Answer:
c. 60.278%
Step-by-step explanation:
There is a 27.778% probability that someone owns a dog.
There is a 45% probability that someone is a male.
However, these two are not mutually exclusive. 12.5% both own a dog and are male. If we simply add 27.778% and 45%, we'll be double counting the overlap. To avoid this, we subtract 12.5%.
27.778% + 45% − 12.5% = 60.278%
Cables are forming 3 right angled triangles the pole being the shared height of them;
(height) b= 12yd
(base) a= 9yd
(hypotenuse) c= ?
Need to find the long side (hypotenuse);
a^2 + b^2 = c^2
12^2 + 9^2 = 225
Take square root of 225 = 15
Then you have;
1x 12yd = 12
3x 9 yd = 27
3x 15yd = 45
Add them up = 84yd of cable needed
5. =14
6. =17
hope this helps :)
