The slope of the line below is 3. Which of the following is the point slopeform of the ling?O A. y-2=3(446)O B. y-6--3/442)O C.

polet [3.4K]

The slope of the line is given as -3 and it passes through the point (2, -6).

Thus we can write the equation of the line in point-slope form;

$\begin{gathered} \frac{y-y_1}{x-x_1}=-3 \\ \frac{y-(-6)}{x-2}=-3 \\ \frac{y+6}{x-2}=-3 \\ y+6=-3(x-2) \\ \end{gathered}$

Therefore, the correct option is D

If a baseball player has 5 hits in 20 at bats, what is the probability in the decimal to the thousandths place that he will get

k0ka [10]

Answer:

$Probability = 0.250$

Step-by-step explanation:

Given

$Hits = 5$

$Bats = 20$

Required

Determine the probability of hit in next at-bat

This question illustrates theoretical probability and the required probability is calculated using:

$Probability = \frac{Events\ Occurrence}{Trials}$

In this case, we have:

$Probability = \frac{Hits}{Bats}$

$Probability = \frac{5}{20}$

$Probability = 0.250$

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.
