What value of k will result in the quadratic having one rational solution if 4x2+kx+4=0?

PtichkaEL [24]

The value of 'k' in the quadratic Equation $4x^{2}+kx+4=0$ having one rational solution is k is 8.

<h3>What is a Quadratic Equation?</h3>

Quadratic equations are the polynomial equations of degree 2 in one variable of the type $f(x) = ax^{2} + bx + c = 0$ where a, b, c, ∈ R and a ≠ 0.
The standard form of a quadratic equation is $ax^{2} + bx + c = 0$ .

Here, the given equation is $4x^{2}+kx+4=0$

By comparing the given equation with the standard form of the quadratic equation we get,

a = 4

b = k

c = 4

The given quadratic is having one rational solution, which means $b^{2} -4ac=0$

Therefore,

$k^{2} -4 \times 4\times4=0\\k^{2} -64=0\\k^{2} =64\\k=\sqrt{64} \\k=8$

Therefore, the value of k is 8.

Answer:

10000*0.6065=6065

A. about 6,065

Step-by-step explanation:

Definitions and concepts

The Poisson process is useful when we want to analyze the probability of ocurrence of an event in a time specified. The probability distribution for a random variable X following the Poisson distribution is given by:

$P(X=x) =\lambda^x \frac{e^{-\lambda}}{x!}$

And the parameter $\lambda$ represent the average ocurrence rate per unit of time.

For this distribution the expected value is the same parameter $\lambda$

$E(X)=\mu =\lambda=0.5$ , $Var(X)=\lambda=0.5$ , $Sd(X)=707$

Solution to the problem

We want "how many would have no blemishes" so first we need to find the probability that X=0, since X represent on this case the number of blemishes on each door. And if we use the mass function we got this:

$P(X=0) =0.5^0 \frac{e^{-0.5}}{0!}=0.6065$

And now since we have a total of 10000 doors painted we can find how many we would expect with no blemishes:

10000*0.6065=6065

A. about 6,065

O COUNTING AND PROBABILITY

valina [46]

Answer:

a. $Odds = \frac{3}{7}$

b. $Odds = \frac{7}{3}$

Step-by-step explanation:

Given

$n(Black) = 7$

$n(Grey) = 2$

$n(White) = 1$

$n(Total) = 10$

Solving (a): Odds against winning

Since, the arrow must stop at black, then

The odds against winning is calculated as thus:

$Odds = \frac{n(Total) - n(Black)}{n(Black)}$

$Odds = \frac{10 - 7}{7}$

$Odds = \frac{3}{7}$

Solving (b): Odds in favor of winning

Since, the arrow must stop at black, then

The odds is calculated as thus:

$Odds = \frac{n(Black)}{n(Total) - n(Black)}$

$Odds = \frac{7}{10 - 7}$

$Odds = \frac{7}{3}$

What are the closest integers that the square root of 300 is in between?

cricket20 [7]

They are 17 and 18! The square root of 300 is 17.32 (rounded to the nearest tenth). The integer (or whole number) below that is 17. The whole number above it is 18. Therefore, the square root of 300 is between them.
Hope that helps! :)

Chlorine, which is used to clean swimming pools, exists as two chlorine atoms covalently bonded to each other.How many valence e

timurjin [86]

Answer: Each chlorine has 7 valence electrons.

Step-by-step explanation: Chlorine is an element with atomic number 17 and thus contains 17 electrons. Valence electrons are the electrons which are present in the valence shell.

Electronic configuration of chlorine:

$Cl:17=1s^22s^22p^63s^23p^5$

Chlorine atom has 7 valence electrons (2 in 3s and 5 in 3p orbital) and thus need to share one electron with other chlorine atom to complete its octet and attain stability.
