Answer:

Option A. is the solution

Step-by-step explanation:

The equation of the line is y = - 9x + 4

We will plug in the values of each ordered pair given in the options. If they satisfy the equation, will be the solution of the eqaution.

Option A.

(10, -86)

-86 = - 9(10) + 4

-86 = -90 + 4

-86 = -86

Therefore, this ordered pair is the solution of the equation.

Option B.

(-4, -58)

-58 = -9(-4) + 4

-58 = 36 + 4

-58 = 40

Not the solution of the equation.

Option C.

(6, -41)

-41 = -9(6) + 4

-41 = -54 + 4

-41 = -50

Not the solution of the equation.

Option D.

(-6, 57)

57 = -9(-6) + 4

57 = 54 + 4

57 = 58

Not the solution of the equation.

What is 6x to the 3 fifths in radical form

DerKrebs [107]

Assuming you mean $6x^ \frac{3}{5}$ and not $(6x)^ \frac{3}{5}$

remember
$x^ \frac{m}{n}= \sqrt[n]{x^m}$ so

$6x^ \frac{3}{5}$ = $6 \sqrt[5]{x^3}$

Question 9 of 10

harkovskaia [24]

Out of the two parallelograms shown, we can say that A. Both I and II; congruent diagonals property.

<h3>Which of the shapes is a rectangle?</h3>

Rectangles can be proven to be rectangles by the congruent diagonals property.

This states that rectangles should be able to have diagonal lines extending from all sides within the rectangle that are perpendicular to each other.

These lines should bisect each other. As shown in the daigram, both shapes have that quality and so are both rectangles.

The computer that controls a bank's automatic teller machine crashes a mean of 0.6 times per day. What is the probability that,

professor190 [17]

Answer:

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

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

In which

x is the number of sucesses

e = 2.71828 is the Euler number

$\mu$ is the mean in the given interval.

Mean of 0.6 times a day

7 day week, so $\mu = 7*0.6 = 4.2$

What is the probability that, in any seven-day week, the computer will crash less than 3 times? Round your answer to four decimal places.

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)$

In which

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

$P(X = 0) = \frac{e^{-4.2}*(4.2)^{0}}{(0)!} = 0.0150$

$P(X = 1) = \frac{e^{-4.2}*(4.2)^{1}}{(1)!} = 0.0630$

$P(X = 2) = \frac{e^{-4.2}*(4.2)^{2}}{(2)!} = 0.1323$

$P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2) = 0.0150 + 0.0630 + 0.1323 = 0.2103$

0.2103 = 21.03% probability that, in any seven-day week, the computer will crash less than 3 times.
