6 is multiplied by 2 1/3 to get to 14. 70 divided by 2 1/3 is 30. The model of the train is 30 inches long.
0.47 is the answer. Because it's in the middle of 0.43 and 0.50. I answered this on your last question =p
First set change the function f(x) to y so
that it would be

Then set y = 0

Then solve for x
X = - 3
To graph it, just plot the point (-3,0) on the x-axis
A. If the player chooses 6, 4, and 8 each time, they have 3/5 chances to win.
6+4= 10
6+8= 14
8+4= 12
These are all even so as long as they get one of these combinations they will win
b. All three combinations still work when multiplied
6*4=24
6*8=48
8*4= 32
