3   5   6   9   6   4   3   7   3   8   5

What is the mode from the above list?

Mode = most common = 3

Solve a + 17 = 25

a = 8

200

Calculate 17 x 22

10 x 22 = 220

7 x 22 = (140 + 14) = 154

17 x 22 = 374

In a classroom of 27 students, 10 of them are boys. What is the probability that a student picked at random from the class is a girl? 

27 - 10 = 17

P(Girl) = 17/27

What is the area of a square with side length 11cm?

11 x 11 = 121cm2

200

18   11   15   22   19   20   14   25   15   12

What is the range from the above data?

Range = Biggest - Smallest

= 25 - 11

= 14

Simplify 5a x 7b

5a x 7b = 35ab

Write 5,800,000 into Standard Form

5,870,000 = 5.8 x 106

The probability that a London underground train arrives early is 0.13. 

The probability that the same train arrives exactly on time 0.52.

What is the probability that this train arrives late? 

0.13 + 0.52 = 0.65

1 - 0.65 = 0.35

How many millilitres in 1.75 litres?

1 litre = 1000ml

1.7 litres = 1700ml

1.75 litres = 1750ml

8   13   2   15   5   12   6

What is the median of the above list?

Median = middle of ordered data

Ordered data = 2   5   6   8   12   13   15

Middle value = 10

Calculate 2/5 of 400

1/5 of 400 = 80

2/5 = 160

A bag contains red, blue, green and yellow marbles.

The probability that a red marble is taken at random is 0.35. 

The probability that a green marble is taken at random is 0.25. 

There an equal amount of blue and yellow marbles. 

What is the probability that a blue marble is taken at random? 

0.35 + 0.25 = 0.6

1 - 0.6 = 0.4

0.4 / 2 = 0.2

400

What is the volume of a cuboid with a base of 5cm, a length of 2cm and a height of 3.4cm? 

Volume of a Cuboid = base x length x height

= 5 x 2 x 3.4

= 10 x 3.4

= 34cm3

5   8   6   9   13   7

Calculate the mean of the above data.

Mean = Total of all Values / Number of Values

5 + 8 + 6 + 9 + 13 + 7 = 48

48 / 6 = 8

400

Solve 

7x - 3 = 2x + 12

-2x on both sides

5x - 3 = 12

+3 on both sides

5x = 15

x = 3

On the 4th January, 2011, VAT (value-added tax) increased from 17.5% to 20%. 

Calculate the VAT that would be added onto a shirt that cost £40 in 2008. 

In 2008, VAT = 17.5%

10% of £40 = £4

5% = half of 10% = £2

2.5% = half of 5% = £1

17.5% = 4 + 2 + 1 = £7

A dice was rolled 15 times and a '3' came up 4 times. 

If the same dice was rolled 180 times, how many '3's would you expect to get? 

Expected Number of 3's = P(3) x No. Rolls

No. Rolls = 180

P(3) = 4/15

4/15 x 180 = 4/15 of 180

1/15 = 12

4/15 = 48 -> You'd expect to roll 48 3's.

Angles ABC and BCE are co-interior angles on parallel lines. If angle ABC is 67o, how big is angle BCE?

Interior angles add up to 180o

Angle BCE = 180 - 67

Angle BCE = 113o

5   6   10   ?   ?   8   3

The mean of the 5 numbers is 7

The mode of the 5 numbers is 6

The range of the 7 numbers is 8

Work out the missing two numbers.

The missing numbers are 6 and 11.

Solve 

-3x + 2 = 5x - 14

+3x on both sides

2 = 8x - 14

+14 on both sides

16 = 8x

2 = x
