2 N
10 N
(4 + 4\sqrt{3})N
(6 - 4\sqrt{3})N
Correct answer is D
The vertical component = 8 \sin 300 + 6 \sin 90 + 4 \sin 180
= -4\sqrt{3} + 6 + 0
= (6 - 4\sqrt{3}) N
Calculate, correct to one decimal place, the standard deviation of the numbers: -1, 5, 0, 2 and 9.
7.2
6.6
3.6
3.2
Correct answer is C
| x | -1 | 5 | 0 | 2 | 9 | Total = 15 |
| x - \bar {x} | -4 | 2 | -3 | -1 | 6 | |
| (x - \bar{x})^{2} | 16 | 4 | 9 | 1 | 36 | 66 |
Mean = \frac{15}{5} = 3
SD = \sqrt{\frac{\sum (x - \bar {x})^{2}}{n}}
= \sqrt{\frac{66}{5}}
= \sqrt{13.2}
= 3.6
