Answer:

Item (D)

Step-by-step explanation:

In the stratified random sample we would divide our population into homogeneous groups / strata and then  we randomly select the individuals in each group / stratum.

In general, when comparing with the simple  random sample, we realize that stratified random sampling has the advantage of increasing accuracy and decreasing  variability.

In the question, we have two strata: female students and male students. On each one of the  strata, a random sample of 25 names was made in the list.

Consider the three functions below. f(x) = Negative StartFraction 6 Over 11 EndFraction (eleven-halves) Superscript x g(x) = Sta
Setler79 [48]

Answer:

The correct option is;

The ranges of f(x) and h(x) are similar and different from the ranges of g(x)

Step-by-step explanation:

Here we have the functions given as follows;

f(x) = -6/11 (11/2)ˣ

g(x) = 6/11 (11/2)⁻ˣ

h(x) = -6/11 (11/2)⁻ˣ

from the above equations, it can be seen that f(x) and h(x) are always negative while g(x) is always positive

f(x) and h(x) are symmetric about the y axis while g(x) and h(x) are symmetric about the x axis

Also h(x) is the inverse of f(x) hence the ranges of f(x) and g(x) are similar and are different from the ranges of g(x).
