Answer: $17.82

Step-by-step explanation: Add each item up to get $19.80. Then you take 10% of that by multiplying it 0.9 to get 17.82. You multiply it by 0.9 because that is 90% of 19.80 which is a 10% decrease.

kompoz [17]

Answer:

Let X the random variable of interest "Number of correct anwers on the tet", on this case we now that:

$X \sim Binom(n=10, p=0.25)$

And the expected value is given by:

$E(X) = np =10*0.25 = 2.5$

Step-by-step explanation:

Previous concepts

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

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".

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

Let X the random variable of interest "Number of correct anwers on the tet", on this case we now that:

$X \sim Binom(n=10, p=0.25)$

And the expected value is given by:

$E(X) = np =10*0.25 = 2.5$

The quotient of a number and 5 less 10 is 3

ohaa [14]

Quotient means the answer of diving two numbers.

We can write the equation as: n/5 - 10 = 3

~Add 10 to both sides

n/5 - 10 + 10 = 3 + 10

n/5 = 13

1/5n = 13

1/5n * 5 = 13 *

n = 65

Hope This Helped! Good Luck!
