Recall that the area under a probability curve is always 1.0. Here we have a probability distribution from 10.6 to 18.6 minutes, of length 10 minutes, so the height of the probability "curve" is 1.0 / 10, or 0.1.

To answer this question, find the area under the probability "curve" between 13.8 and 16.8 minutes. The difference between 13.8 and 16.8 is 3 units, so the desired probability is 3(0.1), or 0.30.

Select from the drop - down menus to correctly complete each statement
Stels [109]

In a flowchart proof, <u>statements</u> and <u>conclusions</u> are connected with arrows.

In terms of mathematics, a statement is simply any sentence in which it can be verifiably true or false. A statement cannot be a subjective opinion. It must be an objective fact and there must not be any ambiguity involved. A conclusion is also a statement that derives from the first statement made.

As an example, you can have the simple argument "if it rains, then it gets wet outside". So the box on the left would be "it rains" and the box on the right would be "it gets wet outside". An arrow connecting the two shows the logical flow of how the argument is set up.

See the diagram below.

Side note: the box on the left is also considered the antecedent because it comes before the conclusion.

Answer:

18.7 m/h

Step-by-step explanation:

I believe that is the correct answer because it shows the answer is going to be m/h (meter/hour) so then you would just divide the meters over the hours.

768.57 / 41.1 = 18.7 m/h
