Answer: 151
Step-by-step explanation:
if prior population proportion is unknown , then the formula is used to find the sample size :
, where 
= Two tailed critical value for significance level of 
E = Margin of error.
Given : margin of error = 8%= .08
For 95% confidence level , two tailed critical value = 1.96
Now, the required sample size :
Hence, the size of the sample needed = 151.
It's w + 15. As it is increasing by 15, 15 is added onto it.
Answer:
A Composite figure
Step-by-step explanation:
An irregular shape that can be split into familiar shapes such as rectangle, triangles and circles is called a Composite figure.
A Composite figure may easily split into the familiar shapes such as triangles, rectangles and circles in order to find the area of these shapes.
Thus, area of such figures can be easily found out by a composite figure.
