Step-by-step explanation:
If we assume that the matrix is populated with (difference of high temperatures) in the first row and (difference of low temperatures) in the second row, we only need to look for one value.
The difference between the Monday high temperatures is 35 - 26 = 9 degrees. We expect that to be in the first row of the first column of the matrix we're looking for. We find that matrix in selection D.
If

, then by the remainder theorem

has a remainder of 0, which means

is divisible by

. In fact,

So we know 1 is a root, and the other two roots are -1 and -3.

Answer:
95% Confidence interval: (0.375,0.377)
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= 0.376 cc/cubic meter
Sample size, n = 15
Alpha, α = 0.05
Sample standard deviation, s = 0.0012
Degree of freedom =

95% Confidence interval:
Putting the values, we get,
(0.375,0.377) is the required 95% confidence interval for the population mean potassium chloride concentration.
