Answer: x=0.5 or 1/2
Step-by-step explanation:
2/4=1/2
Answer:

Step-by-step explanation:
we are given 8 songs
2 are <em>rock.</em><em> </em>4 are <em>reggae</em>, 2 are <em>country</em>
we want to figure out the probability of getting both reggae songs
notice that, they aren't replacing thus it's an independent probability
recall that,

P(A) represents the chance of getting our subject first time and P(B|A) represents the chance of getting the same subject second time
let's figure out P(A)
we have 2 reggae songs
and total 8 songs
therefore

let's figure out P(B|A)
since we took a reggae song before now we have only a reggae song
and total 8-1=7
therefore

Altogether

simplify multiplication:

And we are done!

Answer:
x=
80-27
Step-by-step explanation:
there is needed atleast 80 tickets and you've given 27 so you would need a minimum of 53 tickets to make the inequilaty true
Slope equals change in y divided by change in x.
m=(y2-y1)/(x2-x1)
m=(1-1)/(5--3)
m=0/8
m=0
The slope is zero.
So this is a horizontal line of the form y=1
