Answer:
E
Step-by-step explanation:
Since 0 is in confidence interval, and negative and positive values are also, we are 96% confident in all possible answers in this interval so since true slope could be negative or positive in our interval, we cannot determine it
The half life of the substance is 6.92 days.
<h3>What is the Half life ?</h3>
Half life can be defined as the time required to reduce the concentration to half of its initial value.
Here the equation given is
The concentration will reduce to half therefore
so,
ln 0.5 = - 0.1001 * t(1/2)
-0.693 = -.1001 * t(1/2)
t(1/2) = 6.92 days.
Therefore the half life of the substance is 6.92 days.

- All the listed combination of row and boxes are correct and can be chosen from.
From the question, we are asked to find the row arrangement of a stack of boxes. Let us take a look at each one of the aforelisted answers
- x rows with 16 boxes in each row
- 8 rows with x boxes in each row
- 16 rows with x boxes in each row
Since we are told that the total number of boxes to be stacked is 64, then for the first arrangement, we can deduce that the "x" is going to be 4. This is because multiplying 4 by 16 gives 64. For the second row, using the same calculation, we find that "x" is 8. And that of the third gives our "x" to be 4 as well. We can then adjudge that;
- 4 rows with 16 boxes in each row
- 8 rows with 8 boxes in each row
- 16 rows with 8 boxes in each row
Bearing this in mind, we can see that each of the 3 answers fits into the requirements we are asked.
- At least 3 rows, and at least 4 boxes in each row.
Hence, all of the options are correct.
