Line AB is Perpendicular to line BC. A=(-3,2) and C=(2,7). Which of the following could be the coordinates of B? Select all that

Llana [10]

Answer:

The answer would be Choice F; (-3,7)

Step-by-step explanation:

Plot the two guaranteed given points
A, (-3,2) and C, (2,7)
Find the point where the x and y would share and then form a right angle. This is called being Perpendicular.
So, take the <em>x</em> of A, and the <em>y</em> of C and you have the coordinates of B.

Answer:

$P(X \geq 2) = 1-P(X$

And we can find the individual probabilities using the probability mass function and we got:

$P(X=0) = (30C0) (0.05)^0 (1-0.05)^{30-0} =0.2146$

$P(X=1) = (30C1) (0.05)^1 (1-0.05)^{30-1} = 0.3389$

And replacing we got:

$P(X \geq 2) = 1-P(X$

Step-by-step explanation:

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=30, p=0.05)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

Solution to the problem

For this case we want this probability:

$P(X \geq 2)$

And we can use the complement rule and we got:

$P(X \geq 2) = 1-P(X$

And we can find the individual probabilities using the probability mass function and we got:

$P(X=0) = (30C0) (0.05)^0 (1-0.05)^{30-0} =0.2146$

$P(X=1) = (30C1) (0.05)^1 (1-0.05)^{30-1} = 0.3389$

And replacing we got:

$P(X \geq 2) = 1-P(X$

In how many ways can 6 different kinds of pizza be listed on the menu?

vredina [299]

Answer: 720

Step-by-step explanation:

Since we are to list 6 different kinds of Pizza and no condition is attached , this arrangement could be done in 6! ways.

That is

6! = 720

This means that the different kind of pizza could be listed in 720 ways

Compare the values of the underlined digits?

amm1812

The value of 7 in 26,475 is ten times greater than the value of 7 in 503,497.

This is because the first 7 is in the tens place and the second seven is in the ones place. Everytime you move to the next "place" you are basically making the number ten times smaller or greater.
