Answer: The answer is 80%.
Step-by-step explanation: Let us define the following events.
B = the event that the shirt is blue,
G = the event that the shirt is green
and
S = the event that the shirt is striped.
So, n(B) = 8, n(G) = 7, n(B and S) = 5, n(G and S) = 4.
n(S) = 5 + 4 = 9.
We have
Therefore, the required probability is
Thus, the answer is 80%.
<u><em>Answer:</em></u>
(c) 4.1 km
<u><em>Explanation:</em></u>
We are given that the height of the balloon is 4 km and that it is 1 km away from the station.
Setting up the diagram that describes the given scenario, we would end up with a right-angled triangle as the one shown in the attached image
<u>where:</u>
height of the balloon = 4 km represents one side of the triangle
distance between the base of the balloon and the station = 1 km represents the other side
distance between the balloon and the station is the length we want to find and it represents the hypotenuse of the triangle.
<u>To get the length of the hypotenuse, we will use the Pythagorean theorem</u>
<u>Substitute with the givens:</u>
= √17 ≈ 4.1 km
Hope this helps :)
