Harlene tosses two number cubes. If a sum of 8 or 12 comes up, she gets 9 points. If not, she loses 2 points. What is the expect
Alisiya [41]
<span>It's easy enough. Solving looks like that: p(roll of 8)+p(roll of 12) =</span>\frac{5}{36} + \frac{1}{36} = \frac{1}{6} ; \frac{1}{6} *9 +\frac{5}{6}*2 = \frac{3}{2} - \frac{5}{3} = -\frac{1}{6} Hope everything is clear.

DOES THE GRAPH OF THE STRAIGHT LINE WITH SLOPE OF 4 AND Y-INTERCEPT OF -3 PASS THROUGH THE POINT (-2, 9)
lisov135 [29]

Equation of the given line will be :

  • y = 4x - 3

now, let's plug the value of x as the x - coordinate of the above point (-2 , 9) to check whether it lies on the line or not.

  • y = 4( - 2)  -  3

  • y =  - 8 - 3

  • y =  - 11

now, since value of isn't equal to the y - coordinate of the given point, so the point doesn't lies on the line.
