1. (6, -329°) (-6, 211°) (-6, -149°)
2. (5, -5π/3) (-5, 4π/3) (-5,-2π/3)
Notice: (+,+),(+,-),(-,+),(-,-).
If we consider angles beyond 360° or 2π, many other names for these points can be determined.
The polar coordinate can be written as (r, θ) = (r, θ + 2nπ) or (r, θ) = [ - r, θ + (2n + 1)π ], where n is any integer
Answer:
x=5\3,-2\3
Step-by-step explanation:
The correct answer is D hope this helps you.
The probability that the average age of a randomly selected sample of 100 students will be less than 21.8 years is 0.159
According to the given data we have the following:
mean = μ= 22
standard deviation = σ = 2
n = 100
μx = 22
σx=σ/√n=2/√100=0.2
Therefore, P( x < 21.8)=P(x-μx)/σx<(21.8-22)/0.2
=P(z<-1)
= 0.159
