Answer:
The equation which can be used to find the value of numbers
(x) + (x + 1) + (x + 2) = - 21
Step-by-step explanation:
Let the first no. is = x
Second number = x + 1
Third number = x + 2
The sum of three consecutive numbers = x + x + 1 + x + 2
Given that Three consecutive integers have a sum of –21.
Therefore
(x) + (x + 1) + (x + 2) = - 21
This is the equation which can be used to find the value of numbers.

2u+7u=9u
9u=81
Divide both sides
U=9
Expected value is $20.20
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
