12 total letters...5 vowels and 7 consonants.
probability of 1st letter being a vowel is 5/12
after replacing ...
probability of 2nd letter being a vowel is 5/12
probability of both occurring is (5/12 * 5/12) = 25/144 <===
To factor you have to do this:
s^2 + 9s = -20
+ 20 +20
s^2 + 9s + 20 = 0
now you need to numbers that multiplied give you 20
and then those same 2 numbers have to add to 9
5 x 4 = 20
5+ 4 = 9
(x + 4) (x+ 5)
that means that x= -4, and -5
Answer:
y= 3/5x + 1
Step-by-step explanation:
Slope intercept form is modeled by the equation y=mx+b.
M = slope, while B = y-intercept.
The y-intercept in this scenario equals (0, 1) or just simply 1.
The slope equals 3/5. This can be found with rise/run or y/x.
