Answer:

P = 5.3x = 206,700

Step-by-step explanation:

P = population

P = 5.3x, where x is the square miles

p = 5.3(39000) = 206,700

Answer:

1024pi/3

Step-by-step explanation:

to find the volume of a sphere you use the equation 4/3*pi*r^3

4/3*pi*8^3

4/3*pi*512

2048/3 pi

This is the volume of the whole sphere but we only need half so we can just divide by 2.

(2048/3 pi)/2

1024/3 pi

A group of 20 children were asked their age and how many pages they read in a week. The scatter plot shows the data.
vovangra [49]
The outlier would be the one with (17, 72) coordinates. If interpreted, the child is 17 years old and the number of pages the child reads in a week is 72. He appeared the outlier because his data was too far from the pattern of data relative to the sample.

jennifer bikes 7 miles south and then turns to bike 13 miles east how far away is she from where she started?
Marina CMI [18]

Answer:

She is about 14.765 miles (\sqrt{218} miles) from where she started

Step-by-step explanation:

There is a relation between the three sides of the right triangle

  • The side opposite to the right angle is called hypotenuse and it is the longest side
  • The other two sides called legs of the right angle
  • The relation between them is: (hypotenuse)² = (leg1)² + (leg2)²

∵ Jennifer bikes 7 miles south

∵ She turns to bike 13 miles east

∵ South and East are perpendicular

→ That means the distance from her start point to end point represents

   a hypotenuse of a right triangle, whose legs are 7 and 13

∴  (hypotenuse)² =  (leg1)² + (leg2)², where

  • hypotenuse is the distance between her start and end points
  • leg1 is her distance in south direction
  • leg2 is her distance in east direction

∵ Leg1 = 7 miles

∵ leg 2 = 13 miles

∴ (hypotenuse)² =  (7)² + (13)²

∴ (hypotenuse)² = 49 + 169

∴ (hypotenuse)² = 218

→ Take √  for both sides

∴ hypotenuse = \sqrt{218}

∴ hypotenuse ≅ 14.76482306

∴ She is about 14.765 miles (\sqrt{218} miles) from where she started.
