What is the domain and range of sin(x) and cos(x)?
Domain: (-inf, inf)
Range: [-1, 1]
1. How do you pronounce P(A∩B)?
2. What does it mean?
Probability of A intersect B
The probability of both A and B occurring simultaneously
Explain what mutually exclusive means when referring to probability.
Two or more events that never occur at the same time.
Find both solutions in simplified form; answers must be written as fractions:
4x2 - 8x + 1 = 0
x = (2 + sqrt(3))/2
x = (2 - sqrt(3))/2
1. How do you pronounce P(A|B)?
2. What does it mean?
Probability of A given B
The probability of A occurring, given that we know B occurred.
Name every n-sided polygon from 5 sides to 10 sides.
pentagon, hexagon, heptagon, octagon, nonagon, decagon
For a triangle: Find side b.
Angle C = 33 degrees, side c = 5
Angle B = 67 degrees, side b = ?
Angle A = ?, side a = ?
5 / sin(33) = b / sin(67)
5sin(67) / sin(33) = b
b = ~8.45
How can we use set notation to represent that P(A) and P(B) are independent?
P(A|B) = P(A)
Part 1: Name the 11 and 12-sided polygons
Part 2: To write a quadratic equation in _______ form, we can complete the square. The final form, __(write the form)__, is also known as a perfect square _________.
Hendecagon, Dodecagon
vertex
a(x-h)2 + k
trinomial
Expand this binomial: (5x + 2y)4
625x4 + 1000x3y + 600x2y2 + 160xy3 + 16y4
Assuming A and B are independent...
Part 1: What's the formula for P(A∩B)?
Part 2: What's the formula for P(A∪B)?
P(A∩B) = P(A) * P(B)
P(A∪B) = P(A) + P(B) - P(A)*P(B)
