Find the balance in the account after the given period.

Lapatulllka [165]

Answer:

balance after 4 years = $4502

Step-by-step explanation:

Formula to get the final amount when compounded annually is,

Final amount = $\text{Principal amount}\times (1+\frac{r}{n})^{nt}$

Here, r = rate of interest

n = number of compounding per year

t = Duration of investment

From the given question,

Final amount = $4000(1+\frac{0.03}{1})^{(1\times 4)}$

= $4000(1.03)^4$

= 4502.0352

≈ $4502

Therefore, balance after 4 years = $4502

A teacher wants to know if students at Lakers High would rather have hot dogs or hamburgers at the school cookout. Which group o

mafiozo [28]

Option A.

The reasoning behind my answer is that you would be getting a large and random group of students meaning that they have many different people and not a specific group of people. Randomly choosing also gives a chance of getting all grades meaning that it wouldn't just be one specific grade of which was surveyed.

Hope this helps and have a nice day.
