The experimental probability of getting a 6 on a number cube is StartFraction 7 over 40 EndFraction. Which is true about the event’s experimental probability?
The number 6 came up a total of 40 times.
The number 6 came up 7 times out of a total of 40 trials.
The number cube was rolled a total of 47 times.
After 7 trials, the number 6 came up 40 times.

because 1.2 isnt half of 6 duh

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1

3/5

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
