Answer:
The number of trials recorded during the experiment is 18.
Step-by-step explanation:
The given dot plot, the dots represents the time trials of an experiment. Each number on the dot plot represents the amount of time, in seconds, it took to complete a trial.
Time dots
15 2
16 0
17 3
18 0
19 2
20 2
21 1
22 0
23 4
24 1
25 3
Total 18
Therefore the number of trials recorded during the experiment is 18.
The number of time trials recorded during the experiment is [tex]\boxed{18}.[/tex]

Explanation:
Dot plot is a chart in which frequency and the number can be expressed by a line and the data is represented by the dot.
It is a simple type of histogram. It can only be used for discrete numbers.
In dot plot or line plot the data points are plotted as dots along with the line.
From the dot plot is has been observed that are 18 dots on the graph means that there are 18 number of trials and the data range between 15 and 25.
The time and the number of trials are as follows,
Time 15 has 2 dots.
Time 16 has no dot.
Time 17 has 3 dots.
Time 18 has 0 dots.
Time 19 has 2 dots.
Time 20 has 2 dots.
Time 21 has 1 dot.
Time 22 has 0 dots.
Time 23 has 4 dots.
Time 24 has 1 dot.
Time 25 has 3 dots.
Total number of trials can be calculated as follows,
[tex]\begin{aligned}{\text{Total trials}} &= 2 + 0 + 3 + 0 + 2 + 2 + 1 + 0 + 4 + 1 + 3\\&= 18\\\end{aligned}[/tex]
The number of time trials recorded during the experiment is [tex]\boxed{18}.[/tex]
