Albert deposits $2785 in an account that earns 3.9% interest compounded monthly. this function models the amount in the account
Step2247 [10]

The amount for the given data is found as,\rm a = 2825(1+\frac{3.9}{12} )^{12t}.The given expression is true.

<h3>What is the amount?</h3>

The complete repayment of money at the end of the period for which it was borrowed is referred to as the amount.

The given data in the problem is;

P is the annual payment=2827

r is the rate of interest = 3.9%

n is the time period=12

The formula for the amount is found as;

\rm a = p(1+\frac{r}{n} )^{nt}

Substitute the given value;

\rm a = 2825(1+\frac{3.9}{12} )^{12t}

Hence the given expression is true.

Suppose that the annual rainfall in Ferndale, California, is known to be normally distributed, with a mean of 35.5 inches and a
erastovalidia [21]

The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.

<h3>What is the average annual rainfall?</h3>

Generally, the equation for the probability is mathematically given as

P( X < x) = p( Z < x - \mu / \sigma)

Therefore

P( X > x) = 0.021

P( X < x ) = 1 - 0.021\\\\\p( X < x) = 0.979

P( Z < x - \mu / \sigma) = 0.979

The z score for the probability of 0.979 is 2.034, according to the table of z values.

x - \mu / \sigma \\\\x= 2.034

In the given equation, replace the values of mu and sigma with their respective values, and then solve for x.

x - 35.5 / 2.5 \\x= 2.034

In conclusion, The average annual rainfall will be more than 40.6 inches in about 2.1 percent of the years.

If you deposit $5,000 in an account that earns 2% interest, compounded continuously, how much money will be in the account after
Ksivusya [100]

Answer:

$5751.37

Step-by-step explanation:

The key phrase here is "compounded continuously".  This phrase tells you that you must use the following equation:


A=Pe^{rt}

Where A is the final amount, P is the principal amount, e is the exponential constant, r is the rate in decimals and t is time.  By plugging in our known values given we obtain:


A=5000e^{0.02 \times 7}=5751.37
