Step-by-step explanation:
68–95–99.7 Rule : It also known as the empirical rule and it is a shorthand used to calculate the percentage of values that lie within a range around the mean in a normal distribution with the width of several standard deviation
μ = π = sample proportion
= 44 %
= 0.44
Population standard deviation proportion,
See diagram
so we got a right triangle
so for a right triangle, when we've got legs a and b and hytponuse c then
a²+b²=c²
so the legs are 90 and 90
hytponuse is distance from home to 2nd
so
90²+90²=c²
8100+8100²=c²
16200=c²
sqrt both sides
90√2=c

127.279ft
about 127ft
