Answer:
<h2>
64 cm²</h2>
Step-by-step explanation:
given:
the scale from a square park to a drawing of the park is 5 m to 1 cm
the actual park has an area of 1,600 m²
find:
what is the area of the drawing of the park
solution:
drawing scale is 5m : 1cm
<u>1,600 m² </u> = <u> 5² m² </u>
x 1² cm²
cross multiply:
5² m² x = 1600 m² (1 cm²)
x =<u> 1600 m² </u>
5² m²
x = 64 cm²
therefore, the area of a square park in the drawing is 64 cm²

Answer: n= 14
Step-by-step explanation:
The formula to find the sample size :_

, where p= Prior estimate of population proportion.
z* = Critical value.
E= Margin of error.
Given : Prior estimate of population proportion : p= 0.025
We know that , the critical value for 90% confidence interval :

E= 7.0%=0.070
Then , the required minimum sample size :

i.e. n= 14
Hence, the sample size needed : n= 14
