Suppose that y varies inversely with x. Use the information to find k, and then choose the equation of variation. x = 1.2 when y

= 3.

Y = k/x where k is the constant of variation
y = 3 , x = 1.2 gives
3 = k/1.2
therefore
k = 3*1.2 = 3.6
and the required equation is

y = 3.6 / x

Which value is a solution of the equation 85= 120-w?

Ronch [10]

$85=120-w\\85-120=120-w-120\\-35=-w\\\frac{-35}{-1}=\frac{-w}{-1}\\35=w$

w = 35

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:

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