Answer:

1. The type of charge card used by a customer (Visa, MasterCard, AmEx)? Nominal

2. The duration a flight from Boston to Minneapolis? Continuous Ratio

3. The number of Nobel Prize-winning faculty at Oxnard University? Discrete Ratio

4. Temperature in degrees Celsius at 7 o'clock this morning? Continuous Interval

Step-by-step explanation:

1. Nominal data deals with the classification of items based on their names or labels. They are qualitative in nature. The type of charge card used by a customer is an example.

2. Continuous data are quantitative data that can appear in decimal forms. They are obtained by measurement.

3. Discrete data is also quantitative data that cannot be divided. They appear as whole numbers.

4. Interval data has the same difference between the variables. They do not have a true zero. For example, there is nothing like 0 degree Celsius. Ratio data on the other hand is interval data with a true zero.

Use the formula for the volume of a cylinder to find the volume of a water tank (in ft with a radius of 15 feet and a height of
alex41 [277]
Answer: See below

Explanation:

Formula: V = pi x r^2 x h

Pi = 22/7
r = 15 ft
h = 35 ft

=> V = 22/7 x 35 x 15^2
=> V = 22 x 5 x 15^2
=> V = 110 x 225
=> V = 24,750 ft^2

a) First, draw a graph. The x axis should be numbered: 0, 1, 2, 3, 4, 5, 6, 7, 8. Each number is the last digit of the year. For each year, there is one average score that has to be plotted. Number the y axis of the graph from 0-600, by increments of 50, or something around there. Now, with each year (each x value) place the dot as high as the average score. Repeat with all years. DO NOT draw a line to connect them. A scatter plot is a bunch of points that are not connected.

b) Use the form (y2-y1)/(x2-x1) where (x1,y1) (x2,y2) are any two points from 2001-2006. It does not matter which points, pick any, and assign each of the numbers x1,y1 and x2,y2. Plug it in to the equation, and simplify. This is your slope, also called m. Now plug m into the equation y-y1=m(x-x1) where y1 and x1 are the x and y coordinates of any point from 2001 to 2006. x and y dont have values themselves, they stay there. Now distribute the m into the parenthesis, add y1 to both sides (to cancel it out on the left), and you should be left with the same equation, but now in y=mx+b form. B is where the line crosses the y axis, so put a point on the vertical axis where b is. M is your slope, so every time you go to the right one number, go up M numbers. Draw another point. Repeat this until you can connect these new dots into a line. This line should be on the same graph as your other points, but might not touch all of the scatter plot points. That's still okay, just leave it as is.

c) Find the point where x=6 (meaning the year is 2006) on your line. Find the average test score for that year by seeing where the point lines up along the y axis (draw a straight line from the point to the left to see, if you have to). Take that number and add 1m (the m is the number you used in step B) to it. This predicts what the average score might be after 1 (that's why the 1 is there) year. This is a predicted value, and might not be perfectly correct!! Write/record how close this new, predicted, score is to the actual number, 515, which can be found on the scatter plot.

d) repeat step C exactly as before (still use the year 2006) , but add 4m instead of 1m, to get the predicted score 4 years after 2006 (2010), instead of 1 year after (2007).

I hope I have been of some help! Best of luck!!! :)
