Answer: The employee's expected earnings is 78.5.
Step-by-step explanation:
Since we have given that
$ Probability
0 0.07
25 0.12
50 0.17
75 0.14
100 0.28
125 0.18
150 0.04
We need to find the employee's expected earnings.
As we know the formula for "Expectation":
Hence, the employee's expected earnings is 78.5.
x³ + 10x² + 25x
= x(x² + 10x + 25)
= x(x + 5)².
Let missing side be x
Using basic proportionality theorem
Answer:
x = 1
Sum the coefficients of the polynomial, that is
1 - 6 + 11 - 6 = 0
Hence x = 1 is a root and (x - 1) is a factor of the polynomial
