The distance between -6 and 15 on a number line is 21.
What is number line?
A straight line with numbers placed at equal intervals or segments along its length. Number line is a straight line with a "zero" point in the middle, with positive and negative numbers listed on either side of zero and going on indefinitely.
Given:
The distance between -6 and 15 on a number line is 9 is true or false.
We have to find the the distance between -6 and 15 on a number line.
According to given question we have
15 - (- 6)
= 15 + 6
= 21
The distance between -6 and 15 on a number line is 9 is false.
Therefore, the distance between -6 and 15 on a number line is 21.

Answer:
Step-by-step explanation:
Given the data:
Year___Actual sale (At) ___forecast(Ft)
2005__450_____________410
2006__495____________ 422
2007__518____________ 443.9
2008_ 563____________ 466.1
2009_584____________ 495.2
2010__
Using the formula :
Ft = Ft-1 + alpha(At-1 - Ft-1)
Ft-1 = previous year forecast
At-1 = previous year actual
Alpha = 0.3
Forecast:
2006:
410 + 0.3(450 - 410) = 422.0
2007:
422 + 0.3(495 - 422) = 443.9
2008:
443.9 + 0.3(518 - 443.9) = 466.1
2009:
466.1 + 0.3(563 - 466.1) = 495.2
2010:
495.2 + 0.3(584 - 495.2) = 521.8
Forecasted value for 2010 = 521.8
Final answer:
By utilizing the method of exponential smoothing with alpha=0.3 and applying the forecasting formula iteratively, the forecasted sales of Volkswagen Beetles for 2010 in Nevada is 525.7 units.
Explanation:
The exponential smoothing method is commonly used in business and economics for forecasting future data in situations where historical data is available. The forecast value for 2010 using exponential smoothing with alpha = 0.30 can be obtained by implementing the provided formula in an iterative manner. This formula takes into account the actual data point from the previous year (At-1) and the forecasted data point for that year (Ft-1).
Let us use the forecast value for 2004 and 2005, which was predicted as 410 for each year, as our initial forecast value (F1).
By applying the formula Ft = Ft-1 + alpha * (At-1 - Ft-1) iteratively for each year from 2006 to 2009, we get:
- Forecast for 2006 (F_2006) would be 410 + 0.30*(450-410) = 422.
- Then, the forecast for 2007 (F_2007) is 422 + 0.30*(495-422) = 443.9.
- The forecast for 2008 (F_2008) is 443.9 + 0.30*(518-443.9) = 466.1.
- For 2009 (F_2009), the forecast is 466.1 + 0.30*(563-466.1) = 496.37.
Using these forecasted rates, we then forecast for the year 2010. The forecast for 2010 (F_2010) is calculated by 496.37 + 0.30*(584-496.37) giving 525.67 (rounded to one decimal place). Hence the forecast for the year 2010 using exponential smoothing with the alpha as 0.30 is estimated to be 525.7 VolksWagen Beetles.

The probability that the sample mean would differ from the population mean by more than 1.8 millimeters is approximately 0.0668.
What is the standard deviation?
A standard deviation (σ) is a measure of the distribution of the data in reference to the mean.
The standard deviation of the population is millimeters. The standard error of the sample mean is then
millimeters.
The probability that the sample mean would differ from the population mean by more than 1.8 millimeters is the probability that it falls outside of the interval . We can use the standard normal distribution to approximate this probability.
First, we need to convert the difference between the sample mean and the population means to standard units.
The difference of 1.8 millimeters is :
standard units.
Then, we can use the standard normal distribution to find the probability that the sample mean falls outside of this interval.
This probability is equal to ,
where is the standard normal cumulative distribution function.
Therefore, the required probability is approximately 0.0668.

Show the value of each digit when writing in expanded form. Use plus signs (+) between the values. Knowing the definition of expanded notation can help. Expanded notation means:
"Writing a number to show the value of each digit. It is shown as a sum of each digit multiplied by its matching place value (ones, tens, hundreds, etc.)."
