Answer:
12.68
Step-by-step explanation:
76 degrees /2 = 38
Half the width of 15m forms the lower side of the triangle: 7.5 m
sin(38) = 7.5/h
=12.1820
12.18+.5
12.68
The exponent indicates how many times the base is used as a factor
Answer: Our required probability is 0.067.
Step-by-step explanation:
Since we have given that
Number of days in a year = 365
Number of years = 10
So, Number of days in 10 years = 365 × 10 = 3650
Number of unprovoked shark bites in Florida = 246
so, Probability that there will be at least one unprovoked shark bite on a given day is given by

Hence, our required probability is 0.067.
