There actually is a mean, you take the two middle numbers, add them together then divide by two.

mean=242.83
median=265

Find the series shown.
solmaris [256]

Answer:

C 11+13+15+17+...

Step-by-step explanation:

Consider the series

\sum\limits_{n=3}^{\infty}(2n+5)

The nth term of series is a_n=2n+5

The bottom index tells you that n starts changing from 3, so

a_3=2\cdor 3+5=11\\ \\a_4=2\cdot 4+5=13\\ \\a_5=2\cdot 5+5=15\\ \\a_6=2\cdot 6+5=17\\ \\...

Thus, the sum of all terms is

11+13+15+17+...

gtnhenbr [62]

Answer:

Domain\ =\ \{x: 9,10,11....16\}

<em></em>Range\ =\ \{y:290, 315,340.....465\}<em></em>

Step-by-step explanation:

Given

y = 25x + 65

Required

Determine the range and domain when x = 9 to 16

The domain is the set of

Domain\ =\ \{x: 9,10,11....16\}

Solving for the range;

<em>When x = 9</em>

<em></em>y = 25 * 9 + 65<em></em>

<em></em>y = 225 + 65<em></em>

<em></em>y = 290<em></em>

<em></em>

<em>When x = 10</em>

<em></em>y = 25 * 10 + 65<em></em>

<em></em>y = 250 + 65<em></em>

<em></em>y = 315<em></em>

<em></em>

<em>When x = 11</em>

<em></em>y = 25 * 11 + 65<em></em>

<em></em>y = 275 + 65<em></em>

<em></em>y = 340<em></em>

<em></em>

<em>You continue till you get to x = 16</em>

<em>---</em>

<em>--</em>

<em>-</em>

<em>When x = 16</em>

<em></em>y = 25 * 16 + 65<em></em>

<em></em>y = 400 + 65<em></em>

<em></em>y = 465<em></em>

<em></em>

<em>Hence; the range is</em>

<em></em>Range\ =\ \{y:290, 315,340.....465\}<em></em>
