Answer:

The sampling technique used here is Stratified random sampling.

Step-by-step explanation:

Stratified random sampling is a sampling procedure where the researcher first divided the entire population into groups, known as strata. These groups are homogeneous in nature.

Then from these strata a simple random sample of individuals are selected.

In this case the Biologist first divide the entire region of Red foxes into various groups. Then he samples 100 female foxes from each of these groups.

This is an example of stratified sampling.

Thus, the sampling technique used here is Stratified random sampling.

When 2/3 of a number is increased by 20, the sum is then halved, the result obtained is the same as 2/3 of the number, increased
lys-0071 [83]

Set up

(2/3)x + 20      This represents 2/3 of a number increased by 20.

1/2( (2/3)x + 20 )   This represents the sum is halved

then that is the same as 2/3(x) + 3

1/2( (2/3)x + 20 ) = (2/3)x + 3     Multiply the left by 1/2

(1/2 * 2/3)x + 1/2*20 = (2/3)x + 3

(1/3)x + 10 = (2/3)x + 3                 You don't have to do this but it might be nice to get rid of the fractions, so multiply both sides by 3

x + 30 = 2x + 6                            Subtract x from both sides.

x - x + 30 = 2x - x + 6                  Combine

30 = x + 6                                     Subtract 6 from both sides.

30 - 6  = x + 6 - 6                         Combine

24 = x

Check

<em><u>LHS</u></em>

(1/2)(2/3)x + 20 * 1/2

1/2 * 2/3 x + 20*1/2

1/3 x + 10

1/3 * 24 + 10

8 + 10

18

<em><u>RHS</u></em>

2/3 * 24 + 3

16 + 3

18 They do check.

Remark. Don't try to understand the problem all at once. Read it through once. You are trying to figure out only where the phrases of information begin and end. Then start writing down the results of each phrase.
