Answer:

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 :

So, Option D is true .
Correct answer for the above question is - option B. 86°
<u>Step-by-step explanation:</u>
Given:
∠NOP = 24°
∠NOQ = 110°
∠NOP and ∠POQ are adjacent angles
To Find:
∠POQ = ?
Solution:
Hereby, we can say that ∠POQ lies between line OQ and ON as given (∠NOP and ∠POQ are adjacent angles )
∠NOQ - ∠NOP = ∠POQ
∠POQ = 110° - 24°
<u>∠POQ = 86°</u>
Angle POQ is 86°
Thus we can conclude option B as correct answer.
Answer:
P' = (7, - 8)
Step-by-step explanation:
Under the given translation (x + 4, y - 3)
Add 4 to the x- coordinate of P and subtract 3 from the y- coordinate of P
P' = (3 + 4, - 5 - 3 ) = (7, - 8)

Step-by-step explanation:
Answer: 80°
Step-by-step explanation:
The sum of the angles in a triangle is 180°. Since the two angles of a triangle measure 15° and 85°.
The measure for the third angle will be:
= 180° - (15° + 85°)
= 180° - 100°
= 80°
The third angle is 80°
