The rectangle was basically cut into two right angles so all you have to find is the length of the triangle. Using what we know which is the h<span>ypotenuse and the height, use the equation x= the square root of c^2 - a^2.
The base is x = 9.17 in</span>

Step-by-step explanation:
x=v*(y-3)
x=vy/4w
x=(3+w)/v
x=(y-6w)/v
Answer:
All values are identical.
Step-by-step explanation:
We are given the following in the question:
If the standard deviation of a set of data is zero.
Then, all the values in data are identical.
This can be shown as:
Let all the terms in data be x.
Formula:
where 
are data points, 
is the mean and n is the number of observations.
Sum of squares of differences =
Thus, the correct answer is
All values are identical.

Answer:
Step-by-step explanation:
as mode is 45 ,two of three is 45
i assume x =y=45
now (41+46+45+45+z)/5=50
177+z=50×5=250
z=250-177=73
so x=45
y=45
z=73
