Answer:
Step-by-step explanation:
Total number of trials =600.
Number of heads = 342.
Number of tails = 258
On tossing a coin,
and of getting a tail respectively.
then,
-8y = -4x + 16
Y = 4/8x - 2
The answer is positive since the slope is positive.
D. Because it has more balls.
These are known as simultaneous equations,,
2x + y= -3 take this as 1st equation
x-2y=-4 take this as 2 nd equation
therefore x - 2y= -2 should be multiplied by 2 inorder to cut off 2x and 2x from the first and second equations.
by multiplying we get 2x - 4y = -4
therefore 3rd equation should be substracted from 1st equation...
now, 2x -4y - 2x -y = -4-(-3)
therefore, -2x and +2x is cut.
as a result -5y= -1
therefore y = 1 /5
then let us find x
2x + y = -3
::: 2x + 1/5= -3
therefore 2x= -3-1/5
finally, x= -16/5÷2
then x= 8/5
