Find the variance of 1, 2, 0, -3, 5, -2, 4.
\(\frac{52}{7}\)
\(\frac{40}{7}\)
\(\frac{32}{7}\)
\(\frac{27}{7}\)
Correct answer is A
Mean, \(\bar{x} = \frac{1+2+0+(-3)+5+(-2)+4}{7} = \frac{7}{7} = 1\)
| \(x\) | \((x - \bar{x})\) | \((x - \bar{x})^{2}\) |
| 1 | 0 | 0 |
| 2 | 1 | 1 |
| 0 | -1 | 1 |
| -3 | -4 | 16 |
| 5 | 4 | 16 |
| -2 | -3 | 9 |
| 4 | 3 | 9 |
| Total (n) = 7 |
52 |
Variance = \(\frac{\sum (x - \bar{x)^{2}}{n}\)
= \(\frac{52}{7}\)

5.7\(ms^{-1}\)
6.0\(ms^{-1}\)
60.0\(ms^{-1}\)
77.5\(ms^{-1}\)
Correct answer is A
\(s = ut + \frac{1}{2}at^{2}\)
\(250 = 6u + \frac{1}{2}(12)(6^{2})\)
\(250 = 6u + 216 \implies 6u = 250 - 216 = 34\)
\(u = \frac{34}{6} \approxeq 5.7ms^{-1}\)
For what values of m is \(9y^{2} + my + 4\) a perfect square?
\(\pm {2}\)

Correct answer is B
\(T_{n} = a + (n - 1)d\)
\(380 = 9 + (n - 1)7\)
\(380 = 9 + 7n - 7 \implies 380 = 2 + 7n\)
\(7n = 380 - 2 = 378 \therefore n = \frac{378}{7} = 54\)
