6(t-3)=2(9-2t)=
We move all terms to the left:
6(t-3)-(2(9-2t))=0
We add all the numbers together, and all the variables
6(t-3)-(2(-2t+9))=0
We multiply parentheses
6t-(2(-2t+9))-18=0
We calculate terms in parentheses: -(2(-2t+9)), so:
2(-2t+9)
We multiply parentheses
-4t+18
Back to the equation:
-(-4t+18)
We get rid of parentheses
6t+4t-18-18=0
We add all the numbers together, and all the variables
10t-36=0
We move all terms containing t to the left, all other terms to the right
10t=36
t=36/10
<h2>
t=3+3/5</h2>
2 I think sorry if I'm wrong.
The answer to that is (the product)
Answer:
The standard error of the sample mean is _17.677_ psi.
Step-by-step explanation:
<u>Explanation</u>:-
A random sample of n = 8 specimens is collected.
Given sample size is n = 8
Given mean of the population 'μ' = 2500 psi
standard deviation 'σ' = 50 psi
Let x⁻ is the mean of the observed sample
Standard error of the sample mean = ...(i)
Given Population of standard error (S.D) 'σ' = 50 psi
Now substitute all values in (i)
<u>Conclusion</u>:-
The standard error of the sample mean is _17.677psi.
