The correct answer for this question is "The discriminant is equal to −16, which means the equation has no real number solutions."

<span> −1 = 5x2 −2x
</span><span>5x2 −2x + 1 = 0
</span>
To get the discriminant value, use this formula
= b^2 - 4ac
= (-2)^2 - 4(5)(1)
= 4 - 20
= -16

The probability is P = 0.004, so the correct option is D.

<h3 /><h3>How to find the probability?</h3>

We want to find the probability that 4 students lie on these 30% subgroup.

We know that there are 30 students, the 30% of 30 is:

x = (30%/100%)*30 = 9

So 9 out of 30 students prefer the tests to be on Mondays.

The probability that the first randomly selected kid wants the test to be on Monday is:

p= 9/30

For the next kid, the probability is:

p'= 8/29 (because one kid was already selected).

For the next one:

p'' =7/28

For the final one:

p''' =6/27

The joint probability is the product of these 4:

P = (9/30)*(8/29)*(7/28)*(6/27) = 0.004

So the correct option is D.
