La Investigadora Edith Gonzales desea estudiar la motivacion hacia la Quimica de los estudiantes de 9° grado donde ella labora, decido tomar todos los estudiantes de todos los cursos y le aplica un cuestionario cuyas respuestas son cerradas dicotomicas, los estudiantes llenas el instrumento ¿ Que tipo de estadistica esta trabajando?
¿ Que tecnica de muestro realizo, si uso alguno?
¿ Que instrumento aplico?
¿ Que tecnica de recoleccion de datos desarrollo?
¿ Universo y poblacion?

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

graph of this function as shown below:

option a, c,d are correct.

step-by-step explanation:

from the given figure, it is given that z is equidistant from the sides of the triangle rst, then from triangle tzb and triangle szb, we have

tz=sz(given)

bz=zb(common)

therefore, by rhs rule,δtzb ≅δszb

by cpctc, sz≅tz

also, from δctz and δasz,

tz=sz(given)

∠tcz=∠saz(90°)

by rhs rule, δctz ≅ δasz, therefore by cpctc, ∠ctz≅∠asz

also,from δasz and δzsb,

zs=sz(common)

∠zbs=∠saz=90°

by rhs rule, δasz ≅δzsb, therefore, by cpctc, ∠asz≅∠zsb

hence, option a, c,d are correct.

that is the sum

step-by-step explanation:

there are no other answers without knowing the variables values
