Answer:
To avoid confusion in using the word "particle," one must state that a particle is an identifiable part of dust, a molecule, an atom, or an electron. This means that particles form these elements.
Step-by-step explanation:
For example, atoms are made up of three particles: protons, neutrons and electrons. These particles are each composed of even smaller particles known as quarks. Since quarks cannot be broken down further, they are the smallest particles known to mankind.
A class of 160 students contain 40 honor students, 60 athletes, and 80 who are neither athletes nor honor students. From the entire group a student is chosen at random. What is the probability that the student is an honor student given that he is an athlete
1/2
1/3
1/8
Answer:
⅛
Step-by-step explanation:
let x represent students who are both honor students and athletes
60+80+40-x=160
180-x=160
x=189-160=20
The probability=20/160=⅛
Answer:
The correct answer is 1/3

Answer:
x = 1,
Common Difference = -3
Step-by-step explanation:
Each number in series has the same difference, hence
(x + 1) - (2x+3) = (2x + 3) - (x + 7) Solve to find => x = 1Plug in value of x into (x+1) - (2x+3)Which solves for -3

Find the 107 the derivative of the function
Answer:
Step-by-step explanation:
Pattern
dx/dy = - sin(x)
d^2/dx^2 = -cos(x)
d3/dx^3 = sin(x)
d4/dx^4 = cos(x)
So if you divide 107 by 4 what's the remainder?
107 / 4 = 26 with a remainder of 3
So the answer is going to be the third one down or d107/dy^107 = sin(x)
