Answer:
3937500
Step-by-step explanation:
People watched last year = x
if ratings were up 125% x increased by x and 25% of x
25% of 10.5 million is 2625000
x increased by itself and 2625000
x*2+2625000 = 10500000
cancel out 2625000 by subtracting to both sides
10500000 - 2625000 = 7875000
x*2 = 7875000
cancel out 2 by dividing 2 on both sides
7875000/2 = 3937500
x = 3937500

Any points that are on the bolded vertical line are on the y-axis, and any points on the bolded horizontal line is on the x-axis.
P(8 or 12) = 1/6
P(not 8 or 12 = 5/6
Let the expected points fro one roll be X.

The answer is -(1/6) points.
If she studied for 2.3 she would have a total of 11.5 because if she got 5 points per hour you just have to multiply it the number of hours she spent studying. So 2.3 x 5 = 11.5! :-)
