Let x= second number
x-1= first number
2x= 4(x-1) + 26
2x= 4x -4 + 26
2x -4x= 22
-2x= 22
(-1)(-2x)=22(-1)
2x= -22
x=-11 (second number)
-11-1= -12 (first number)

Step-by-step explanation:
The mean of the discrete probability distribution is of 1.28.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
Then, considering the given distribution, the mean is given by:
E(X) = 0(0.13) + 1(0.61) + 2(0.15) + 3(0.07) + 4(0.04) = 1.28.

Answer:
a² = 144
b² = 25
c² = 169
c = 13
Step-by-step explanation:
• a² = 12×12
= 144
• b² = 5×5
= 25
• a² + b² = c²
= 144 + 25 = 169
• c = _/169
= 13
