Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate. Voltage measurements of batteries: 1.5 V, 3 V, 4.5 V, 6 V, and 7.5 V Choose the correct answer below.

a. Ordinal
b. Interval
c. Ratio
d. Nominal

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.

i think it is c, not positive though

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
