4(1/2x7)=12 <=> x28/2=12
x=12*2/28=24/28=12/14=6/7
5 whole and 1/6 hope it help you
Answer:
Three out of six chance
Step-by-step explanation:
There is a three out of six chance because they don’t have six numbers and three of them aren’t even so that will make it a three out of six chance. The probability of the dice landed on a one is a one out of six chance because there is only one of the number ones. I hope that’s helpful
The answer is B., valid because people were chosen randomly
This would make it a valid survey
Hope this helps!

For

the discriminant is

there are 3 basic cases of what happens for different discriminants
1. if the discriminant is less than 0, then there are no real zeroes
2. if the discriminant is 0, then it has 1 zero
3. if the discriminant is greater than 0, it has 2 zeroes
so given

a=3,b=-7,c=4
thus the discriminant is

the discriminant is 1. 1 is positive, thus the equation has 2 zeroes because the discriminant is greater than 0
the answer is the equation has two zeroes because the discriminant is greater than 0
