What is X when 19,695 divided by X-15,605 = 100

Zepler [3.9K]

Step-by-step explanation:

$\frac{19695}{x - 15605} = 100$

$19695 = 100(x - 15605)$

$19695 = 100x - 1560500$

$19695 + 1560500 = 100x$

$15801 95 = 100x$

$\frac{1580195}{100} = x$

$x = 15801.95$

The scores on a test for a sample of 42 statistics students are summarized in the following table. 9, 90, 18, 80, 15, 70. Find t

igomit [66]

<h3>Answer: 78.6</h3>

Work Shown:

$\begin{array}{|c|c|} \cline{1-2}\text{Number of People} & \text{Score}\\\cline{1-2}9 & 90\\\cline{1-2}18 & 80\\\cline{1-2}15 & 70\\\cline{1-2}\end{array}$

Multiply across the rows to form a third column. Example: 9*90 = 810 in the first row.

$\begin{array}{|c|c|c|} \cline{1-3}\text{Number of People} & \text{Score} & \text{Number*Score}\\\cline{1-3}9 & 90 & 810\\\cline{1-3}18 & 80 & 1440\\\cline{1-3}15 & 70 & 1050\\\cline{1-3}\end{array}$
