Answer:
Probability of selecting one volcano in the world on which to conduct an extensive study is given by
Step-by-step explanation:
Since we have given that
Number of cinder cone volcanoes = 13
Number of shield volcanoes = 18
Number of strato volcanoes = 6
Total number of volcanoes is given by
So, Probability of getting one volcano in the world on which to conduct an extensive study is given by
Hence, Probability of selecting one volcano in the world on which to conduct an extensive study is given by

Answer:
FD = 25.94
Step-by-step explanation:
13x - 16 = 4x + 11 (Tangents drawn from an external point are equal)
13x - 4x = 11 + 16
9x = 27
x = 3
substituting x in 4x + 11,
4(3) + 11
12 + 11
23
ΔFED is a right triangle,
FD² = FE² + DE²
FD² = 12² + 23²
FD² = 144 + 529
FD² = 673
FD = 25.94
