Mathematics
1 answer:
Goryan [66]3 years ago
4 0

Answer:

-1

Step-by-step explanation:

kx² + (5-x)k + 3 = 0

kx² + (5-x)k + 3 = (bx - 3)(ax + n)

kx² + (5-x)k + 3 = abx² + (bn - 3a)x -3n

thus -3n = 3 so n = -1

other root = -1

I hope this helps you :)

1 or 3, since 5 isn't included
then the other number, to be less than 5 when added,
must be
1+x<5
3+x<5
solve each
1+x<5
subtract 1
x<4
set of answers are 1,2,3

3+x<5
subtract 3
x<2
set of answer is 1
so the possible numbers are
1,2,3
that is 3 numbesr out of 9 so
probability=(total desired outcomes)/(total possible outcomes) so
disred outcomes=3
total possible=9
3/9=1/3
the probabiltiy is 1/3
