Compost is used to grow plants. Ivan has a sack containing 50 litres of compost. He uses this compost to fill pots for his plants.
Ivan fills six large pots each holding 7.5 litres.
Work out how much compost is left in the sack.
[2]
Ivan uses the remaining compost to fill small pots each holding 400 ml.
Work out the maximum number of small pots Ivan can fill with the remaining compost.
[3]
Work out how much compost will then be left in the sack.

The table shows how much Amaya earns per hour.
One week Amaya works for 40 hours between Monday and Friday and then for
hours on Saturday.34
Amaya says
I will earn at least £900 for my work this week.
By rounding each value to the nearest integer, use estimation to show that Amaya may be
correct.
[5]
Give one reason why your working in part (a) shows that Amaya can be certain of earning at least £900 for her work in this week.

Kai has these four number cards.
Kai takes two of the cards at random without replacement and finds the positive difference between the two numbers.
Complete the table to show all of the possible differences.
[2]
Find the probability that Kai takes two cards with a difference that is an even number or a factor of 10.

Ryan makes a journey of 200 miles from his home to the coast. of the journey is on roads with a speed limit of 40 miles per hour. 40% of the journey is on roads with a speed limit of 50 miles per hour. The remainder of the journey takes a time of 1 hour 30 minutes.
Ryan leaves home at 08 50 and does not exceed the speed limits on the journey.
Find the earliest time that Ryan could arrive at the coast. You must show your working.

The scatter diagram shows the test scores for 20 pupils in Science and Mathematics.
Describe the type of correlation shown in the scatter diagram.
[1]
One pupil took the Science test but was then ill during the Mathematics test and had to leave early.
On the scatter diagram, circle the point that is most likely to represent this pupil.
[1]
By drawing a line of best fit, estimate the test score in Mathematics for a pupil who scored 28 in the Science test.
[2]
Explain why using the scatter diagram to estimate the test score in Mathematics for a pupil who scored 60 in Science may be unreliable.
[1]
Find the percentage of the 20 pupils who scored less than 30 marks in both Science and Mathematics.
[3]
The diagram shows an equilateral triangle and a rectangle.
The equilateral triangle has the same perimeter as the rectangle.
Find the value of a.
[4]
Charlie invests £1200 at a rate of 5% per year compound interest.
Show that the total amount of interest Charlie will have received after 2 years is £123.

A machine makes bolts that should be 30.0 mm long, correct to 1 decimal place.
Jane checks the accuracy of the machine by taking a random sample of 10 of the bolts. Here are the lengths, in mm correct to 1 decimal place, of the bolts in Jane’s sample.
29.5 29.1 30.0 30.0 30.2 30.0 30.0 30.0 30.5 30.0
The machine makes 2000 of these bolts that day.
Jane says
6 of the 10 bolts in the sample are of the correct length. That is 60%. Therefore, 1200 of the 2000 bolts will be of the correct length because that is 60%.
Give a reason why Jane’s claim may be unreliable.
[1]
In a survey, 50 people were asked whether they have a car (C) or a bicycle (B).
The Venn diagram shows some of the results.
The ratio of those that only have a car to those that only have a bicycle is 2: 1.
One of the 50 people is chosen at random.
Find the probability that they have a bicycle. You must show your working.
