Answer: 12
Step-by-step explanation:
The formula to find the sample size is given by:-
, where
is the population standard deviation,
is the z-value for the
confidence interval and E is the margin of error .
As per given , we have
Population standard deviation :
z-value for 95% confidence interval :
Margin of error : E= 3
Then, the required minimum sample :-
Hence, the required minimum sample size = 12
For this case, the first thing to do is to model the rectangular sandbox as a rectangular prism.
The volume of the prism is given by:
Where,
- <em>w: width </em>
- <em>l: length </em>
- <em>h: height </em>
Therefore, replacing values we have:
We observed that:
Therefore, the sandbox is not completely filled.
Answer:
the sandbox will hold of sand
Jodi purchase is not enough sand to fill the sandbox to the top.
Given :
Marisa wants to buy a home in Atlanta with a 30-year mortgage that has an annual interest rate of 4.9%.
The house she wants is $250,000 and she will make a $55,000 down payment and borrow the remainder.
To Find :
What is Marisa's monthly mortgage payment to the nearest dollar.
Solution :
Money remains, m = $( 250000 - 55000 ) = $195000 .
Total price after interest, T = m( 1 + rt )
T = 195000×( 1 + 0.049×1)
T = $204555
Monthly payment,
Therefore, monthly payment is $17046.25 .
Hence, this is the required solution.
