Activity
rima wants to learn more about the heights of the students at spring valley middle school. the school teaches students in grades 6 through 8.
each subject is taught by a different teacher, so students change classrooms every period. students don't have a class every period, but every
student has a homeroom class. consider five samples from this population, then answer the questions that follow
sample a: survey four random students in each of rima's classes.
sample b: survey two random students from each homeroom class.
sample c: survey three random girls from every third-period class.
sample d: survey every sath person in the student directory.
sample e: survey every third person in the band directory.
part a
is sample a a random sample? why or why not?

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
