Answer:
x=8
Step-by-step explanation:
9 3
---- = -----
24 x
Using cross products
9 * x = 3 * 24
Divide each side by 9
9x/9 = 3*24/9
x = 3/9 * 24
x = 1/3 *24
x = 8
This is a simple problem! So let’s start. The rule a negative and a negative makes a positive plays a role in here so then we can switch it to -6+9 now subtract 9 to 6 and you get 3. That will be your answer. You can switch the numbers around to make it easier that what I like to do. For example, instead of having -6+9 you could instead do 9-6!
Hope this helps!
If I’m wrong say it in comments I don’t want it to harm others.
Answer:
6 pounds
Step-by-step explanation:
2.7/0.45 = 6
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.
