Answer:
Option B
Step-by-step explanation:
We can see that, from the picture provided, the graphs intersect at points( 0, 4 ) and ( - 4, 4 ), respective to functions f( x ) and g( x ). These intersection points makes each function equivalent to one another, and hence -
Function f( x ) where x = - 4 / Function g( x ) where x = - 4,
![f( - 4 ) = 4,\\g( - 4 ) = 4\\----------\\f ( - 4 ) = g ( - 4 )](https://tex.z-dn.net/?f=f%28%20-%204%20%29%20%3D%204%2C%5C%5Cg%28%20-%204%20%29%20%3D%204%5C%5C----------%5C%5Cf%20%28%20-%204%20%29%20%3D%20g%20%28%20-%204%20%29)
Respectively function f( x ) where x = 0 / Function g( x ) where x = 0,
![f( 0 ) = 4,\\g( 0 ) = 4\\----------\\f ( 0 ) = g ( 0 )](https://tex.z-dn.net/?f=f%28%200%20%29%20%3D%204%2C%5C%5Cg%28%200%20%29%20%3D%204%5C%5C----------%5C%5Cf%20%28%200%20%29%20%3D%20g%20%28%200%20%29)
<u><em>Your solution should be option b, " f(-4) = g(-4) and f(0) = g(0) "</em></u>

Answer: 0.9608
Step-by-step explanation:
Given : A study of the amount of time it takes a mechanic to rebuild the transmission for a 2005 Chevrolet Cavalier shows that
Mean :![\mu=8.4\text{ hours}](https://tex.z-dn.net/?f=%5Cmu%3D8.4%5Ctext%7B%20hours%7D)
Standard deviation : ![\sigma=1.8\text{ hours}](https://tex.z-dn.net/?f=%5Csigma%3D1.8%5Ctext%7B%20hours%7D)
Sample size : ![n=40](https://tex.z-dn.net/?f=n%3D40)
Let
be the sample mean.
The formula for z-score in a normal distribution :
![z=\dfrac{\overline{x}-\mu}{\dfrac{\sigma}{\sqrt{n}}}](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B%5Coverline%7Bx%7D-%5Cmu%7D%7B%5Cdfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%7D%7D)
For ![\overline{x}=8.9](https://tex.z-dn.net/?f=%5Coverline%7Bx%7D%3D8.9)
![z=\dfrac{8.9-8.4}{\dfrac{1.8}{\sqrt{40}}}\approx1.76](https://tex.z-dn.net/?f=z%3D%5Cdfrac%7B8.9-8.4%7D%7B%5Cdfrac%7B1.8%7D%7B%5Csqrt%7B40%7D%7D%7D%5Capprox1.76)
The P-value = ![P(\overline{x}](https://tex.z-dn.net/?f=P%28%5Coverline%7Bx%7D%3C8.9%29%3DP%28z%3C1.76%29%3D%200.960796%5Capprox%200.9608)
Hence, the probability that their mean rebuild time is less than 8.9 hours is 0.9608 .
