Fill in the gap
Represent the blank with k
Solving for k...
To do this, we start by getting the coefficient of x
Coefficient of x = 22
<em />
Divide the coefficient by 2
Take the square of this result, to give k
Substitute 121 for k
The expression can be factorized as follows;
<em>Hence, the quadratic expression is </em><em></em>
convert all to a common ratio
24 1/6
30 3/6
36 2/6
(24+30+30+30+36+36)/6
186/6
the expected value is 31.
