Using the binomial distribution, it is found that the mean and the standard deviation of variable x are given as follows:
<h3>What is the binomial probability distribution?</h3>
It is the probability of exactly <u>x successes on n repeated trials, with p probability</u> of a success on each trial.
The expected value of the binomial distribution is:
E(X) = np
The standard deviation of the binomial distribution is:
In this problem, we have that the parameters are given as follows:
n = 4, p = 0.75.
Hence the mean and the standard deviation are given as follows:
- E(X) = np = 4 x 0.75 = 3.

Okay so i cant just post what the answer is i have to type something.
but anyways this is the answer: t= 4.56
Answer:
a³b < 0
Step-by-step explanation:
If a > 0 then a³ > 0
and b < 0
then
a³b → + × - → -
that is a³b < 0
Answer: 2 / 5x
Explanation:
Answer:
<u>Approximately there are 3,785.6 milliliters in one gallon </u>
Step-by-step explanation:
Let's find out how many milliliters are there in one gallon.
1 US Cup = 236.6 ml (actual equivalence)
Let's recall that:
16 US Cups = 1 US Gallon
Therefore,
1 US Gallon = 16 * 236.6 ml
1 US Gallon = 3,785.6 ml
<u>Approximately there are 3,785.6 milliliters in one gallon</u>
