Between 3 and 4 cups.
Let’s find 87% of 4.
(4)(0.87)= 3.48
So in 4 cups of milk, there is 3.48 cups of water, which is between 3 and 4 cups.
Week 1=1
week 2= 3
week 3= 9
week 4= 27
week 5= 81 pots
81 pots is the answer

<u>Answer</u>
−1 + i times the square root of 7
<u>Explanation</u>
x² + 2x + 8
I will use the complete square method to find the value of x.
x² + 2x + 8
x² + 2x = -8
x² + 2x + (2/2)² = -8 + (2/2)²
x² + 2x + 1 = -7
(x + 1)² = -7
x + 1 = √(-7)
x = √(-7) - 1
= i√7 - 1
= -1 + i√7
<em>−1 + i times the square root of 7
</em>
Answer:
B. 97
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
How many students should be sampled to be within 1 drink of the population mean with 95% probability?
This is n when 
We know from preliminary studies that the standard deviation is around 5, so 
We round up, so the correct answer is:
B. 97
