A square lawn has a length of 8 feet and a width of 8 feet. Eight researchers each examine a randomly chosen

Goshia [24]

The best approximation to the number of seedlings that are at least 2 inches high in the entire lawn is:

D. 6,400

<h3>Total Seedlings Calculation.</h3>

To identify the total number of seedling in the entire lawn, first you must add all the seedling counted by the researchers:

Counted seedlings = 82 + 87 + 95 + 99 + 102 + 106 + 111 + 115
Counted seedlings = 697

Now, you must divide 697 in the number of regions taken by the researchers ( in this case were 8), this to obtain the average:

Average seedlings by region = $\frac{697}{8}$
Average seedlings by region = 87.125

Now, how we know, the entire lawn has a length of 8 feet and a width of 8 feet, it means 64 regions of one feet by one feet, by this reason, we multiply the average of seedlings by the whole regions in the lawn:

Number of seedlings in the lawn = 87.125 * 64
Number of seedlings in the lawn = 5576

Taking into account the average of seedlings is 5576, the best approximates of seedlings that are at least 2 inches high in the entire lawn is 6400.
