Answer:
The number of expected people at the concert is 8,500 people
Step-by-step explanation:
In this question, we are asked to determine the expected number of people that will attend a concert if we are given the probabilities that it will rain and it will not rain.
We proceed as follows;
The probability that it will rain is 30% or 0:3
The probability that it will not rain would be 1 -0.3 = 0.7
Now, we proceed to calculate the number of people that will attend by multiplying the probabilities by the expected number of people when it rains and when it does not rain.
Mathematically this is;
Number of expected guests = (probability of not raining * number of expected guests when it does not rain) + (probability of raining * number of expected guests when it rains)
Let’s plug values;
Number of expected guests = (0.3 * 5,000) + (0.7 * 10,000) = 1,500 + 7,000 = 8,500 people
So I was always taught to list out the multiples.
5,000:5,000 10,000 15,000 20,000 25,000 30,000 35,000 40,000
8,000:8,000 16,000 24,000 32,000 40,000
You can see more clearly that the first multiple they share is 40,000 yds
Hope that helps
Step-by-step explanation:
X1/3=2
X1=2×3
X1=5
x=5/1
area of a side = S^2 ( or s x s)
1/3 x 1/3 = 1/9
area = 1/9 square yard
Answer is C
