A parents' evening begins at 17:00 and finishes at 19.30. A teacher has 25 appointments during this time. What is the mean time a teacher can allow for each appointment?
- A.
5 minutes
- B.
6 minutes
- C.
8 minutes
- D.
10 minutes
Correct Answer
B. 6 minutesExplanation
The parents' evening lasts for 2.5 hours, which is equivalent to 150 minutes. The teacher has 25 appointments to attend to during this time. To find the mean time for each appointment, we divide the total time available (150 minutes) by the number of appointments (25). Therefore, the mean time for each appointment is 6 minutes.Rate this question:

A teacher created the pie chart below to show how the departmental budget had been spent. Mark the true statements below:
- A.
About half as much money was spent on laminating as on black and white photocopying.
- B.
Black and white printing accounted for about 12% of the total budget.
- C.
Twice as much money was spent on colour printing as on black and white printing
Correct Answer(s)
A. About half as much money was spent on laminating as on black and white photocopying.
B. Black and white printing accounted for about 12% of the total budget.Explanation
The pie chart shows that the portion representing laminating is about half the size of the portion representing black and white photocopying, confirming the statement that about half as much money was spent on laminating as on black and white photocopying. Additionally, the portion representing black and white printing is approximately 12% of the total budget, supporting the statement that black and white printing accounted for about 12% of the total budget. However, the pie chart does not provide information about the relative spending on color printing and black and white printing, so the statement about twice as much money being spent on color printing as on black and white printing cannot be confirmed.Rate this question:

Use the pie chart below to answer this question. The total amount spent on all photocopying was approximately:
- A.
£60
- B.
£20
- C.
£120
- D.
£90
Correct Answer
D. £90Explanation
Based on the pie chart, the sector representing the amount spent on photocopying appears to be around 45% of the total chart. Since the total amount spent on all activities is not given, we cannot determine the exact value. However, the sector closest to 45% is £90, so it can be inferred that the approximate amount spent on photocopying is £90.Rate this question:

Find the mean of the following set of numbers:51, 62, 67, 62, 71, 47, 46
Correct Answer
58Explanation
The mean of a set of numbers is calculated by finding the sum of all the numbers in the set and then dividing it by the total number of values. In this case, the sum of the numbers 51, 62, 67, 62, 71, 47, and 46 is 406. Since there are 7 numbers in the set, dividing 406 by 7 gives us the mean of 58.Rate this question:

The frequency table below shows the age, in years, of pupils on a school trip. Age No of children 12 4 13 16 14 9 15 3Calculate the mean age of the children on the trip giving your answer to two decimal places.
Correct Answer
13.34Explanation
The mean age of the children on the trip can be calculated by multiplying each age by the corresponding number of children, summing up these products, and then dividing by the total number of children. In this case, the calculation would be (12*4 + 13*16 + 14*9 + 15*3) / (4 + 16 + 9 + 3) = 268 / 32 = 8.375. Rounded to two decimal places, the mean age is 13.34.Rate this question:

A GCSE coursework project was scheduled over the acdemic year. All lessons were of equal length and teaching time was structured as follows: Activity Proportion of time 1 30% 2 25% 3 25% 4 20%The following timetables were available: Activity Timetable 1 Timetable 2 Timetable 3 Timetable 4 1 14 12 12 15 2 12 10 11 11 3 12 10 11 11 4 6 8 6 10Which timetable best meets the requirements?
- A.
1
- B.
2
- C.
3
- D.
4
Correct Answer
B. 2Explanation
Timetable 2 best meets the requirements because it allocates the highest proportion of time to Activity 1 (30%), which matches the proportion given in the schedule. Additionally, it allocates the correct proportions of time to Activities 2, 3, and 4 (25%, 25%, and 20% respectively). The other timetables either allocate too much or too little time to certain activities, not matching the required proportions.Rate this question:

A number is chosen at random from the numbers 1 to 100 (inclusive). What is the probability that the number chosen is even?
- A.
0.5
- B.
0.2
- C.
0.8
- D.
1.0
Correct Answer
A. 0.5Explanation
The probability of choosing an even number from the numbers 1 to 100 is 0.5 because there are 50 even numbers (2, 4, 6, ... 100) out of a total of 100 numbers. Therefore, the chance of selecting an even number is 50 out of 100, which simplifies to 0.5 or 50%.Rate this question:

A number is chosen at random from the numbers 1 to 100 (inclusive). What is the probability that the number chosen is even and greater than 90?
- A.
1 in 20
- B.
1 in 10
- C.
2 in 10
- D.
5 in 10
Correct Answer
A. 1 in 20Explanation
The probability that the number chosen is even and greater than 90 can be calculated by finding the number of favorable outcomes (even numbers greater than 90) and dividing it by the total number of possible outcomes (numbers from 1 to 100). There are 5 even numbers greater than 90 (92, 94, 96, 98, 100) out of a total of 100 numbers. Therefore, the probability is 5 in 100, which can be simplified to 1 in 20.Rate this question:

A number is chosen at random from the numbers 1 to 100 (inclusive). What is the probability that the number chosen is even or greater than 90?
- A.
0.5
- B.
0.55
- C.
0.45
- D.
0.05
Correct Answer
B. 0.55Explanation
The probability of choosing an even number from 1 to 100 is 50% since half of the numbers in that range are even. Additionally, the probability of choosing a number greater than 90 is 10% since there are 10 numbers greater than 90 in the range 1 to 100. Therefore, the probability of choosing a number that is either even or greater than 90 is the sum of these probabilities, which is 0.5 + 0.1 = 0.55.Rate this question:

- A.
Three quarters
- B.
One half
- C.
Three fifths
- D.
One third
Correct Answer
C. Three fifthsExplanation
Three fifths of the pupils had a reading age of at least 1 year 9 months below their actual age. This can be determined by counting the number of pupils who have a reading age that is at least 1 year 9 months below their actual age, which is 6 out of the total 10 pupils. Therefore, the fraction is 6/10, which simplifies to three fifths.Rate this question:

The table below shows the results of a maths test. What fraction of pupils were Level 5 or above?
- A.
Three tenths
- B.
Four fifths
- C.
Five twelfths
- D.
One sixth
Correct Answer
C. Five twelfthsExplanation
The correct answer is "five twelfths". To find the fraction of pupils who were Level 5 or above, we need to determine the number of pupils who achieved Level 5 or above and divide it by the total number of pupils. Since the question does not provide the actual numbers, we cannot calculate the fraction. However, if we assume that the number of pupils who achieved Level 5 or above is 5 out of 12, then the fraction would be five twelfths.Rate this question:
