Answer:
StartRoot 80 EndRoot
Step-by-step explanation:
|GH|² = (8 - 0)² + (1 - (-3))²
|GH|² = 64 + 16
|GH|² = 80
GH = sqrt(80)
The z-score for 5 minutes is found from:
![z=\frac{X-\mu}{\sigma} ](https://tex.z-dn.net/?f=z%3D%5Cfrac%7BX-%5Cmu%7D%7B%5Csigma%7D%0A)
![z=\frac{5-4}{0.6}=1.667](https://tex.z-dn.net/?f=z%3D%5Cfrac%7B5-4%7D%7B0.6%7D%3D1.667)
Reference to a normal distribution table shows that the cumulative probability for a z-score of 1.667 is around 0.9522.
Therefore the probability that a conversation lasts for longer than 5 minutes is:
1 - 0.9522 = 0.048 to 3 d.p.
