randomly selected kindergarten and seventh-grade
classes.
Number of students in randomly Mean Mean absolute
selected class
deviation
Kindergarten 18, 20, 21, 19,22
20 1.2
Seventh 27, 32, 33, 33, 35
32 2.

O A. The average size of a seventh-grade class is larger and varies
more than that of a kindergarten class.
OB. The recommended number of students in a kindergarten class is
20.
O C. The average size of a seventh-grade class is larger but varies less
than that of a kindergarten class.

answer:

what is your question that you ask

step-by-step explanation:

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1

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.
