Yes there is a 2/3 chance. This is fun stuff!
Not enough Information. I could say 50 and it would work. I could say 68 and it would work. Any even number thats under 80 but higher than what you think her eldest son is.
Following with the extra hint that x = 82.03 m
There are 2 ways to approach the question, but although I prefer to group up x first before plugging value, having that -0.05x^2 to group up is too annoying:
Plug x = 82.03
=> Y = -0.05*(82.03^2) + 4.5*82.03 - 6.5
= -336.446045 + 369.135 - 6.5
= 26.188955 m
Please take the time and understand the answer instead of just looking at the final result.
Also I know the number is very long, but that's the question's fault. <span>¯\_(ツ)_/¯</span>
