Answer:
The length of board required is 13 feet 6 inches .
Step-by-step explanation:
Board required to make one bird house = 2 feet 3 inches
= 2 x 12 + 3 = 27 inches
Number of bird houses = 6
So, the board required
= 6 x 27 = 162 inches
13.5 feet = 13 feet 6 inches
16,400 x (1 + 0.051)^20 =
16400 x (1.051)^20 =
16400 x 2.70429659 =
$44,350.46
All except the third selection are 0.
-12+12= 0
8+(-8)=0
-5+-5= -10
-20+20=0
-2,000+2,000=0
follow the the rules of integers
The numbers are not clustered around a common number. Two of the numbers are very large and one is very small.
Answer: 18
Step-by-step explanation:
The formula to find the minimum sample size is given by :_
, where 
= population standard deviation.
z*= critical z-value.
E= Margin of error.
Given : 
E= ± 8
We know that critical value corresponding to 99% confidence level = z*=2.576 [Using z-table]
Then, the required sample size would be :
[Round to next integer.]
Hence, the required minimum sample size = 18
