Determine whether the underlined numerical value is a parameter or a statistic. explain your reasoning. upper a poll of all 2000 students in a high school found that modifying 94 % with underline of its students owned cell phones.

The numerical value is a parameter.                  

Step-by-step explanation:

We are given the following situation in the question:

A poll of all 2000 students in a high school found that Modifying 94 % with underline of its students owned cell phones.

Individual of interest:

Students in a high school found

Variable of interest:

Percentage of students owned a cell phone

Population of interest:

All 2000 high school students.

94 % with underline of its students owned cell phones.

Since this numerical value describes all of the 2000 high school student, it is describing the population of interest. Thus, the numerical value is a parameter.

4.08%

step-by-step explanation:

d) by the cross product property, ab^2 = bc multiplied by ad

step-by-step explanation:

we are given

in the given triangle abc

angle a is 90° and segment ad is perpendicular to segment bc

we can see that

triangle(abc) and triangle(abd) are similar because they have common side and same angle (90 degree)

so, triangles(abc) and abd are similar

since, they are similar

so, the ratio of their sides must be equal

we get

now, we can cross multiply

and we get

so, this could be step to prove it
