<span>P(at least 1 ) = 1 - P(exactly none) = 1 - (4/5)^6 = .738
Hope this helps!!!:)</span>

Answer:

Step-by-step explanation:
Given that:
Number of seats sold is 180 with ticket price $200.
Number of seats decreases by one when the ticket price is increased by $3.
To find:
The formula for the number of seats sold (S) when the ticket price is P dollars.
Solution:
It is linear dependency of number of seats sold, S on ticket price, P.

It can be written as:

Where
is the constant of proportionality and
is a constant.
Now, putting the given values:

...... (2)
Subtracting (1) from (2):

Putting the value in (1):

Therefore the equation becomes:

I assume the question is to calculate how much work is left to complete.
we know that
the 100% of the work is equal to 1
so
To find how much work is left to complete

therefore
the work completed is equal to 
the pending work to be completed is 
the total work is equal to 
Every 7 days it will again be Monday
(150 / 7) = 21 weeks and 3 days
So, it will be a Thursday
