Plans were made for a rectangular garden to be planted outside of a library. The plans use a scale of 1.6 cm = 2 m. If the garde
n is 14 cm by 10 cm on the scale, find the actual dimensions. If maybe somebody could not just give me the answer, but give me the equation so I can work the rest of these questions out myself, that'd be great!

Answer:
n = 61 costumers
Step-by-step explanation:
For calculating the number of costumers he should sample we use the next equation:
Where E is the error that we are prepared to accept, in this case E = 0.15
How we don't know the value of p, we can estimate it like p = 0.5
∝ = 1-0.98 = 0.02
1-∝/2 = 0.99
n = 60.32 costumers
n ≈ 61 costumers
