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?
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%.
Answer: The simplest form of the ratio would be 50:13.
If we use the values in the problem, we have a ratio of 1:0.26. The problem is that we have a decimal value and we should use whole numbers.
Start by multiplying each value by 100 to eliminate the decimal.
We have 100:26.
Now, each value contains a factor of 2. So divide by 2 and we get 50:13.

Answer:
Minimum Unit Cost = $14,362
Step-by-step explanation:
The standard form of a quadratic is given by:
ax^2 + bx + c
So for our function, we can say,
a = 0.6
b = -108
c = 19,222
We can find the vertex (x-coordinate where minimum value occurs) by the formula -b/2a
So,
-(-108)/2(0.6) = 108/1.2 = 90
Plugging this value into original function would give us the minimum (unit cost):
