Answer:The importance of sample size calculation cannot be overemphasized. A research can be conducted for various objectives. A smaller sample will give a result which may not be sufficiently powered to detect a difference between the groups and the study may turn out to be falsely negative leading to a type II error.
4(2x-7)=8x-28
4(-4x+18)=-16x+72
(8x-28)-(-16x+73)
24x+45
4s+7a=861
s+a=168
This can be solved using either elimination or substitution. I am going to use substitution.
Solve s+a=168 for s
s=168-a
Replace 168-a for s in 4s+7a=861
4(168-a)+7a=861
672-4a+7a=861
Solve for a
672+3a=861
3a=189
a=63
Substitute 63 for a in s=168-a
s=168-63=105
So, s=105 student tickets and a=63 adult tickets
We have the following function:
F (t) = Ao * (b) ^ (k * t)
For this case we observe that t is a variable.
We observe that an independent variable.
The function F (t) depends on t.
In this case t is time and can be expressed in seconds, minutes, hours, days, weeks, months and years.
Answer:
time
option A
