ON = 8x • 8
LM = 7x + 4
NM = x - 5
OL = 3y - 6

OL is congruent & parallel to NM
LM is congruent & parallel to ON

So,
$8x \times 8 = 7x + 4$
Simplify
64x = 7x + 4

subtract 7x from both sides
57x = 4

divide 57 from both sides
$x = \frac{4}{57}$
Substitute x into equations
$8x \times 8 = 7x + 4 = 4 \frac{28}{57}$

3y - 6 = x - 5

$3y - 6 = 4 \frac{28}{57} - 5$
$3y - 6 = - \frac{28}{57}$
NM & OL = -28/57
ON & LM = 4 + (28/57)

Mathematics

answer:

probability distribution a is valid probability distribution.

step-by-step explanation:

the conditions for any probability distribution to be valid is:

(1) the probability should not be negative

2)the probability of individual should be less than 1

(3)the sum of all the probabilities must be 1.

so, first two conditions in all the three cases is true.

now, we will check for (3) condition:

the sum of all the probabilities in a is: .42+.38+.13+.07=1

therefore, a is valid probability distribution.
