Work out an estimate for the number of these runners whose birthday was on that day.
(4)
| Scheme | Marks |
|---|---|
No approximation \(\dfrac{37527}{365}\) or \(\dfrac{37527}{366}\) or \(\dfrac{37527}{365.25}\) or \(\dfrac{37527}{364}\) | M2 |
| 103 | A2 |
| (4) |
Notes
M2: M1 for \(\dfrac{37527}{x}\) where \(356 \leqslant x \leqslant 370\)
A2: Accept 102 if M2 awarded
A1 for \(102.5 \leqslant \text{answer} \leqslant 103.1\)
Alternative - with approximation
| Scheme | Marks |
|---|---|
\(\dfrac{x}{y}\) or \(x \times \dfrac{1}{y}\) where \(x\) is \(35\,000 \leqslant x \leqslant 40\,000\) AND \(336 \leqslant y \leqslant 400\) | M2 |
| integer in the range 93 − 111 inclusive | A2 |
Notes
M2: M1 for \(\dfrac{x}{y}\) or \(x \times \dfrac{1}{y}\) where either the value of \(x\) or the value of \(y\) is acceptable or \(\dfrac{y}{x}\) where the values of \(x\) and \(y\) are acceptable
A2: The award of any accuracy marks is dependent on the award of M2
A1 for non-integer in the range 93 − 111
