a quadratic equation has a discriminant of 12. which could be the equation? a.0 = –x2 8x 2 b.0 = 2x2 6x 3 c.0 = –x2 4x 1 d.0 = 4
Norma-Jean [14]

Answer:

Option b which is 2x^2+6x+3=0

Step-by-step explanation:

We have been given the discriminant 12

We have to choose the equation which will satisfy the given discriminant.

We will consider all the given equation one by one

First we will take option a which is -x^2+8x+2=0

Discriminant from the equation we will find by the formula

D=b^2-4ac

Here, a=-1,b=8 and c=2 on substituting the values we will get

D=8^2-4(-1)(2)=72

Hence, option a is incorrect.

Now, we will consider option b which is 2x^2+6x+3=0

Here, a=2,b=6 and c=3 on substituting the values we get

D=(6)^2-4(2)(3)=12

Hence, option b is correct

Therefore, option b is the required answer.

Vladimir [108]

Answer:

the margin of error is 0.05

Step-by-step explanation:

Margin of error = confidence interval ÷ 2

MOE = CI ÷ 2

Confidence interval CI = 0.2 - 0.1 = 0.1

MOE = CI ÷ 2 = 0.1 ÷ 2 = 0.05

the margin of error is 0.05
