Step-by-step explanation:
Mark as brainllest
2x+5=12
Subtract 5 from both sides
=2x=7
Divide by 2
X=2/7
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:



X+y= -12
xy=8
y=8/x
x+8/x=-12
x^2+12x+8=0
This has no integral
