A and b are rational numbers. The difference between a and b is
algol [13]

Answer:

Step-by-step explanation:

If a and b are rational and b is not zero, then a/b is also rational. Indeed, if a=m/n and b=p/q, where m,n,p, and q are integers, then a/b=mq/pn, i.e. it is also a ratio of two integers, and is therefore rational.

A waste management survey collected data about the types of materials that were recycled by three different states in
Lelechka [254]

As a percentage, the relative frequency of plastics recycling in New Mexico in 2008 compared to plastics recycled in all three states combined is approximately <u>11%</u>.

<h3>What is relative frequency?</h3>

A relative frequency measures the proportion of events that occur within a class out of the total number of observations.

When using relative frequency, the results are usually displayed in percentages, proportions, and fractions.

<h3>Data and Calculations:</h3>

Year    State                   Recycled Plastics                 Relative

                                       (thousands of tons)            Frequency

2008  New Mexico                   500                        0.111  (500/4,500)

2008  New York                     1,500                        0.333 (1,500/4,500)

2008  Texas                          2,500                        0.566 (2,500/4,500)

Total                                       4,500                        1

Thus, the relative frequency of plastics recycling in New Mexico in 2008 compared to plastics recycled in all three states combined is approximately <u>11%</u>.
