Answer:
Number cube: 1/6 Tossing tails on a coin: 1/2
A number cube is 6 sided, so the probability would be 1/6.
A coin has 2 sides, heads and tails, so tossing tails would be 1/2.
4b^-6
When u have a negative exponent, u simply take the reciprocal. So the answer is
4/b^6
Replace x in the equation with 3.5 and do the arithmetic.
y = 1.3*3.5 -0.52
y = 4.55 -0.52
y = 4.03
The predicted approximate value of y is 4.03.
So the variables has a clear casual right
