$\frac{9}{20}$

Step-by-step explanation:

experimental probability is the probability of an event occuring when we perform an experiment.

It goes according to the results of the experiment, not the theory behind it.

Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.

Hence

P (tails) = 36/80 = 9/20

Answer:

$x=3$

$y=-4$

Step-by-step explanation:

$4x+5y=-8$ ----------- (1)

$-4x-4y=4$ -----------(2)

Adding equation (1) and (2)

$4x+5y-4x-4y=-8+4$

$y=-4$

Substitute y=-4 in equation (1) or (2)

$4x+5(-4)=-8$

$4x-20=-8\\4x=-8+20\\4x=12\\x=3$
