Answer:
31.5 ft
Step-by-step explanation:
Use the Pythagorean Theorem
a² + b² = c²
Plug in the knowns
a² + 23² = 39²
Subtract 23² from both sides
a² = 39² - 23²
a² = 1521 - 529
a² = 992
Take the square root of both sides
a = 31.496031496
Rounded
a = 31.5 ft
It appears that there are 30 students total (14 Male students and 16 Female Students)
We are interested in selecting a male student, and the probability of that happening is 14/30 which simplifies to 7/15
7/15 becomes 0.4667
Convert 0.4667 to a percentage and you are left with 46.67%
Rounded to the nearest whole percent, you get 47%
Answer: 47%
