Answer:
1. Nominal
2. Interval
3. Interval
4. Nominal.
Step-by-step explanation:
Nominal scales are used when the variable we're interested in has NO quantitative value.
Therefore, the college you are enrolled in and your hometown are examples of nominal data.
Interval scales are used when the variable we are interested in has quantitative value and the values have an order and the difference between each value is the same.
For the case of number of students, we know, for example, that 20 students < 21 students, and the difference between 20 and 21 is the same as the one between 21 and 22. The same applies for the age of your classmates.
Therefore, the age of your classmates and the number of students in a statistics course is an interval data.
Yes this is proportional!
To start, this is an interest problem, meaning you will have to use I=prt where I is the total interest, p is the principle amount, r is the rate, and time is the amount of time in years. Since you know the principle rate is $1200, the rate is 3.9%, and the time is 8 months, you can plug this into the formula. However, keep in mind that you have to convert 3.9% to a decimal before putting it into the formula and the time must be represented in years. 3.9% represented as a decimal would be 0.039 and 8 months would be represented as 8/12 or 2/3 (since there are 12 months in one year). Now that you have this information, plug the values into the formula: i=(1200)(0.039)(2/3). When simplified, you get your answer as $31.20.
Answer:
40 cups
Step-by-step explanation:
We need to convert from quarts to cups using a conversion factor
We know that 1 quart = 4 cups
10 quarts * 4 cups
----------- = 40 cups
1 quart
The equation cos (35°) = can be used to find the length of one side of a triangle It could be the length of the altitude or the length of the base depending of which the angle 35° was assigned. But in order for us to proceed with the calculation, we also need the length of the hypotenuse since cos (x) are<span> equal to the length of the adjacent side divided by the hypotenuse. The answer is 20.5 </span>
