A. in terms of the number of marked elk, what is the relative frequency of male elk, female elk, adult elk, and baby elk? write
mash [69]

The relative frequency of the marked elks are:

  • Male Elk  = 7/30
  • Female Elk = 4/15
  • Adult Elk= 173/450
  • Baby Elk = 26/22

<h3>How to determine the relative frequency?</h3>

From the complete question, we have:

  • Male = 105
  • Female = 120
  • Adult =  173
  • Baby = 52
  • Total = 450

The relative frequency of each is then calculated as:

Male Elk = 105/450

Male Elk  = 7/30

Female Elk = 120/450

Female Elk = 4/15

Adult Elk= 173/450

Baby Elk = 52/450

Baby Elk = 26/22

<h3>The number of Elks in the park</h3>

Using the data in (a), we can conclude that:

There are 105 male, 120 female, 173 adult, and 26 baby in the park

What is the total amount of paper, glass, and plastic waste not recovered
xenn [34]

Answer:

63,630,000 tons not recovered

Step-by-step explanation:

Paper generated = 71,310,000 tons

Paper recovered = 44,570,000 tons

Glass generated = 11,530,000 tons

Glass recovered = 3,130,000 tons

Plastics generated = 31,040,000 tons

Plastics recovered = 2,550,000 tons

Total generated = 113,880,000 tons

Total recovered = 50,250,000 tons

113,880,000 - 50,250,000 = 63,630,000 tons not recovered
