It it is the first choice i mentioned then B is the answer.
Answer:
A=b(1/2b-1)
112ft^2
Step-by-step explanation:
-Write the equation in factored form: A= b (1/2 b -1 )
-Supposed the base of the flower bed is 16 feet. What will the area be:
b=16 feet
Formula is A=1/2(1/2b-1)
Replace the b with 16
A=1/2 (16)^2 - 16
A=1/2 (256)-16
A=256/2 - 16
A=128-16
A=112 ft^2
The area will be 112 ft^2
Answer:
The margin of error E that corresponds to a 95% confidence level is: 
Step-by-step explanation:
The propocion is 
The sample size 
95% confidence level
Level of significance = 1-level of confidence
Level of significance = 1-0.95 = 0.05
The formula for the error is:

The value for
according to the normal table
So:

We are given the following sequence:

The formula that we can use to obtain the sequence is the following:

Because when we replace the given terms we get:

For the next term:
