In this exercise you will need to read the information from an Amey press release about the massive Streets Ahead contract. You will then use your skills to answer the questions. You can download a worksheet or use the interactive version here.
Can you correctly answer the questions about this graph?
There are two extra questions on the worksheet which are also below.
- Draw a suitable chart to display this data.
- Write two interesting facts that the graph shows.
This is one in a large series of short videos from NCETM showing how people use maths at work. See the others here.
2. Write down the last two digits of the year. (eg 74)
3. Divide by 4 and ignore the decimal part or remainder. (eg 74 ÷ 4 = 18)
4. Add together the answers to 1 and 2 (eg 74 + 18 =92)
5. Add the number of the day of your date of birth. (eg 92 + 25 =117)
6. Add a number according to your month of birth as follows.
JAN 1 (0 for Leap Year) How do you tell if a year is a leap year?
FEB 4 (3 for Leap Year) How do you tell if a year is a leap year?
(eg 117 + 6 for Dec = 123)
For years beginning 18.. add 2
For years beginning 19.. add 0
For years beginning 20.. add 6
(eg 123 +0 = 123)
Divide your answer by 7 and work out the remainder.
(eg 123÷ 7 = 17 remainder 4)
The remainder gives the day of the week you were born on.
1 = Sunday
6 = Friday
7 = Saturday
(s0 25.12.74 was a Wednesday)
Leap years have an extra day in February, so there are 29 days in February and 366 days in a leap year. Lots of people believe that if a year is divisible by 4 it is a leap year. However there are some exceptions to this.
To work it out follow these instructions.
