According to the general equation for conditional probability, if P(AuB')=5/9 and P(B)=1/3, what is P(A|B')?

1 answer:

3 0

$P(B)=\frac{1}{3}$
$P(B')=1-\frac{1}{3}=\frac{2}{3}$
$P(A|B')=\frac{P(A\cap B')}{P(B')}=\frac{\frac{5}{9}}{\frac{2}{3}}=\frac{5}{6}$
The correct answer choice is C.

Answer:

I think I explained the circle one before so I'll explain the left question because I wanted some points.

here,

area of circle is πr² which is given= 12 π cm²

so πr²= 12π

r= 2√3

d= 2r= 4√3

AB is diameter so AB= 4√3

What is the amount of down payment on the house that cost $65,250?

Zarrin [17]

Depends on how much percent you have to put down for the house. Like if it’s 10% then just subtract 10% from the cost of the house.

Finding a polynomial of a given degree with given zeros

galben [10]

Since f(x) is a polynomial with 3rd degree, then it will have 3 roots (zeroes)

One of them is real and the other two are complex conjugate roots

Since the real root is 4, then

x = 4

Since the complex root is (1 - i), then

The other root will be the conjugate of it (1 + i)

x = (1 - i)

x = (1 + i)

To find f(x) we will multiply the three factors of it

We can get the factors from the zeroes

$x=4$

Subtract 4 from both sides

$\begin{gathered} x-4=4-4 \\ x-4=0 \end{gathered}$

The first factor is (x - 4)

$\begin{gathered} x=1-i \\ x-(1-i)=(1-i)-(1-i) \\ x-1+i=0 \end{gathered}$

The second factor is (x - 1 + i)

The third factor is (x - 1 - i)

$f(x)=(x-4)(x-1+i)(x-1-i)$

We will multiply them to find f(x)

$\begin{gathered} (x-1+i)(x-1-i)= \\ x^2-x-ix-x+1+i+ix-i-(i^2)= \\ x^2-2x+1-(-1)= \\ x^2-2x+1+1= \\ x^2-2x+2 \end{gathered}$

Multiply it by (x - 4)

$\begin{gathered} f(x)=(x-4)(x^2-2x+2) \\ f(x)=x^3-2x^2+2x-4x^2+8x-8 \\ f(x)=x^3-6x^2+10x-8 \end{gathered}$

The answer is

$f(x)=x^3-6x^2+10x-8$
