Answer:

0 < x < 28

Step-by-step explanation:

If a triangle has 2 sides, with lengths 7 and 21, the third side must -

have a length longer than zero <u>and </u>less than (7+21) = 28

so if the 3rd side has length x, then

0 < x < 28

The gray is a sidewalk and the turquoise is grass. Both are squares. What is the area of the sidewalk?

The last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.

A few fundamental principles apply to density curves:

  • A density curve's area beneath it represents probability.
  • A density curve's area under it equals one.
  • Base x height in a uniform density curve equals one.
  • The likelihood that x = a will never occur.
  • The likelihood that x < a is the same as that of x ≤ a.

Following the rules above, we can see from graph B that the curve is above the horizontal axis. That shows that the probabilities are positive which is a necessity. Moreover, the area under the curve must also be 1. That is also satisfied.

Hence, the last statement "Graph B is a valid density curve because the curve is above the horizontal axis, and the area under the curve is 1." is the correct statement.
