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 <u>number of desired outcomes divided by the number of total outcomes</u>.

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 <em>probability </em>is:

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

Can someone please give me the answer I will mark u brilliant as soon as it pops up.

Answer:

  (a)  26 units

Step-by-step explanation:

The left-side vertical line extends from y = -3 to y = +3, so is 3-(-3) = 6 units long.

The bottom side horizontal line extends from x = -5 to x = 2, so is 2 -(-5) - 7 units long.

The sum of these two sides is 6 + 7 = 13 units. These two sides make up half of the perimeter, which is the total length of all four sides.

The perimeter is 2 × 13 units = 26 units.
