For an outdoor event organizers, the expected number of people who will attend is 32700
<u>SOLUTION:</u>
Given, For an outdoor event organizers estimate that 60000 people will attend if it is not raining.
And If it is raining, event organizers estimate that 21000 people will attend.
On the day of the show, meteorologists predicted a 70% chance of rain.
We have to determine the expected number of people who will attend.
Now, number of people = 70% of rain case + 30% of other case.
Number of people = 0.7 x rain case + 0.3 x other case
Number of people = 0.7 x 21000 + 0.3 x 60000
= 2100 x 7 + 6000 x 3 = 32700.
Hence, the expected count is 32700
[a] x = 175 - 7.5p
For a, we are isolating the x variable to one side of the equation.
0.4x + 3p = 70
0.4x = - 3p + 70
x = - 7.5p + 175
[b] x = 115
For b, we are solving for x when p = 8.
x = - 7.5p + 175
x = - 7.5(8) + 175
x = 115

18 inches of ribbon
Step-by-step explanation:
that is the procedure above
Since x = 2
6(2) = 12/4
12/4 = 3
