We can solve this problem by referring to the standard
probability distribution tables for z.
We are required to find for the number of samples given the
proportion (P = 5% = 0.05) and confidence level of 95%. This would give a value
of z equivalent to:
z = 1.96
Since the problem states that it should be within the true
proportion then p = 0.5
Now we can find for the sample size using the formula:
n = (z^2) p q /E^2
where,
<span> p = 0.5</span>
q = 1 – p = 0.5
E = estimate of 5% = 0.05
Substituting:
n = (1.96^2) 0.5 * 0.5 / 0.05^2
n = 384.16

6*2=12
32-12=20
20/2=10.
Perimeter is all the way around an object. So take 6 two times and minus that from 32. Answer of that divide by 2 to get the length. Length of one side is 10 ft.
Answer:
volume is the space that fills the inside of the figure
Step-by-step explanation:
when you find the volume of the figure u have to find the space inside not surface area or the area
Answer:
C. 2 = 37
Step-by-step explanation:
<2 and 37 are vertical angles and vertical angles are equal
Angle 1 and 37 form a straight line so they add to 180
<1 + 37 = 180
<1 = 180-37 = 143
Angle 3 and 37 form a straight line so they add to 180
<3 + 37 = 180
<3= 180-37 = 143
