Archie is fed up with waiting in line at his local post office and decides to take action. Over the course of the next few
1 answer:
The proportion of waiting times in the sample that are greater than or equal to 18 minutes is 0.16.
<h3>What is a histogram?</h3>
A histogram is used to represent data graphically. The histogram is made up of rectangles whose area is equal to the frequency of the data and whose width is equal to the class interval.
Number of people whose wait time was equal or greater than 18 minutes / total number of people = (2 + 2) / (6 + 7 + 8 + 2 + 2)
4/25 = 0.16

When we multiply together numbers with the same base,
we add the exponents.
When we divide numbers with the same base, we
subtract the exponents.
If we have a fraction to a power, we raise the numerator and
the denominator to that power.
And then last but not least,
If we have a number with a negative exponent, we flip it over.

<h2>Explanation:</h2><h2></h2>
The complete question is in the attached file. So we have to choose between two graphs. On of them is a linear model while the other is an exponential model. From the statements, we have a relationship between time and the number of teams registered. So we can establishes variables in the following form:
We also know that each week 6 teams register to participate, so:
As you can see, as x increases one week, y increases at a constant ratio of 6. Therefore, this can be modeled by a linear function given by the form:
In conclusion, <em>the linear model (first graph below) is the one that bests represents the relationship between time and the number of teams registered.</em>
