What times what gives me -48 but adds to be -32?
oee [108]

Answer:

a couple of irrational numbers: -16±4√19, approximately {1.436, -33.436}

Step-by-step explanation:

Your question can be cast as the quadratic equation

  x² +32x -48 = 0

The solutions can be found using the quadratic formula:

  x = (-32 ±√(32² -4(1)(-48)))/(2(1)) = -16±√304 = -16±4√19

_____

<em>Comment on the equation we used</em>

We notice that when p and q are roots, the equation can be written ...

  (x -p)(x -q) = 0 = x² -(p+q)x +pq

You want p+q = -32, pq = -48, so the equation is ...

  x² -(-32)x +(-48) = 0

  x² +32x -48 = 0 . . . . . . with parentheses eliminated

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.
