Essentially, you would take the formula for the laws of sines and cosines: a^2=b^2+c^2-2bc(Cos(theta)). a is the unknown side you are solving for and theta is the opposite angle to a. Since the angle opposite to R is supplementary to the 50 degree angle, 180-50=130. b could be assigned to either of the given sides; the same goes for c (e.g. b=40 and c=38). Thus, the question should be straightforward in plugging in quantities and solving for the resultant force.

ValentinkaMS [17]

Answer:

$H_o:\mu = 48\\H_a:\mu\neq48$

Step-by-step explanation:

Given : . The manufacturer of a refrigerator system for beer kegs produces refrigerators that are supposed to maintain a true mean temperature, 48°F, ideal for a certain type of German pilsner.

To Find : The owner of the brewery does not agree with the refrigerator manufacturer, and claims he can prove that the true mean temperature is incorrect.

Solution:

We are given that refrigerators that are supposed to maintain a true mean temperature, 48°F.

Claim : The true mean temperature is incorrect.

So, null hypothesis and alternate hypothesis will be :

$H_o:\mu = 48\\H_a:\mu\neq48$

So, Option D is true .

Is 6 pints equal to less than or more than 60 fluid ounces

Vinil7 [7]

The answer is 6 pints equal to more than 60 fluid ounces

1 pint = 16 ounces.
6 pints = x

Use the proportion:
1 pint : 16 ounces = 6 pints : x
x = 16 ounces * 6 pints : 1 pint
x = 96 ounces

6 pints = 96 ounces > 60 ounces
Therefore, 6<span> pints equal to more than 60 fluid ounces</span>
