By using the given table, we can see that the expected value is 20.97 AED.
<h3>
How to find the expected value?</h3>
The expected value is given by the sum between the products between the value of each outcome and the probability of said outcome.
Then, by using the table, we can write the expected value as:
Then we can see that the correct option is C, the expected value is 20.97 AED.

The final answer is x=12
So the ladder will reach 12 feet up
3x -3y = 6
or, 3(x -y)= 6
or, x-y =6/3
or, x-y = 2
or, x=2+y........eqn(i)
4x - 7y = 2
substituting the value of x from eqn(i)
or, 4(2+y) -7y = 2
or, 8 + 4y -7y = 2
or, -3y = 2-8
or, y = -6/-3
■ y=2
so in eqn(i)
x= 2+y
x= 2+2
■x = 4
Baswically find the slope of each line
slope=rise/run
for the graph we see that it rises 120 over 2 hours or 120/2 or 60mph
for the other one is where miles is rise and hours is run
2 hours to 90 miles
3 hours to 135 miles
change from 2 to 3 is 1 hour
change from 90 to 135 is 45 miles
so 45mph
60>45

It's a simple linear equation in a single variable, 'y' . Its solution is the number
that 'y' must be in order to make the equation a true statement. Here's how to
find the solution:
Write the equation: <span>15 = -y + 10
Subtract 10 from each side: 5 = -y
Multiply each side by -1 : <u>-5 = y</u>
