snow_tiger [21]

Answer:

Step-by-step explanation:

Using the area model and standard algorithm, we have:

                332   (tenths)

         <u> ×       21  </u>

                332

        <u>      664     </u>

        <u>      6972  </u> tenths = 697.2

<u />

              30      +      3      tenths

     1       300           32         332

    20     600           64         664

33.2 × 21 =<u>    30    </u> × <u>    1     </u>  =  <u>      30     </u>

Liula [17]

The best prediction of the total number of tagged salmon in a sample of 2000 is 100.

<h3><u>Predictions</u></h3>

To determine what is the best prediction of the total number of tagged salmon in a sample of 2000, the following calculation must be performed:

  • 800 = 40
  • 2000 = X
  • 2000 x 40 / 800 = X
  • 80000 / 800 = X
  • 100 = X

Therefore, the best prediction of the total number of tagged salmon in a sample of 2000 is 100.
