luda_lava [24]

Answer:

Theoretical probabilities are the long-run relative frequencies based on an experiment.

Step-by-step explanation:

Relative frequency or experimental probability is calculated from the number of times an event happens, divided by the total number of trials in an actual experiment.

With theoretical probability, you don't experiment. Instead, you use what you know about the situation to determine the probability of an event occurring.

Experimental probability approaches theoretical probability when the number of trials is extremely large.

Therefore, theoretical probabilities are the long-run relative frequencies based on an experiment.

A section of a boardwalk is made using 15 boards. Each board is 914914 inches wide. The total width of the section is 144 inches
xeze [42]


<span><span>15 times 9.25 = 138.75 inches.
That leaves

144-138.75 = 5.25 inches for spaces. 
Between the 15 boards are just 14 spaces, however.
So divide 5.25 by 14 and get
3/8" for each space.</span>

<span>Hi there,
14 boards each 9 1/4 inches wide.
14 x 9 1/4 = 138 3/4 inches
144 inches - 138 3/4 inches

= 5 1/4 inches
Spaces between 14 boards
= 13 spaces.
5 1/4 / 13 = 2/5 of an inch.
Hope this helps. :-)</span></span>
