Answer:
2.565 × 10^-12
Step-by-step explanation
multiply 3.42 and 7.5
you will get 25.65
multiply that by 100
then after add the powers( index law) you will get -13
minus -13 to get -12 because you multiplied by 100
Answer:
And adding the values we got:

Step-by-step explanation:
Assuming this question: P(X≥14), n=18, p=0.8
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".
Solution to the problem
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
And we want this probability:

And we can find the individual proabilities using the probability mass function:
And adding the values we got:

Answer:

Step-by-step explanation:
Distance between two points:
Suppose that we have two points,
and
. The distance between them is given by:

Distance from A(-8,-3,-2) and B(-4,8,0)



Answer:
x = 1
Step-by-step explanation:
To solve for a variable, you need to get the variable on one side of the equation, and by itself.
4x + 5 = x + 8
4x = x + 3 --- subtract 5 from both sides
3x = 3 --- subtract x from both sides
x = 1 --- divide both sides by 3
The derivative of constant numbers is zero.
