Asquare poster has a side length of 26 in. drawn on the poster are four identical triangles. each triangle has a base of 8 in. and a height of 8 in. children play a game in which they each wear a blindfold and throw a dart at the poster. a player whose dart lands inside a triangle wins a prize. assuming that a player's dart will always land on the poster, what is the probability of the dart landing in a triangle?

Ответ:
Divide the area of the combined areas and the total area to find the probability of landing on a triangle.
A = 1/2bh
1/2 x 8 x 8
A = 32 square inches
32 x 4
128 square inches (areas of triangles)
A = bh
26 x 26
A = 676 square inches
128/676 = 0.189
There is an approximate probability of 0.19 of hitting a triangle.
Ответ:
The answer is 0.19 (just took the test)
Step-by-step explanation:
Formula: 1/2bh
so it will be 1/2 * 8 * 8 (8 is from the base and height of the triangle)
= 32
Then you do 32 * 4 which equals 128 (this is the area of the triangles)
Next
Formula: bh
26*26 (the side lengths of the square poster)
= 676
Lastly:
128/676 (divide)
=0.189 --> which rounds to 0.19
