question 9

a) 2 x 3 = 6m^2

b) diameter = 2m and radius = 1m

c) πr^2 is the equation, so 3.14 x 1^2 = 3.14m^2

and the semi circle is half of that, 1.57m^2

d) 6 + 1.57 = 7.57m^7

question 10

30 x 70 = 2,100m^2

πr^2 so 3.14 x 15^2 = 706.5m^2

2,100 + 706.5 = 2,806.5m^2

i hope this is correct :D

When designing a study to determine this population proportion, what is the minimum number of drivers you would need to survey t
Vlada [557]

Answer: 601

Step-by-step explanation:

The formula to find the minimum sample size(n) , if the prior population proportion is unknown:

n=0.25(\dfrac{z^c}{E})^2, where E = margin of error , z^c = critical z-value for confidence level c.

Given : E  = 0.04

Z-value for 95% confidence = 1.96

So, the minimum sample size required = 0.25(\dfrac{1.96}{0.04})^2=0.25(49)^2

= 0.25\times 2401=600.25\approx601

Hence, the minimum sample size required = 601
