What is the solution of the system of equations? y = –4x + 6 y = –5x – 4

zaharov [31]

Y= -4x + 6 (-10, 46), (-1.11, 10.44),

y= -5x -4. (-10, 46)

whereas (-10, 46) is the solution for both equations, it is the correct choice

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

Answer:

x = 1/4

Step-by-step explanation:

Solve for x:

1 - 2 (1 - 2 x) = 0

Hint: | Distribute -2 over 1 - 2 x.

-2 (1 - 2 x) = 4 x - 2:

4 x - 2 + 1 = 0

Hint: | Group like terms in 4 x - 2 + 1.

Grouping like terms, 4 x - 2 + 1 = 4 x + (1 - 2):

4 x + (1 - 2) = 0

Hint: | Evaluate 1 - 2.

1 - 2 = -1:

4 x + -1 = 0

Hint: | Isolate terms with x to the left hand side.

Add 1 to both sides:

4 x + (1 - 1) = 1

Hint: | Look for the difference of two identical terms.

1 - 1 = 0:

4 x = 1

Hint: | Solve for x.

Divide both sides by 4:

Answer: x = 1/4
