Answer:
The correct interpretation of this margin of error is for that the entire population, the percentage of people who would support spending the money to construct the stadium should differ 4%(plus/minus) from 57%, that is, it should be between 57 - 4 = 53% and 57 + 4 = 61%.
Step-by-step explanation:
Margin of error:
The interpretation of a margin of error is that it tells how many percentage points the result found in a sample will differ from the population result.
Of the 655 people who were surveyed, 57% said they would support spending the money to construct the stadium. The poll had a margin of error of 4%. Which is the correct interpretation for this margin of error?

Answer:3 after 0 lol thx
Step-by-step explanation:
Answer:
6n−7n−4+n+10
=6n+−7n+−4+n+10
Combine Like Terms:
=6n+−7n+−4+n+10
=(6n+−7n+n)+(−4+10)
=6
Answer:
=6
Step-by-step explanation:
Answer: Pupulation = A*0.95^t
where t is the numer of hours that has passed, and A is the initial population of the bacteria.
Step-by-step explanation:
If the initial population of bacteria is A.
After one hour we can see that the population has decreaesed by 5%, so the new population is
P = A - 0.5*A = 0.95*A
After other our, the population decreased by 5% again, the new population is:
P = (0.95*A) - 0.5*(0.95*A) = 0.95*0.95*A = A*0.95^2
And so on.
This is an exponential decay, so we can write this relation as:
Pupulation = A*0.95^t
where t is the numer of hours that has passed, and A is the initial population of the bacteria.
