PLEASE HELP, THIS MY LAST QUESTION. I WILL MARK BRAINLEST.
dalvyx [7]

Answer:

Part 1: 30.35 runners

Part 2: 2024

Step-by-step explanation:

We will need to find an equation that best fits this data

  • The equation of best fit for this data is y = 2.16x - 4291.81

Now in order to figure our part 1, we will need to plug in 2001 for our x value to solve for y and we get:

  • y = 2.16(2001) - 4291.81 which then simplifies to y = 30.35

Then to figure out part 2, we need to plug in 80 (NOT 80,000 because the y-values are in thousands, meaning we only need to use the number 80) for our y-value and solve for x and we get:

  • 80 = 2.16x - 4291.81
  • Adding 4291.81 to both sides we get: 4371.81 = 2.16x
  • Then dividing both side by 2.16 we get 2023.98 = x ≈2024

Triangle ABC is shown below.
Nimfa-mama [501]

The <em><u>correct answer</u></em> (though it is not one of the choices) is:

Alternate Interior Angles Theorem.

Explanation:

Alternate interior angles are angles that are inside the parallel lines and on opposite sides of the transversal.  Treating BA as a transversal, ∠DBA and ∠BAC are both inside the parallel lines and on opposite sides of BA, the transversal.  This makes them alternate interior angles, and means that they are congruent.
