It would seem the problem requires you compute the mean, median, and standard deviation of each of the data sets. This is nicely done using the statistics functions of your graphing calculator.
Data Set A (mean, median, standard deviation) = (29.7, 29.5, √12.71)
Data Set B (mean, median, standard deviation) = (27.95, 27, √6.1475)
1. False. Data Set B is skewed to the right.
2. TRUE. 27.95 is within 3 of 29.7.
3. False. √12.71 ≠ √6.1475
4. False. The mean of Data Set A is 29.7.
5. False. Data Set A has the higher standard deviation.
6. TRUE. 29.7 is close to 29.5.
The true statements are
• the 2nd one
• the 6th one
For a problem of this nature, we need to assume that the base of the observation tower is at the same elevation as the fire. The tangent of the angle is the ratio of tower height to horizontal distance:
tan(α) = (tower height)/(horizontal distance)
Rearranging this equation, we have
(horizontal distance) = (tower height)/tan(α)
Putting in the given values gives
(horizontal distance) = (90 ft)/tan(7°) ≈ 733 ft
Answer:
The slope is 9.5
The equation is y = 9.5x
Step-by-step explanation:
The equation is in the form of y = mx + b, where m represents the slope.
In the case of our situation, y = 9.5x , b = 0 and m = 9.5
9.5 is the slope because that is the rate of change as x increases per ticket sale
The answer would be x = 4 miles.
The answer would be the last one.
