Answer:
The null hypothesis ![H_o : \mu = 31](https://tex.z-dn.net/?f=H_o%20%3A%20%20%5Cmu%20%3D%20%2031)
The alternative hypothesis ![H_a : \mu > 31](https://tex.z-dn.net/?f=H_a%20%3A%20%20%5Cmu%20%3E%20%2031)
Step-by-step explanation:
From the question we are told that
The population mean is ![\mu = 31 \ miles / gallon](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%2031%20%5C%20%20miles%20%2F%20gallon)
Generally
The null hypothesis is that the company's new sedan, the Libra, will have an average of ![\mu = 31 \ miles / gallon](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%2031%20%5C%20%20miles%20%2F%20gallon)
This mathematically represented as
The null hypothesis ![H_o : \mu = 31](https://tex.z-dn.net/?f=H_o%20%3A%20%20%5Cmu%20%3D%20%2031)
The alternative hypothesis is that the company's new sedan, the Libra, will have an average better than ![\mu = 31 \ miles / gallon](https://tex.z-dn.net/?f=%5Cmu%20%3D%20%2031%20%5C%20%20miles%20%2F%20gallon)
This mathematically represented as
The alternative hypothesis ![H_a : \mu > 31](https://tex.z-dn.net/?f=H_a%20%3A%20%20%5Cmu%20%3E%20%2031)

Answer
ANGLE SIDE SIDE
Step-by-step explanation: Because you have an angle side side hope this helps
The diagonal AC, along with the base AB and length BC, forms a triangle. The triangle's dimensions are:
AC = 18
∠CAB = 20°
AB = ?
∠ABC = 130°
BC = ?
∠BCA = 180 - 20 - 130 = 30°
Thus, we may apply the sine rule:
sin(BCA) / AB = sin(ABC) / AC
AB = sin(30) * 18 / sin(130)
AB = 11.7 inches
