Answer:
B) f(x) = x if x ≤ -2
2 if x > -2
Step-by-step explanation:
B) f(x) = x if x ≤ -2 (The x and y coordinate have the same value)
2 if x > -2
Using the Empirical Rule, it is found that 95% of the employees will have a travel time within the following range:
B. 8 minutes to 28 minutes.
<h3>What does the Empirical Rule state?</h3>
It 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.
Considering that the mean time is 18 minutes and the standard deviation is 5 minutes, the the bounds of the 95% range are given by:
Hence option B is correct.

Answer:
x=1.33 repeating or 1 1/3
Step-by-step explanation:
You take 4 and distribute to everything in the parentheses.
You also do the same for the -4.
After you distribute, you should get: 4x+24=-8x+36+3x
Then you combine like terms (the two x's on the right side of the equation.
You should then get: 4x+24=-5x+36
Next, you subtract 24 from the positive 24, to cancel it out, and the 36 to get 12.
Then, add 5x to the negative 5x, to cancel it out, and to the 4x to get 9x.
Finally, you divide 12 by 9 to get 1.33 repeating or 1 1/3.
The answer is x=15 hope this is right
