By Pythagoras theorem
The dot plot below shows the number of dogs in neighborhood houses: A dot plot with integers 1 to 5 is shown. It is labeled Dogs
, and titled Dogs in Houses. There are 4 dots above 1, 3 dots above 2, 2 dots above 3, 1 dot above 4, and 1 dot above 5. Which of the following statements best describes the shape of the data? It is symmetric and has a peak at 1. It is symmetric and has a peak at 4. It is not symmetric and has a peak at 1. It is not symmetric and has a peak at 4.
2 answers:
Answer:
The correct statement is:
It is not symmetric and has a peak at 1.
Step-by-step explanation:
We may make a dot plot based on the given information.
The dot plot is attached to the answer.
We may clearly observe that the dot plot is not symmetric since, there is no such point such that the plot to its left and right are equal.
Also,the frequency corresponding to '1' is highest (i.e. there are 4 dots above 1)
Hence, the peak of the dot plot is at '1'.

<h2>Hello!</h2>
The answer is: The first graphic representation.
<h2>Why?</h2>We are given a quadratic equation, meaning that it could be two possible solutions for the exercise, however, we are talking about time, so we have to consider only the obtained positive values.
Let's make the equation equal to 0 in order to find the values of "t"
So, discarding the negative value, we can use the possitive value to find the correct graphic representation.
To find the correct graphic representation we must take into consideration the following:
- We must remember that the sign of the coefficient of the quadratic term (t^2) will define if the parabola opens downward or upward.
From the given quadratic (or parabola) equation we have:
So, since the coefficient of the quadratic term is negative, the parabola opens downward.
- Since we are looking for a graphic that represents the change in height over time, we need to look for a graphic that shows only positive values for the x-axis (time)
- We are looking for a parabola which y-axis intercept is equal to 150.
Therefore, the graphic representation of the quadratic function that models a ball's height over time is the first graphic representation.
