In the year 2000, the average cost of a computer could be modeled by the equation C = -5t2 + 750, where t is the number of years
1 answer:
Answer:
Step-by-step explanation:
Given:
The average cost of a computer in the year 2000 is given as:
The average cost of a computer in the year 2008 is given as:
Now, the difference in average cost between the years 2008 and 2000 can be calculated by subtracting the average cost in 2000 from the average cost in 2008.
Framing in equation form, we get:
Difference in average cost (ΔC) is given as:
Therefore, the difference in the costs for a computer between 2008 and 2000 is

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.

Given, Shelby made 5 quarts of juice for a picnic.
We know that 1 quart of juice = 4 cups of juice.
Here we will have to convert 5 quarts to cups.
As for 1 quart there are 4 cups, to find 5 quarts we have to multiply 4 times 5.
So 5 quarts of juice = cups of juice.
We know that,
5 quarts of juice = 20 cups of juice.
We have got the required answer here.
Shelby made 20 cups of juice there in the picnic.
