Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Voltage measurements
Helen [10]

Answer:

Ratio

Step-by-step explanation:

Voltage measurement of batteries involves ratio level of measurement because it has a significant zero i.e. zero voltage of the battery will mean no voltage. The mathematical operations of multiplication, division, addition and subtraction  are meaningful in ratio level of measurement. The mathematical operations of multiplication, division, addition and subtraction on voltage measurement of batteries are meaningful.

Thus, voltage measurement of batteries involves ratio level of measurement.

if it takes 10 minutes for 15 machines to make 5 widgets, how many minutes would it take 5 machines to make 15 widgets
pshichka [43]

The number of minutes it will take 5 machines to make 15 widgets is 90 minutes

Given that :

The time taken to make a widget is directly proportional to the number of widgets made and inversely proportional to the number of machines utilized.

Using the variation protocol defined :

Let :

n = number of widgets made

n = number of widgets made m = number of machines used

n = number of widgets made m = number of machines used t = time taken

Hence, from joint variation :

t α n α 1/m

t = kn/m

Where k = constant of proportionality :

Solving for k

When t = 10, n = 5, m = 15

10 = (k × 5) / 15

15 × 10 = 5k

150 = 5k

k = 150 / 5

k = 30

Equation becomes :

t = 30n/m

Solve for t ;

When m = 5 ; n = 15

t = (30 × 15) / 5

5t = 450

t = 450 / 5

t = 90

Hence, it will take 90 minutes.
