Answer:

The total number of ways in which the 5 people can sit is: 5!=120: 5!=120

Let us assume that person d and e are sitting together and are taken as a single entity, the number of ways in which 4 people can sit is: 4!=24: 4!=24

The number of ways in which d and e are not sitting together: 1120−24=96.

PolarNik [594]
That's what i found for you 

Each point on the graph is depicted by an ordered pair<span>, where x is always the first value and y is always the second value in the ordered pair </span>(x,y)<span>. This is because x is the </span>independent variable<span>, which means that it is the variable being changed. This makes y the </span>dependent variable<span>, which means that it is dependent on how x is being changed. We will explore this as we start to graph equations in terms of x and y. Now, even though there are two values in an order pair, they associate to only one point on the graph.</span>

Smith family spend $11208 per year to raise their child from 5 to 18 years old.

Solution:

Cost to raise the child from 5 to 18 years = $145,700

Number of years = 18 – 5 = 13

$\text{Cost per year}=\frac{\text{Total cost to raise}}{\text{Number of years} }

                      $=\frac{145700}{13}

                      = 11207.6923

                      = $11208

Cost per year = $11208

Hence Smith family spend $11208 per year to raise their child from 5 to 18 years old.
