Answer:

(2, 120° )

Step-by-step explanation:

To convert from rectangular to polar form, that is

(x, y) → (r, Θ ), use

r = \sqrt{x^2+y^2}

Θ = tan^{-1}( \frac{y}{x})

here (x, y ) = (- 1, \sqrt{3})

r = \sqrt{(-1)^2+(\sqrt{3} } )^2

  = \sqrt{1+3} = \sqrt{4} = 2

Θ = tan^{-1}(\sqrt{3}) = 60° ← related acute angle

Note (- 1, \sqrt{3}) is in the second quadrant so Θ must be in the second quadrant.

Θ = 180° - 60° = 120°

(- 1, \sqrt{3}) → (2, 120°)

Which statement best describes the use of a simulation to predict the probability that two randomly chosen people will both have
laila [671]
<span>Randomly generate an integer from 1 to 7 two times, and the probability is 1/7 ^2

This is the </span><span>statement that best describes the use of a simulation to predict the probability that two randomly chosen people will both have their birthdays on a Monday.

There are 7 days in a week, so there are 7 choices but only 1 Monday. So, 1/7 is the probability that a person's birthday falls on a Monday.

1st person asked will have 1/7 probability.
2nd person asked will also have 1/7 probability

So, (1/7)</span>² is the probability that both persons will have their birthdays on a Monday.
