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:
The volume of oblique cylinders is the same volume as a right cylinder of the same radius and height. The height of cylinder must be the perpendicular height, but as long as the radius and height are the same the volume does not change, which is why the same formula can be used for both oblique and right cylinder.
For skewed and right prism, base length and height does not change, volume for both is calculated by area times height.
Answer:
±11.18
Step-by-step explanation:
the function is:
and to find the roots we need to find which values of 
makes the function result in zero:
solving for :
A square root has two solutions, one positive and one negative, so the solutions are:
±
≈ ±11.18
the roots of the quadratic equation are +11.18 and -11.18
