Answer:

Option D) shows quadratic variation.    

Step-by-step explanation:

We are given the following information in the question:

  • Variation refers to a relationship between two variables.
  • There are a number of different types of variation, such as direct variation or inverse variation.
  • Quadratic variation to describe a  way in which two variables relate to one another.
  • We could write quadratic variation as:

y = kx^2, where k is a constant.

Option D) is an example of quadratic variation and can be explained as:

For k = 3

y(x) = 3x^2\\\\x = 1\\y(1) = 3(1)^2 = 3\\\\x = 2\\y(2) = 3(2)^2 = 12\\\\x = 3\\y(3) = 3(3)^2 = 27\\\\x = 4\\y(4) = 3(4)^2 = 48

Hence, Option D) shows a relation of quadratic variation.

The ratio of in-state to out-of-state visitors to the amusement park was 4 to 3. If there were 14,000 visitors to the park, how
exis [7]

Answer:

<em>6000 people</em>

Step-by-step explanation:

Given the ratio of in-state to out-of-state visitors to the amusement park was 4 to 3, the total ratio will be 4+3 = 7

Total visitors in the park = 14,000 visitors

Number of people that were out of state = 3/7 * 14000

Number of people that were out of state = 3 * 2000

Number of people that were out of state = 6000

<em>Hence there were 6000 people out of state.</em>

What would be the answer?
zmey [24]

Answer:

6

Step-by-step explanation:

To breakeven means that you made exactly as much money as you spent, so if you spent $50 to make lemonade, you would need to make $50 in profits from selling to break even

first subtract the cost of making each horse from the price of selling each horse (you do this to find out how much profits he makes from one horse):

125 - 75 = 50

now divide 300 by 50 to find out how many horses need to be made to break even:

300 ÷ 50 = 6

Answer:

The answer is ratio Level of measurement

Step-by-step explanation:

It is important that I explain the various levels of measurement. There are four levels of measurement;  nominal, ordinal, interval and ratio levels of measurement.

1. Nominal Level of Measurement;  The nominal scale or level of measurement simply names or categorizes responses. examples are categorizing entries into religion, gender, hair color, etc. It is the lowest scale of measurement and they do not imply ordering among the group example, in classifying hair color, there is no numerical ordering value or red being more than black.

2. Ordinal Level of Measurement; Ordinal scale allows for comparison between two subjects to the degree of which they posses the dependent variable. For example, a researcher wanting to determine the level of satisfaction of customers to a product can group the customers from most dissatisfied to most satisfied.

3. Interval Level of Measurement; here, the level of measurement are numerical and they have the same distance (degree of difference) throughout. In the interval level of measurement, there is no true zero point on the scale, but the distance between two sets of points can have the same interval, but it will be irrational to make ratio comparisons. example is the Fahrenheit scale for temperature measurement, there is no true zero point, but a temperature difference between 20° F and 30° F is the same as the difference between 50° F and 60° F.

4. Ratio Level of Measurement; This is the most detailed level of measurement, and in addition to the interval scale, there is a true zero point. Mathematical computations can be carried out on them. It can be said to be the other three levels of measurement summed up in one. For example, money can be measured on the ratio scale because there is a zero point and it is mathematically accurate to say that 20 cents is twice as much as 10 cents. In our example, the survey is on eye color which ordinarily would have been on the nominal or categorical scale of measurement, but for the fact that the number of people possessing a quality is counted, it makes it ratio, and mean value was even calculated to be 1.5. There is a possibility of having a particular group of eye color with no participant, hence the zero point.
