Answer:
Standard error
Step-by-step explanation:
The standard deviation of the distribution of sample means is called the standard error of the means.
It is denoted by: 
The standard error is calculated using the formula: 
where n is the sample size and 
is the population standard deviation.
Answer:
x can be divided by 2,3,4,5,6
2 can be divided by 4, so is 3 to 6
so simply x can be divided by 4,5,6
4*5*6=120
Step-by-step explanation:
A table titled hours spent studying has entries 4, 5, 9, 15, 8, 2, 20, 1, 6, 9, 10, 8, 10, 8, 1, 2.
Sauron [17]
The range is the maximum value minus the minimum value. In this case would be 20 - 1 which is 19.
Answer:
Step-by-step explanation:
Vertex form of the quadratic equation: 
where the vertex is 
Given vertex = (6, 5):
If one the x-intercepts is (8, 0):
Therefore, equation of parabola:
x-intercepts occur when f(x) = 0:
Therefore, the x-coordinate of the other x-intercept is 4.
