Answer:
The probability of picking a letter that is not a vowel is 3/4.
Step-by-step explanation:
There are 2 vowels and the rest are not.
There are 6 out 8 titles that are not vowel.
6/8 = 3/4
1/6
A and E are vowels so you minus it by 8, which makes it 6.
x²=5-x
x²+x-5=0
1x²+1x²-5=0
[ax²+bx²+c=0]
∆=b²-4ac
∆=1²-4(-5)(1)=1+20=21
x=(-b±√∆)/2a
x=(-1±√21)/2
meaning:
x=(-1+√21)/2 or x=(-1-√21)/2
i thinks its B thats what i put but im not sure , i havent got the paper back yet
