This is an example of "a stratified sample".

<u>Answer:</u> Option B

<u>Explanation:</u>

A group-based sampling process that can be divided into subpopulations. For statistical studies, testing of each subpopulation separately may be useful if subpopulations within a total population differ, thus understood as "Stratified sampling".

One might, for instance, divide a adults sample into subgroups in terms of age, like 18 to 29, 30 to 39, 40 to 49, 50–59 etc with decided age difference as needed. A stratified sample may be more accurate than an easy sample of the similar size by random. As it offers more accuracy, a stratified sample sometimes involves a smaller sample, saving money.

Solve the system of equations by graphing where f(x)=5-2x and g(x)=(2/3)x-2. What is the value of x? 0 1 2 3 4

vfiekz [6]

Answer:

The graph is uploaded in the attachment.

The value of x is 2.625.

Step-by-step explanation:

let us plot f(x), g(x) on y-axis

so, f(x)=y and g(x)=y.

the first equation can be written as y=5-2x

the general equation of a straight is y=mx+c

( where m is the slope and c is the y-intercept )

now comparing given equation with the general equation mentioned above, the slope of first line is -2 and its y-intercept is 5

the slope of second equation i.e, y=(2/3)x-2 is 2/3 and its y-intercept is -2.

now plot the graph using above information.

(y-intercept is the the coordinate of a point where the line intersects y-axis)

(slope is the angle made by the line with the x-axis)

by seeing the graph, the value of x is 2.625.
