Assume that the business makes a profit with probability 0.8 in the first year. For each year thereafter, the business makes a p

Ivenika [448]

Answer:

The probability that the business makes a profit in exactly two of its first three years is 0.628.

Step-by-step explanation:

Given : Assume that the business makes a profit with probability 0.8 in the first year. For each year thereafter, the business makes a profit with probability 0.9 if it made a profit in the previous year, and with probability 0.2 if it did not make a profit in the previous year.

To find : What is the probability that the business makes a profit in exactly two of its first three years?

Solution :

Let X be the event that the business makes profit.

Y be the event that the business doesn't .

The business makes a profit with probability 0.8 in the first year.

For each year thereafter, the business makes a profit with probability 0.9.

It did not make a profit in the previous year is 0.2.

According to question,

The business makes a profit in exactly two of its first three years which is given by, XXY, XYX, YXX

So,

$P(XXY)=0.8\times 0.9\times (1-0.2)$

$P(XXY)=0.8\times 0.9\times 0.8$

$P(XXY)=0.576$

$P(XYX)=0.8\times (1-0.9)\times 0.2$

$P(XYX)=0.8\times 0.1\times 0.2$

$P(XYX)=0.016$

$P(YXX)=(1-0.8)\times 0.9\times 0.2$

$P(YXX)=0.2\times 0.9\times 0.2$

$P(YXX)=0.036$

The probability that the business makes a profit in exactly two of its first three years is given by,

P= P(XXY)+P(XYX)+P(YXX)

P= 0.576+0.016+0.036

P= 0.628

Therefore, The probability that the business makes a profit in exactly two of its first three years is 0.628.

= 0.272

Solve <br> f(x)=4x5−8x4+8x2−4x

Goryan [66]

Given:

The function is:

$f(x)=4x^5-8x^4+8x^2-4x$

To find:

The roots of the given equation.

Solution:

We have,

$f(x)=4x^5-8x^4+8x^2-4x$

For roots, $f(x)=0$ .

$4x^5-8x^4+8x^2-4x=0$

$4x(x^4-2x^3+2x-1)=0$

$4x((x^4-1)+(-2x^3+2x))=0$

$4x((x^2+1)(x^2-1)-2x(x^2-1))=0$

On further simplification, we get

$4x(x^2+1-2x)(x^2-1)=0$

$4x(x-1)^2(x+1)(x-1)=0$

$4x(x+1)(x-1)^3=0$

Using zero product property, we get

$4x=0$

$x=0$

Similarly,

$x+1=0$

$x=-1$

And,

$(x-1)^3=0$

$x=1$

Therefore, the zeroes of the given function are $-1,0,1$ and the factor form of the given function is $f(x)=4x(x+1)(x-1)^3$ .

Factor as the product of two binomials. 36+12x+x^2=

Snezhnost [94]

Answer:

(6 + x)(6 + x) = (6 + x)²

Step-by-step explanation:

Given

36 + 12x + x²

Consider the factors of the constant term (+ 36) which sum to give the coefficient of the x- term (+ 12)

The factors are + 6 and + 6, since

6 × 6 = 36 and 6 + 6 = 12, thus

36 + 12x + x² = (6 + x)(6 + x) = (6 + x)²

Decide whether the given expression is a polynomial and tell why or why not.

HACTEHA [7]

Answer:

3x² – 5x + 2 is a polynomial because:

Exponents are whole numbers, and the expression has at least 1 term.

Exponents other than whole numbers can take the form of variables in denominators, and roots which we don't want.
