Answer:
P(1, π/4)
P(-1, π/4)
P(4, 5π/6)
P(-4, 5π/6)
Step-by-step explanation:
Knowing the formulas
r = √(x²+y²)
θ = Arctg (y/x)
we have
a) P(1, 1)
i)
r = √(1²+1²) = +1
r = +1
θ = Arctg (1/1) = π/4
P(1, π/4)
ii) r = √(1²+1²) = -1
r = -1
θ = Arctg (1/1) = π/4
P(-1, π/4)
b) P(2√3, -2)
i)
r = √((2√3)²+(-2)²) = +4
r = +4
θ = Arctg (-2/2√3) = 5π/6
P(4, 5π/6)
ii)
r = √((2√3)²+(-2)²) = -4
r = -4
θ = Arctg (-2/2√3) = 5π/6
P(-4, 5π/6)
Answer:
Scoring an A on a test
This is because you CHOOSE the exact answers on the test.
I think the answer might be 6 but I’m not really 100% sure
<span>The probability she failed the interview is: 1 - probability she passed the interview.
P( failed 1st interview) = 1 - 0.9 = 0.1
P(failed 2nd interview) = 1 - 0.8 = 0.2.
P(failed 3rd interview) = 1 - 0.7 = 0.3
So we have that if she didn't get the job, the probability that she failed the second interview is 0.2</span>
