The conditions required for a random variable X to follow a Poisson process. The probability of success is the sme for aany two intervals of equal length. The probability of two or more successes in any sufficiently small subinterval is 0.

<h3>Is the time required to upload a file to the Internet discrete or continuous?</h3>

Is the length of time it takes to download a file from the Internet a random variable, a continuous random variable, or not at all? A continuous random variable, that is.

<h3>Is the a discrete random variable a continuous random variable or not a random variable?</h3>

A variable whose value is determined by counting is referred to as a discrete variable.
A continuous variable is one whose value may be determined through measurement.
A random variable is a variable whose value is the resultant number of an unpredictable event.
There are a countable number of potential values for the discrete random variable X.

<h3>How do you determine whether the random variable is discrete or continuous?</h3>

A discrete variable is one that is random.
if the number of possible values is either countable or finite. Continuous refers to a variable that is random.
if the range of possible values includes all conceivable numbers.

Rainbow [258]

Answer:

Step-by-step explanation:

This is a binomial probability distribution because there are only 2 possible outcomes. It is either a randomly selected student grabs a packet before being seated or the student sits first before grabbing a packet. The probability of success, p in this scenario would be that a randomly selected student sits first before grabbing a packet. Therefore,

p = 1 - 0.81 = 0.91

n = 9 students

x = number of success = 3

The probability that exactly two students sit first before grabbing a packet, P(x = 2) would be determined from the binomial probability distribution calculator. Therefore,

P(x = 2) = 0.297

Which statement best illustrates using the vertical line test to determine if the graph below is a function of x ?

kirill115 [55]

If something is a function, every x-value, only has one (1) y-value. If the line x = 0 intersects the graph in two points, there are to values for y (instead of one). Therefore the graph is not a function of x.

Your answer is A.

Each batch of ms.crawley's cookies makes 14 cookies. if sandy needs 8 dozen cookies for her bake s how many batches does she hav

erica [24]

7 batches. There is 12 cookies in a dozen so multiply 8×12 to get 96 cookies. 96 Is the total cookies you need to make. So if you divide 96 by the 14 to see how many batches you must make. you will get a number of 6.85... so you must round up to 7.

For each of the following, state the equation of a perpendicular line that passes through (0, 0). Then using the slope of the ne

SVEN [57.7K]

Answer:

The answer is below

Step-by-step explanation:

a) y=3x-1

The standard equation of a line is given by:

y = mx + c

Where m is the slope of the line and c is the intercept on the y axis.

Given that y=3x-1, comparing with the standard equation of a line, the slope (m) = 3, Two lines with slope a and b are perpendicular if the product of their slope is -1 i.e. ab = -1. Let the line perpendicular to y=3x-1 be d, to get the slope of the perpendicular line, we use:

3 × d = -1

d = -1/3

To find the equation of the perpendicular line passing through (0,0), we use:

$y-y_1=d(x-x_1)\\d\ is\ the \ slope:\\y-0=-\frac{1}{3} (x-0)\\y=-\frac{1}{3}x$

To find x if the point P(x, 4) lies on the new line, insert y = 4 and find x:

$y=-\frac{1}{3}x\\ 4=-\frac{1}{3}x\\-x=12\\x=-12$

b) y=1/4 x+2

Given that y=1/4 x+2, comparing with the standard equation of a line, the slope (m) = 1/4. Let the line perpendicular to y=1/4 x+2 be f, to get the slope of the perpendicular line, we use:

1/4 × f = -1

f = -4

To find the equation of the perpendicular line passing through (0,0), we use:

$y-y_1=f(x-x_1)\\f\ is\ the \ slope:\\y-0=-4 (x-0)\\y=-4x$

To find x if the point P(x, 4) lies on the new line, insert y = 4 and find x:

$y=-4}x\\ 4=-4x\\x=-1$
