Answer: n=6

Step-by-step explanation:

The intersecting chords theorem says that when two chords intersect each other inside a circle then the products of their segments are equal.

Therefore from the given figure, by intersecting chords theorem we have

$(n+4)\times7=5\times(n+8)\\\\\Rightarrrow7n+28=5n+40\\\\\Rightarrow7n-5n=40-28\\\\\Rightarrow2n=12\\\\\Rightarrow n=6$

Hence, the value of n = 6 units

An editor has a stack of k documents to review. The order in which the documents are reviewed is random with each ordering being

ladessa [460]

Using the probability concept, it is found that there is a $\mathbf{\frac{1}{k}}$ probability that “Relaxation Through Mathematics” is first to review.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In this problem:

There is a total of k documents to be reviewed, hence $T = k$ .
Of those documents, 1 is named “Relaxation Through Mathematics”, hence $D = 1$

The probability is:

$p = \frac{D}{T} = \frac{1}{k}$
