Step-by-step explanation:
From the question we are told to obtain the area to the of the z-score 1.39 and to the left of the z-score 1.53, this is mathematically represented as
From the z table on the question the area under the normal curve to the left corresponding to 1.53 and 1.39 is
and
So
=>
The correct answer is x^3 - 5x^2 + 16x - 80.
In order to find this, we work backwards. Start by creating true statements for each of the roots.
x = 5
x = +/-4i
Now we can solve all of these until they are statements that equal 0.
x = 5 ----> Subtract 5 from both sides
x - 5 = 0
x = +/-4i ------> Square both sides
x^2 = -16 ---> Add 16 to both sides.
x^2 + 16 = 0
Now we can use the two statements that we have and multiply them to get the polynomial.
(x - 5)(x^2 + 16)
x^3 - 5x^2 + 16x - 80
