Answer: 24,179 - 3000y
Step-by-step explanation: Each year the car goes down by 3000 since you said it was decreasing, so y represents the year and you eould out it next to the 3000 to represent that 3000 is being decreased every year.
We know that two complements add up to 90.
Let's call the smaller angle x and the larger y.
3x = y
x + y = 90
We can use simple substitution.
x + 3x = 90
4x = 90
x = 22.5
Then, since we know that 3x=y, we can find the larger angle.
3*22.5 = 67.5
In order to find the volume of a triangular pyramid, you must use the formula (abh)/6. Therefore, I believe the answer is 12 (if [a = a] [b = h] and [c = b]).
Let d represent the number of days she rented the bicycle.
123 = 55 + 8.50d
Answer:
Option D is correct.
The margin of error accounts for all of the other listed options in a confidence interval.
Step-by-step explanation:
Confidence Interval for the population mean is basically an interval of range of values where the true population mean can be found with a certain level of confidence.
Mathematically,
Confidence Interval = (Sample mean) ± (Margin of error)
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error of the mean)
The width around the sample mean provided by the margin of error for the population mean helps to cover a lot of factors that are usually beyond one's control for the population parameter.
All the three options provided, response bias, random chance and small sampling biases all introduce deviations from the sample mean for the population mean. Hence, the width afforded to the possible values of the population mean creates avenue for all of these factors to be incorporated and the range of values becomes more inclusive.
Hence, the width provided by the margin of error about the sample mean accounts for response biases, random chance and small sampling biases.
Hope this Helps!!!
