The mean exists at 3 and the standard deviation exists 0.87.
Using the binomial distribution, it exists seen that the mean and the standard deviation of X exist given as follows:
<h3>What is the binomial probability distribution?</h3>
The expected value of the binomial distribution exists:
The standard deviation of the binomial distribution exists:
In this problem, the proportion and the sample size exist given as follows:
p = 0.75
n = 4
Therefore, the mean and the standard deviation exist given by:
The mean exists at 3 and the standard deviation exists 0.87.

Step-by-step explanation:
Answer:
<em>(-3, -129)</em>
<em></em>
Step-by-step explanation:
Given
Two lines:
are perpendicular to each other and intersect at point (-8,3).
To find: (P, Q)
Solution:
The two lines intersect at (-8,3).
It means, the equation of line will be satisfied when we put value of x = -8 and y = 3
Putting in the second equation, we will get an equation in P and Q:
Given that two lines are perpendicular.
It means the product of their slopes will be equal to -1.
i.e. 
Slope of a line of the form 
is given as:
So, slopes of given lines are:
Using the condition:
Putting the value of P in equation (1):
So, answer is <em>(-3, -129)</em>
That is a question about perimeter of rectangle.
The perimeter of a geometric shape is the sum of the value of the all sides.
In a rectangle, the opposite sides are cogruentes (equals). For example, look at picture below. In that rectangle, the sides AB and DC are equals, and the sides AD and BC are equals.
So, the sides of that rectangular table are: 1.52m, 1.52m, 0.75m and 0.75.
Therefore, the perimeter of that rectangle is 
m.
But that is not the final answer because that is the perimeter in meters and the question want the answer in centimeters.
1 meter has 100 centimeter, so we need to multiplicate the perimeter by 100.
Thus, the perimeter of that rectangular table is 
cm.
