13. Sampling the forest To gather data on a 1200-acre pine forest in Louisiana, the U. S. Forest Service laid a
grid of 1410 equally spaced circular plots over a map
of the forest. A ground survey visited a sample of 10%
of these plots.
(a) Explain how you would use technology or Table D
to choose an SRS of 141 plots. Your description should
be clear enough for a classmate to obtain
your
results.
(b) Use your method from (a) to choose the first
3 plots.

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!

umm you say your want to . but you do know that this is the mathematics.

1.m=2

2.m=-6

3.m=3

4.m=1/2
