aleksandr82 [10.1K]

Answer:

Probability both are hopelessly romantic = 0.0169

Probability at least one is hopelessly romantic = 0.2431

Step-by-step explanation:

We are given that about 1313​% of the population of a large country is hopelessly romantic.

Also, given two people are randomly​ selected.

Firstly, Let <em>Probability that the population of a large country is hopelessly romantic = P(R) = 0.13 </em>

(a) Probability both are hopelessly romantic is given by = Probability that first person is hopelessly romantic \times Probability that second person is hopelessly romantic

                         = P(R) \times P(R)

                         = 0.13 \times 0.13 = <u>0.0169</u>

(b) Now, Probability that the population of a large country is not hopelessly romantic = P(R') = 1 - P(R) = 1 - 0.13 = 0.87.

So, Probability at least one is hopelessly romantic is given by = 1 - Probability that none of them is hopelessly romantic

                         = 1 - (P(R') \times P(R'))

                         = 1 - (0.87 \times 0.87)

                         = 1 - 0.7569 = <u>0.2431</u>

Jasmine wants to use her savings of $1,128 to buy video games and music cds. The total price of the music cd she bought was $72.
Firlakuza [10]
24 video games.

First you subtract $72 from $1,128 then you divide $43 from $1,056 and you get 24.5581395
So the most video games jasmine can buy is 24.

Will mark correct answer branliest!!!
WITCHER [35]

Answer: A = 4    P = π     PS = -π/2

<u>Step-by-step explanation:</u>

y = A sin(Bx - C) + D      where

  • A is the amplitude
  • Period = 2π/B
  • Phase Shift = C/B
  • D is the vertical shift

Given:  y = -4 sin(2x + π) - 3

  • A (amplitude) = 4      <em>the negative sign is a reflection, not amplitude</em>
  • B = 2
  • C = -π
  • D = -3

Amplitude = 4

\text{Period}=\dfrac{2\pi}{B}\quad =\quad \dfrac{2\pi}{2}\quad =\quad \pi

\text{Phase Shift}=\dfrac{C}{B}\quad =\quad \dfrac{-\pi}{2}\quad =\quad -\dfrac{\pi}{2}
