Answer:
The right answer is Option D:
Step-by-step explanation:
Given that initial value of 3/2 and rate of change is -2/3
The given functions can be observed and it can be concluded that the functions are in the form
Here m is the slope which is also called rate of change and c is the y-intercept.
The y-intercept is the initial value when input is zero.
So we have to look for a function that has 3/2 in place of c and -2/3 in place of m.
From the given options,
is the matching function
Hence,
The right answer is Option D:
Create a frequency chart by using a bar graph as shown in the picture below. A frequency chart is used when you want to present how much of the data belongs to one group. For this problem, it specifically represents how many people belong to a time interval. The y-axis is the number of people and the x-axis is the time expressed in intervals.
As you can see visually, the shape of the distribution graph is skewed to the right, although not uniformly. This is justified because the relatively high data are situated on the far right side of the graph. Also, there are no outliers in the data because they are all pretty close to each other. No bar is obviously different from the others. The center is the median of all the data. If you create a middle line as represented by the horizontal line, the center data point is 21. You can verify this by arranging all the data points from smallest to largest, and selecting the middle data. Lastly, the spread is from the lowest value to the highest value. The lowest value is at 12 to 1 pm with 19 people. The highest value is at 4 to 5 pm with 24 people. Therefore, the spread is from 19 to 24.
