Answer:

12

Step-by-step explanation:

If you draw a line through each dots, one being from (2,3) to (8,15) and the other being (2,2) to (9,9). And, then if you draw one that is roughly halfway between the two of the first starting points with a slope of 1.5(which is the other 2 lines slopes combined and divided by two to find an average), and then draw out that line to x=9, you will see that it intersects with 13, which is 1 away from 12. Making it the one closest to the line of best fit

A triangular pyramid is formed from three right triangles as shown below.
Bess [88]

Answer:

  FH = 108

Step-by-step explanation:

The given figure requires we use the Pythagorean theorem to write two relations involving right triangle side lengths. The Pythagorean theorem tells us the square of the hypotenuse is the sum of the squares of the other two sides.

__

<h3>Triangle EGH:</h3>

  EG² = GH² +HE²

  GH² = EG² -HE² = 53² -28² = 2025 . . . . . solve for GH², use given values

<h3>Triangle FGH:</h3>

  FG² = GH² +FH²

  FH² = FG² -GH² = 117² -2025 = 11664 . . . . solve for FH², use known values

  FH = √11664 = 108 . . . . . take the square root

The length FH is 108.

7/10 x 6/9 x 5/8 = 21/100 or 0.21
