Simplify and find the undefined values of (3x^2+18)/(4x^4+24x^3)

1 answer:

8 0

Answer: x=0 ; x=-6
The result of the equation would be undefined if the denominator is zero. In this question, the denominator is(4x^4+24x^3). You need to simplify the equation to find the number.
(3x^2+18) / (4x^4+24x^3)
3(x^2+6) / 4x^3(x+6)

You can find 2 results of variable x that will result in zero value of denominator.1. 4x^3=0
x=0
2. x+6=0
x=-6

A paint-store chain produces and sells latex and semigloss paint. Based on long-range sales, the probability that a customer wil

Flauer [41]

Answer:

The probability that the paint latex = 0.857

Step-by-step explanation:

From the given information:

Let consider X to be the event that the customer has purchased the latex paint

Let consider Y to be the event that the customer has purchased semigloss paint.

Now, the probability of X i.e. P(X) = 0.75

SInce X and Y are mutually exhaustive)

P(Y) = 1 - P(X)

P(Y) = 1 - 0.75

P(Y) = 0.25

Similarly, Let Consider Z be the event that the customer has purchased a roller.

We are being told that P(Z|X) = 0.6

P(Z|Y) = 0.30

$P(X|Z) = \dfrac{P(Z|X)(P(X) }{P(Z|X)*P(X)+P(Z|Y)*P(Y)}$

$P(X|Z) = \dfrac{0.6 \times 0.75 }{(0.6 \times 0.75) +(0.3 \times 0.25)}$

$P(X|Z) = \dfrac{0.45 }{(0.45) +(0.075)}$

$P(X|Z) = \dfrac{0.45 }{0.525}$

$P(X|Z) = 0.857$

Thus, the probability that the paint latex = 0.857

Does anyone know how to do this? please help me

Elis [28]

On the x column, you would write 1, 2, 3, 4, and so on. Then, in the y box, you plug in that number into the equation. Write your answer in the y column.

For example, if x = 1, then 1^2 + 2 - 8 = - 5.
If x = 1, y= -5

Answer:

99/14

Step-by-step explanation:

(3.25 + 2/7) / ( 3/5 * 5/6)=(3.25+2/7) / (1/2)=(3.25+2/7)*2=(99/28)*2=99/14
