Answer:
X=1
Step-by-step explanation:
6 times x = 6x
6 times positive 3 = 18
6x +18 = 24
-18 -18
6x = 6
6 6
x = 1 :)
Answer:
(a) The sample variance is 16.51
(a) The sample standard deviation is 4.06
Step-by-step explanation:
Given
Solving (a); The sample variance.
First, calculate the class midpoints.
This is the mean of the intervals.
i.e.
So, the table becomes:
Next, calculate the mean
Next, the sample variance is:
So, we have:
The sample standard deviation is:
The answer would be 5/27
(If you want me to explain I can)
Hope this helps
Have a great day/night
Answer:
y = -1/3x + 5
