Answer:
X = 1, 2.
Step-by-step explanation:
In the sample space, the most greens you can get are 2. The only other thing with green would be one green in the pair. So, the random variable for picking an outcome of green would be X = 1, 2.
Hope this helps!
First draw the first 2 pictures and then draw a subtracting line and draw the last 1 picture and solve the problem. The answer is 8.
An algebraic expression would be:
720-20x
x=the number of days
Testing out the expression:
Ex: 9 days of deleting photos
720-20(9)
720-180
=540 photos left
Hope this helps!

K guys u rly need to learn this stuff instead of relying on google for answers, it's not hard, I promise.
Ratio is 5:4
Which is Length: Width.
We're told the Length (in Inches) is 60.
So ratio = 60: ?
A Ratio is just a simplified version of the actual numbers, k?
So The length 'scale', if you like, will be 60/5. =12.
That means one 'unit' of Ratio stuff = 12.
So then you work out the Width, by doing the Ratio number [4] x The Ratio 'scale' [12].
4 x 12 = 48! It's 48 Inches.
