Answer:

A - B = (0, 6)

or,

Considering

A = 9

B = 3

A - B = 6

I've taken this approach, but I don't know what solution is expected for this question. It seems to be open.

Step-by-step explanation:

So, we have two intervals. I will consider both as open.

A= (0, 9) and B = (6, 9)

Taking:

A - B = (0, 6)

Write as a fraction or as a mixed number in simplest form 0.02

Dvinal [7]

2/100, or 1/50, if you mix the numbers up, you’ll get 1/50 because you mixed it I believe, and 0.02 is in the hundredths place because 0.2 is 2/10, so 1/50 would pretty much be your answer, but keep the my both just to reinsure you get full credit!!

The table shows the average number of hours of daylight per day for the last four months of the year. a 2-column table with 4 ro

mina [271]

The correlation coefficient for the data in the table is A. –0.993

<h3>Calculations and Parameters:</h3>

Using this formula: $r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}}$

We would use x and y to represent the unknowns.

n = 4

We have,

∑x = 42,
∑y = 44.37 ,
∑xy = 461.3
∑x^2 = 446,
∑y^2 = 494

Putting these values in the formula $r = \frac{n(\sum xy)-(\sum x\sum y)}{\sqrt{n\sum x^2-(\sum x)^2}\sqrt{n\sum y^2-(\sum y)^2}}$ would bring the answer as. A. –0.993
