The correct answer: 01:12 A.M. OR 13:12 P.M.
First, decompose 30, 18 + 12 = 30.
Since 12:42 Minutes + 18 Minutes
is equal to 13:00, then add the remaining 12 Minutes, completing a total of 01:12 a.m. OR 13:12 P.M.

and 
respectively.
Step-by-step explanation:
Consider the provided information.
If there is no statistical significance in the test then it is know as the null which is denoted by 
, otherwise it is known as alternative hypothesis which denoted by 
.
Consider the statement:
Test to see whether the mean tree planting time differ from two hours.
The null hypothesis is:
Therefore, the alternative hypothesis is:
Thus, the null and alternative hypothesis is and respectively.
Answer:
320 in.²
Step-by-step explanation:
Let's think of the shape as a normal rectangle with a height of 16 inches. Now all we need is the length. If you look at the right corner, it looks like a piece has been cut out. Since that piece has the same length and height of 8 inches, it is a square. This tells us the missing length of the entire length of the rectangle. Now the length of the rectangle is 16 inches + 8 inches, which is 24 inches.
The total area of the rectangle is 16 × 24, which is 384.
Then from the total area, we just need to subtract the area of the cut-out part. The area of the cut-out square is 8 × 8, which is 64.
384 - 64 = 320
The total surface area of the following complex shape is 320 in.²
6x^5 - 5x^4 + 6x^3 - x^2 + 12x - 31
