The left and right page numbers of an open book are two consecutive integers whose sum is 293.  Find these page numbers.
sesenic [268]

Since they are consecutive, we can define the two unknowns with ease.

The left page (has a smaller value) can be defined as X, and the right page can be defined as X+1.

So,

X + (X+1) = 293

2x+1 = 293

2x = 292

x = 146

So, as we defined before, the smaller page number is equal to x.  Therefore, the smaller page number is 146, and the larger page number is 147.

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
