16 to both sides! How you get this is that you take the middle number, which is 8, divide it by 2, and square it. 8 divided by 2 is 4, and 4 squared is 16. :)
Answer:
y = x/3
Step-by-step explanation:
y = 3x
x = 3y
3y = x
y = x/3
Answer:
12.5 units or 12 1/2 units
Step-by-step explanation:
From the question, it uses 7.5 units in 3 hours.
In one hour it will use; 7.5/3 = 2.5 units
If 2.5 units is used in 1 hour
In 5 hours; 5 × 2.5 units will be used. This gives us 12.5 units or 12 1/2 units.
Focus on triangles DFC and DFE. They are both right triangles, and they share the side DF. Moreover, we have DE=DC.
So, the two triangles are congruent, because they are two right triangles with the same hypotenuse and a common leg.
So, the other legs must be equal as well, and we have
which implies
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.
