To solve this problem you must apply the proccedure shown below:

 1- You must rewrite each value shown in the picture attached, in decimal form, as following:

 6π-6=12.84
 π^3=31
 √99=9.94

 2- Now, you can order the values from least to greatest:

 √99
 6π-6
 π^3

 The answer is:

 √99
 6π-6

The regression equation which correctly models the data in this table is y = 1.49x - 107.5,

<h3>How to determine the regression equation?</h3>

From the table of data values, we have the following parameters:

∑x = 632

∑y = 404

∑x² = 80.142

∑xy = 51.448

Mathematically, the regression equation is represented by the following slope equation:

y = Bx + A

Next, we would determine A by using this expression:

A = (∑y·∑x² - ∑x·∑xy)/(n∑x² - (∑x)²)

A = (404×80,142 - 632×51,448)/(5×∑x² - (632)²)

A = (32,377,368 - 32,515136)/(5×80142 - 399,424)

A = -137,768/1286

A = 107.5

For B, we have:

B = (n∑xy· - ∑x·∑y)/(n∑x² - (∑x)²)

B = (5×51,448 - 632×404)/(5×∑x² - (632)²)

B = 1.49.

y = Bx + A

y = 1.49x - 107.5

a caravan crossed 1378 miles of desert in 85 days it traveled 22 miles the first day and 28 the second day if caravan traveled t
Ronch [10]
Dist. travelled for the first 2 days
= 22 + 28
= 50

Dist. travelled for the remaining 83 days
= 1378 - 50
= 1328

Dist. travelled for EACH of the 83 days
= 1328 ÷ 83
= 16
