The probability of an event is given by the number of favorable outcomes divided by the total number of outcomes. Here the event is the alarm clock running out of power. There are 24 hours during which the power can go out. You are asleep during 8 of these. A "favorable" outcome in this case is the power going out while you are sleeping -- that is, during one of those 8 hours. This makes the probability that the power goes out while you are sleeping 8/24.

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
2x - 9y = 11
<em>x</em> = 7
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: 2(7) - 9y = 11
- Multiply: 14 - 9y = 11
- [Subtraction Property of Equality] Subtract 14 on both sides: -9y = -3
- [Division Property of Equality] Divide -9 on both sides: y = 1/3

Step-by-step explanation:
Given:
Diameter of each doughnut = 8 cm
To find: circumference of each doughnut
Solution:
Circumference refers to the boundary of a geometric figure.
A doughnut has the shape of a circle.
Let r represents the radius of the circle.
Diameter of each doughnut = 8 cm
Radius of each doughnut (r) = Diameter/2
Circumference of each doughnut 
Put 
So, circumference =
