Answer:
If an event is affected by previous events then it is a dependent event, while if an event is not affected by the previous event then it is an independent event.
Since we have replaced the card that we first drew from the deck, it wont affect the event of pulling a card second time.
So, we can say that it is an example of independent event.
The discriminant is the secion inside the double parenthasees [()] below in the quadratic formulat which is
x=
![\frac{-b+ \sqrt{[(b^{2}-4ac)]} }{2a}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-b%2B%20%5Csqrt%7B%5B%28b%5E%7B2%7D-4ac%29%5D%7D%20%7D%7B2a%7D%20)
the determinant determines or tells whether the answer is real or imaginary
if it is negative, then it is imaginary, if positive, then it is real
so basically the discriminmant is

so ax^2+bx+c
a=x^2-2x-15
a=1
b=-2
c=-15
subsitute

=4-4(1)(-15)=4+60=64
the discriminant is (

) or 64
Answer:
(x+2) (x+8)
Step-by-step explanation:
12 times because you divide 60 by 5 and get 12.
