Determine which type of sampling is most appropriate. Biologists divide the regions where Red foxes are found into the​ Nearctic

, Palearctic,​ Oriental, Ethiopian, and the Australian region. They plan to follow 100 female foxes from each region to find the average​ (mean) number of their offspring.

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.

The partial factorization of x2 – 3x – 10 is modeled with algebra tiles. Which unit tiles are needed to complete the factorizati
baherus [9]
X² - 3x - 10

x² = x * x
10 can be factored:
1 x 10 ⇒⇒⇒ difference between factors = 9
2 x 5   ⇒⇒⇒ difference between factors = 3  ⇒ (The correct pair)

(x-5)(x+2) = x(x+2) - 5(x+2)
                 = x² + 2x - 5x - 10
                 = x² - 3x - 10

∴ x - 5 = 0  ⇒⇒⇒ x = 5
   x + 2 = 0  ⇒⇒⇒ x = -2

I have attached <span>algebra tiles for the given equation.</span>

Right triangle abc has one leg of length 6 cm, one leg of length 8 cm and a right angle at
Sauron [17]
Answer:
side length of the square = 10 cm

Explanation:
The attached image shows a diagram representing the scenario described in the problem.
Taking a look at this diagram, we can note that the side length of the square is equal to the hypotenuse of the right-angled triangle
Therefore, we can get the side of the square by calculating the length of the hypotenuse using Pythagorean theorem as follows:
(hypotenuse)² = (length of first leg)² + (length of second leg)²
(hypotenuse)² = (8)² + (6)²
(hypotenuse)² = 64 + 36
(hypotenuse)² = 100
hypotenuse = √100
hypotenuse = 10 cm

This means that the length of the side of the square is also 10 cm

Hope this helps :)
