-We determine the z-value corresponding to the 95% confidence level:
-The margin of error is the degree of error from the real value and is calculated as follows:
Hence, the margin of error is
Ok so what is do is
the bottom half is the radius
the top half is a little bit m ore tricky
we can do
18=base
15=sides
makes an equilateral traignel
split it up into
base 18/2=9
hypotonuse 15
height=?
9^2+x^2=15^2
81+x^2=225
x^2=144
x=12
height=12
add
radis=15
height=12
15+12=27
27 cm
Answer:
<h2>i. 18 days</h2><h2>
ii. part of work</h2><h2>
iii. part of work</h2><h2 />
