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.

An unbiased cubic die has numbers 1 to 6 inscribed on each side. on average, how many rolls will you need in order to get a 6?

GaryK [48]

(5/6)^x < 0.5
x = ceiling( log(0.5) / log(5/6) )
<span>x = 4

Here I worked it out, hopefully this helps :)

A washer and a dryer cost $614 combined. The washer costs $ 86 less than the dryer. What is the cost of the dryer?

Vikki [24]

Answer:

$350

Step-by-step explanation:

Let's say that the dryer has price x. If this is the case, then the washer must have price x-86. We know that the two added together must be 614 dollars, so you can set up the following equation:

x+x-86=614

2x=700

x=350

Hope this helps!
