Answer:
Approximately 1,552.42.
Step-by-step explanation:
To round the result of $25,625 divided by 16.5 to the nearest hundredth, you need to perform the division first and then round the quotient. Here are the steps:
1. Divide $25,625 by 16.5:
$25,625 ÷ 16.5 = 1,552.42
2. Now, round the quotient, 1,552.42, to the nearest hundredth.
The hundredths place is the second decimal place after the decimal point.
- If the third decimal place is 5 or greater, you round up the second decimal place.
- If the third decimal place is less than 5, you keep the second decimal place as it is.
In this case, the second decimal place is 4, so we keep it as it is.
Therefore, rounding $25,625 divided by 16.5 to the nearest hundredth gives us:
$25,625 ÷ 16.5 ≈ 1,552.42
So, when rounded to the nearest hundredth, $25,625 divided by 16.5 is approximately 1,552.42.
Hope this helps.

The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The margin of error of the survey will be ±4%.
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The results of a survey indicate that between 76% and 84% of the season ticket holders are satisfied with their seat locations. Therefore, the margin of error can be written as,
Margin of Error = (84%-76%)/2 = 8%/2 = ±4%
Hence, the margin of error of the survey will be ±4%.

Answer:
±4
Step-by-step explanation:
The margin of error in a confidence interval is half the range:
(84 - 76) / 2 = 4
So the margin of error is ±4.
Answer:
175 hot dogs
Step-by-step explanation:
The new price will be $3.85 + 0.55 = $4.40. Since the price has increased by a factor of 4.40/3.85 = 8/7, the number of hot dogs sold, which is inversely proportional, will be ...
(7/8)·200 = 175 . . . hot dogs sold at the higher price
The vendor can expect to sell approximately 233 hot dogs if the price is increased by 55 cents.
To determine how many hot dogs the vendor can expect to sell if the price is increased by 55 cents, we can use the inverse proportionality relationship between the number of hot dogs sold and the price charged.
First, let's set up a proportion with the initial price and number of hot dogs sold:
$3.85 / 200 = (new price + $0.55) / x
Next, we can cross multiply and solve for x:
x = (200 * ($3.85 + $0.55)) / $3.85
Calculating this expression gives us a value of x ≈ 233.77.
Since the number of hot dogs sold must be a whole number, we round down to the nearest whole number, giving us an estimated value of 233 hot dogs.
