Answer:

D) $11,499.63

Step-by-step explanation:

Lets use the compound interest formula provided to solve this:

A=P(1+\frac{r}{n} )^{nt}

<em>P = initial balance</em>

<em>r = interest rate (decimal)</em>

<em>n = number of times compounded annually</em>

<em>t = time</em>

<em />

First, change 4% into a decimal:

4% -> \frac{4}{100} -> 0.04

Since the interest is compounded 6 times a year, we will use 6 for n. Lets plug in the values now:

A=7,417(1+\frac{0.04}{6})^{6(11)}

A=11,499.63

Your answer is D) $11,499.63

PLEASE HELP
Kitty [74]

Answer:

542.50

Step-by-step explanation:

Given:

Least square regression equation :

y = 102.50 + 0.65x + residual

y = predicted fare

x = distance in miles

Intercept = 102.50

Slope = 0.65

Distance in miles, x = 500 miles

y = 102.50 + 0.65(500) + 115

y = 102.50 + 325 + 115

y = 427.5 + 115

y = 542.50

Which expression defines Sn for an = 5(1/3)^n?
disa [49]

If the first term is 5/3 and the common difference is 1/3. Then the infinite sum of the geometric series will be 2.5.

<h3>What is a series?</h3>

The sum of sequence terms is a series. That is, it is a list of integers connected by addition operations.

The sequence is given in the form of a variable.

\rm a_n = 5 \left (\dfrac{1}{3} \right)^{n}

The first term will be

\rm a_1 =\dfrac{5}{3}

And the common ratio will be

\rm r =\dfrac{1}{3}

Then the sum of the geometric series will be given as

\rm S_{\infty} = \dfrac{a_1}{1-r}\\\\\\S_{\infty} = \dfrac{5/3}{1-1/3}\\\\\\S_{\infty} = \dfrac{5/3}{2/3}\\\\\\S_{\infty} = \dfrac{5}{2}\\\\\\S_{\infty} = 2.5

More about the series link is given below.
