Answer:
sample variance
the value of the one observation
the mean value of all observations
the number of observations
Step-by-step explanation:
Answer:
answer is the number 5
Step-by-step explanation:
First you square root 9 which is 3. Then u 3-1= 2. then u times 2 by 6 which equals = 12. Then minus 7 from this number. 12-7=5 ur number is 5.
Given:
A figure of a right triangle and an altitude form the right angle vertex to hypotenuse.
To find:
The value of x.
Solution:
From the given figure, it is clear that the altitude divides the hypotenuse in two segments x and 8.
Length of altitude = 18
If an altitude divide the hypotenuse in 2 segments, then according to the geometric mean theorem, the length of the altitude is the geometric mean of two segments of hypotenuse.
By using geometric mean theorem, we get
Divide both sides by 8.
Therefore, the value of x is 40.5.
Answer: Put a dot at (-3, 5).
Step-by-step explanation: The vertex is the point of which the parabola is at its maximum or minumum.
