My name is Ann [436]
<h2>Answer:</h2><h2>The expected number of people who will attend this concert = 2260</h2>

Step-by-step explanation:

The concert organizers estimate people will attend if it is not raining = 19000

If its raining people will attend = 4000

On the day of the​ concert, meteorologists predict a 90​% chance of rain.

This means 10 % chance of not raining

The expected number of people = 90% (4000) + 10% (19000)

   = 360 + 1900

  = 2260

The expected number of people who will attend this concert = 2260

kondaur [170]

The mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.

<h3>How do you calculate the mass of sodium chloride required?</h3>

Given that weigh of the person is 50 KG. The mass of the sodium chloride in one person is given below.

1 \;\rm Person = 2\times 10^2\;\rm g

The mass of sodium chloride is calculated as given below.

1.8\times 10^3 \;\rm Person = 2\times 10^2 \times 1.8\times 10^3

1.8\times 10^3 \;\rm Person = 3.6\times 10^5\;\rm g

Hence we can conclude that the mass of sodium chloride required for 1. 8 × 10^3 people is 3. 6 × 10^5 grams. Option A is the correct answer.
