final amount the customer has to pay after applying the discount is £43.42.
