The first two terms of a sequence are 5 and 7. Each term after the second is found by taking the average (arithmetic mean) of al
ch4aika [34]

Answer:

6

Step-by-step explanation:

We can prove that every number after the second will be a six by induction.

<em>Base case.</em> Since \frac{5 + 7}{2} = 6, so the third term is a six.

<em>Inductive hypothesis</em>. Fix the number of terms to be <em>n</em> and assume that

\frac{1}{n} \sum\limits_{i=1}^{n}t_i = 6

<em>Inductive step</em>. We will now show that \frac{1}{n+1} \sum\limits_{i=1}^{n+1}t_i = 6.

Notice that

$\begin{array}{lll}\frac{1}{n+1} \sum\limits_{i=1}^{n+1}t_i & = \frac{n}{n(n+1)} \sum\limits_{i=1}^{n+1}t_i & \\& = \frac{t_{n+1}}{n+1} + \frac{n}{n(n+1)} \sum\limits_{i=1}^{n}t_i &\\& = \frac{t_{n+1}}{n+1} + \frac{6n}{n+1} & \text{(by the IH)}\\& = \frac{6}{n+1} + \frac{6n}{n+1} & \text{by de\\finition}\\& = \frac{6(n+1)}{n+1} & \\& = 6 & \end{array} \square$

36 is what percentage of 128?<br> A. <br> B. 28 %<br> C. 28.125 %<br> D. 4,608%
skad [1K]

Answer:

C is the correct answer:

<h2>Solution for 36 is what percent of 128:</h2>

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 128 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 128, so we can write it down as 100%=128.

4. We know, that x% equals 36 of the output value, so we can write it down as x%=36.

5. Now we have two simple equations:

1) 100%=128

2) x%=36

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=128/36

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 36 is what percent of 128

100%/x%=128/36

(100/x)*x=(128/36)*x - we multiply both sides of the equation by x

100=3.55555555556*x - we divide both sides of the equation by (3.55555555556) to get x

100/3.55555555556=x

28.125=x

x=28.125

<h3>now we have:</h3>

36 is 28.125% of 128

Step-by-step explanation:

Hope it is helpful....
