<h2>

length of rectangle = ( 4n-5 )
breadth of rectangle = ( 3n-2)
<h2>

Area and perimeter of rectangle.
<h2>
<u>solution</u><u> </u><u>:</u><u>-</u></h2>
by the question ,
We know the area of rectangle = length × breadth
Area = (4n -5) (3n-2)
now ,
perimeter = 2 ( length + breadth (
= 2 ( 4n-5 + 3n-2)
= 2 ( 7n-7)
= 14n -14

Hello! :)
Answer:
Step-by-step explanation:
PEMDAS
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
Left/Right
First, you do parenthesis.
2+3-4+(5*4)
5*4=20
2+3-4+20
Then you add/subtract from left/right.
2+3=5
5-4+20
5-4=1
1+20=21
Hope this helps!
Thanks!
Have a nice day! :)

Profit = revenue - expenses
f(x) = 4x - 1200...with x being the number of tickets sold
the domain is going to be ur x value...which is the number of tickets sold. And being that there is only 500 seats, there can be only 500 tickets sold.
So the domain is all the integers (it has to be integers because ur not gonna sell half a ticket)....all the integers from 0 to 500.
I'll get you started:
mean = np = (500)(.56) = ?
standard deviation = √npq = √(500)(.56)(.44) = ?
Note: q = 1 - p
Finish the calculations.
To find z-score:
z = (x - mean)/sd
Note: x = 250
Once you have the z-score, look in a z-table using the score to find your probability. Remember that the question is asking "at least 250" when looking at the table.
