Is (x + 5) a factor of f(x) = x^3 – 4x^2 + 3x + 7? Use either the remainder theorem or the factor theorem to explain your reason
stich3 [128]

ANSWER

Not a factor

EXPLANATION

The given polynomial has equation:

f(x) =  {x}^{3}  - 4 {x}^{2}  + 3x + 7

According to the remainder theorem, if (x+5) is a remainder, then f(-5)=0.

Let us substitute x=-5 into the function and evaluate to see if it will simplify to zero.

f( - 5) =  {( - 5)}^{3}  - 4 {( - 5)}^{2}  + 3( - 5)+ 7

f( - 5) =  - 125 - 100  - 15+ 7

f( - 5) =  - 233

Since the remainder is not zero, x+5 is not a factor of

f(x) =  {x}^{3}  - 4 {x}^{2}  + 3x + 7

Please help I cannot figure this one out!
ra1l [238]

Answer:

77.47%

Step-by-step explanation:

We have to use Bayes Theorem in solving this problem.

This theorem's formula is:

P(A | B) = \frac{P(A and B)}{P(B)}

Where the " | " means <u><em>"given that"</em></u>.

For our problem, using bayes theorem, we can write:

P(Student has lice | positive ) = \frac{P(StudentHasLice and Positive)}{P(Positive)}

  • P(Positive) = 0.1692 + 0.0492 = 0.2184
  • P (Student has Lice & Positive ) = 0.1692

So P(Student has lice | Positive ) = \frac{0.1692}{0.2184}=0.7747
