<span>(f o g)(4) = f(g(4))
so
g(4) = </span><span>-2(4) -6 = -14
</span>f(g(4)) = <span>3(-14) -7 = -49
answer
</span><span> (f o g)(4) = -49</span>
Answer:
The order pair (4,-5) is <u>NOT </u>a solution of the inequality
Step-by-step explanation:
2)
Plug in to see if the order pair (4,-5) is a solution of the inequality
y - 8 < - 4x
-5 - 8 ? -4( 4)
- 13 > -16
So answer:
The order pair (4,-5) is <u>NOT </u>a solution of the inequality
$13.25 + ($0.50 x 8)
I hope this helps you answer your question!
The given statement is false as using stratified sampling guarantees that members of each group within a population will be sampled.
As given in the question,
Systematic sampling guarantees that members of each group within a population will be sampled is a false statement.
- Systematic sampling represents the probability of sampling method based on the group formed at regular intervals.
- Stratified sampling guarantees each subgroup within the population receives proper representation.
Therefore, the given statement is false as using stratified sampling guarantees that members of each group within a population will be sampled.

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.
