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.
Answer:
i believe it is 1/3.
Step-by-step explanation:
According to the given expression, the value of b if
is -1 and + 1
Indices are expressed using exponents and bases. Some of the useful laws of indices are:

Given the expression;

This can also be expressed as:
![b^2=\frac{1}{b^{10}}\\b^2 \times b^{10} =1\\b^{2+10} =1\\b^{12}=1\\b=\pm\sqrt[12]{1}\\b=\pm1](https://tex.z-dn.net/?f=b%5E2%3D%5Cfrac%7B1%7D%7Bb%5E%7B10%7D%7D%5C%5Cb%5E2%20%5Ctimes%20b%5E%7B10%7D%20%3D1%5C%5Cb%5E%7B2%2B10%7D%20%3D1%5C%5Cb%5E%7B12%7D%3D1%5C%5Cb%3D%5Cpm%5Csqrt%5B12%5D%7B1%7D%5C%5Cb%3D%5Cpm1)
Hence the value of b from the given indices is -1 and + 1

let's recall that the graph of a function passes the "vertical line test", however, that's not guarantee that its inverse will also be a function.
A function that has an inverse expression that is also a function, must be a one-to-one function, and thus it must not only pass the vertical line test, but also the horizontal line test.
Check the picture below, the left-side shows the function looping through up and down, it passes the vertical line test, in green, but it doesn't pass the horizontal line test.
now, check the picture on the right-side, if we just restrict its domain to be squeezed to only between [0 , π], it passes the horizontal line test, and thus with that constraint in place, it's a one-to-one function and thus its inverse is also a function, with that constraint in place, or namely with that constraint, cos(x) and cos⁻¹(x) are both functions.
Answer:
Just find the number that can not be written as a simple fraction! If you attach a picture of the numbers it is easier for me to help you!
