Answer:

14.4222

Step-by-step explanation:

Distance between two points = √(x₂ – x₁)² + (y₂ – y₁)²

Distance between two points = √(6 – -2)² + (-5 – 7)²

√(6 – -2)² + (-5 – 7)²

√8² + (-12)²

√64 + 144

√208

Answer:

4\sqrt{13}

Step-by-step explanation:

Calculate the distance d using the distance formula

d = \sqrt{(x_{2}-x_{1 )^2+(y_{2}-y_{1})^2   }

with (x₁, y₁ ) = (- 2, 7) and (x₂, y₂ ) = (6, - 5)

d = \sqrt{(6-(-2))^2+(-5-7)^2}

   = \sqrt{6+2)^2+(-12)^2}

   = \sqrt{8^2+144}

   = \sqrt{64+144}

   = \sqrt{208}

   = \sqrt{16(13)}

   = 4\sqrt{13}

Answer:

Approximately 94% of theaters charge more than $10 to see the movie.

Step-by-step explanation:

Use a calculator with distribution functions such as normalcdf(

Here we have normalcdf(10,1000,11.80, 1.15) = 0.941

Approximately 94% of theaters charge more than $10 to see the movie.  This agrees with the last answer choice.
