Margot is looking at some information for the obstacle course she is interested in completing. The x-coordinate is the number of

the obstacle, while the y-coordinate is the average time to complete the obstacle, measured in minutes.
(1, 6.25), (2, 6.875), (3, 7.5625), (4, 8.31875)

Help Margot use an explicit formula to find the average time she will need for the 8th obstacle.

f(8) = 1.1(6.25)7; f(8) = 409782
f(8) = 6.25(1.1)7; f(8) = 12.179
f(8) = 1.1(6.25)8; f(8) = 2561137
f(8) = 6.25(1.1)8; f(8) = 13.397

Answer:  f(8) = 6.25(1.1)^7 ; f(8) = 12.179

Step-by-step explanation: (I got it right on the test)

(1, 6.25), (2, 6.875), (3, 7.5625), (4, 8.31875)

r= 1.1  

f(1) = 6.25 / starting number

1. Since it is multiplying each number by 1.1 it is using the Geometric Explicit Formula:

f(n)= f(1) x r ^n-1

f(8) = 6.25 x 1.1 ^(8-1)

f(8) = 6.25 x 1.1 ^7

f(8) = 6.25 x 1.9487171

f(8) = 12.179

mr Goodwill [35]

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.
