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:
100
Step-by-step explanation:
9-4+3=8
5*8=40
40/2=20
20*5=100
Answer:
a) 45 g
b) greater (make the graph youself on desmos or something)
c) 9/4
Step-by-step explanation:
area = integral 0 to 3 of x^2 dx = [1/3x^3] 0 to 3 = 9
mass = density * area = 5 * 9 = 45 grams
area = y*deltax = x^2*deltax
x = integral 0 to 3 of 5x^3 dx / mass = (405/4) / 45 = 9/4
Answer:
16x^4−10
Step-by-step explanation:
2+(42)(x4)−12
=2+16x4+−12
=(16x4)+(2+−12)
=16x4+−10
12x^4-10
