Answer:
The approximate estimate of the standard deviation of the speeding ticket fines is of 12.41.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
Approximately 68% of the measures are within 1 standard deviation of the mean.
Approximately 95% of the measures are within 2 standard deviations of the mean.
Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Middle 68% of speeding ticket fines on a highway fall between 93.18 and 118.
This means that 93.18 is one standard deviation below the mean and 118 is one standard deviation above the mean. That is, the difference between 118 and 93.18 is worth two standard deviations. So
The approximate estimate of the standard deviation of the speeding ticket fines is of 12.41.
Answer:
Congruent
Step-by-step explanation:
Congruent figures are all figures that have the same number of sides, with the same length, and the angles between the sides have the same values.

Answer:
B) m = -1 , x + y = 9
Step-by-step explanation:
Answer:
○ 
Step-by-step explanation:
Use the Triangular Interior Angles Theorem to figure this out:
180° = [3x]° + [2x]° + [5x]°
![\displaystyle \frac{180°}{10°} = \frac{[10x]°}{10°} \\ \\ 18 = x](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Cfrac%7B180%C2%B0%7D%7B10%C2%B0%7D%20%3D%20%5Cfrac%7B%5B10x%5D%C2%B0%7D%7B10%C2%B0%7D%20%5C%5C%20%5C%5C%2018%20%3D%20x)
Plug this back into the <em>m</em>∠<em>L</em><em> </em>to get 54°.
