Answer:

  • a negative correlation between the temperature and the amount of snow still on the ground
  • a negative correlation between the number of digital photos uploaded to a website and the amount of storage space that is left

Step-by-step explanation:

1. A negative correlation between the temperature and the amount of snow still on the ground


This is casual since temperature and amount of snow are inversely proportional to each other.

2. A negative correlation between the number of digital photos uploaded to a website and the amount of storage space that is left


This is casual since the number of digital photos uploaded and the amount of storage space are  inversely proportional to each other.

3. A positive correlation between the length of the side of a pool and its depth

.

This is not casual since the length of the side of a pool and its depth  are not related.

4. A positive correlation between the height of a woman and the height of her brother

.

This is not casual since the height of a woman and the height of her brother  are not related.

5. A negative correlation between the volume of water in a pot and the amount of time that the water takes to boil

This is not casual since the volume of water in a pot and the amount of time that the water takes to boil are directly proportional.

What is the area of triangle BCD to the nearest tenth of a square centimeter? Use special right triangles to help find the heigh
tatiyna

Answer:

Area = 21.7 cm² (nearest tenth)

Step-by-step explanation:

A 30-60-90 triangle is a special right triangle.  The measures of its sides have a special relationship in that they are in proportion:

shortest leg : longest leg : hypotenuse =  1 : √3 : 2

  • The side opposite 30° is the shortest leg
  • The side opposite 60° is the longest leg and is √3 times the length of the shorter leg.
  • The side opposite 90° is the hypotenuse and is twice the length of the shorter leg.

So we can also write the ratio as  x : x\sqrt{3} : 2x  where x is the shortest side.

From inspection of the diagram, the shortest side is 5 cm

⇒ BC (height) = 5 × √3 = 5√3 cm

Now we have the height, we can calculate the area.

Area of a triangle = 1/2 x base x height

                             = 1/2 x 5 x 5√3

                             = 21.7 cm² (nearest tenth)
