A distribution of grades in an introductory statistics course (where A = 4, B = 3, etc) is: X 0 1 2 3 4 P(X) 0.1 0.17 0.21 0.32 0.2 Part a: Find the probability that a student has passed this class with at least a C (the student's grade is at least a 2).

The probability that a student has passed this class with at least a C is 0.73

Step-by-step explanation:

A = 4 B = 3 C = 2 D = 1 E = 0

P(0) = 0.1

P(1) = 0.17

P(2) = 0.21

P(3) = 0.32

P(4) = 0.2

Probability that student passed this class with at least a C mean the score must be more than C

P(X\geq 2) = P(2) + P(3) + P(4)\\

P(X\geq 2) = 0.21 + 0.32 + 0.2\\

P(X\geq 2) = 0.73

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.

ok so the answer to your question is simple as long as you look at the different dimensions that contain the exemplary letters that combined in the right order give you words that eventually within the 5th dimension will conform and give you the correct answer to your question. hope i , stop looking at this easily, look at it with a spectral view.
