Answer:
f(-3)=-21
Step-by-step explanation:
f(x)=-x2-12
f(-3)=-(-3)2-12
f(-3)=-9-12
f(-3)=-21
Suppose there are n observations in a data set consisting of the observations x1, x2, x3, ..., xn.
Rounding rule: round to one more decimal place than the highest number of decimal places contained in the data.
The formula can also be represented as sigma * xi / n.
x bar = SAMPLE MEAN
Mu = POPULATION MEAN
n= sample size
N= POPULATION SIZE
The sum of the deviations from the mean is always equal to 0.
The mean will always be pulled towards any outliers.
Ex: the average price of similar televisions at different stores. This is quantitative data that does not have outliers since the TVs at the different stores are similar
Answer:
option A is the correct option
The Length of third side of the triangle is 4x +5
What is the Triangle?
A triangle is a three-sided polygon that consists of three edges and three vertices. The most important property of a triangle is that the sum of the internal angles of a triangle is equal to 180 degrees. This property is called angle sum property of triangle.
How to determine the length of the third side of the Triangle?
The given parameters are:
Length of the first side = 3x+2
Length of the second side =7x-4
Perimeter of the triangle =14x+3
Now, The perimeter is the sum of the sides of lengths
So, we have
Perimeter = sum of the sides of lengths
According to the question:
14x+3 =3x+2 +7x -4 + third side
Evaluate the like terms
14x-10x = -2 -3
third side = 4x + 5
Hence, The length of the third side of the triangle is 4x+5
