Determine which of the four levels of measurement (nominal, ordinal, interval, ratio) is most appropriate for the data below. brain volumes measured in cubic cmbrain volumes measured in cubic cm

The ratio level of measurement is most appropriate because the data can be ordered differences can be found and are meaningful, and there is a natural starting zero point.

That's the correct answer since our variable is numerical and have a natural starting point at 0 and the negative values not makes sense.

Step-by-step explanation:

The interval level of measurement is most appropriate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting point.

Our variable is numerical but we have a starting point defined so it can't be an interval variable.

The nominal level of measurement is most appropriate because the data cannot be ordered.

False on this case the bolume can't be a nominal variable since we don't have a categorical variable.

The ordinal level of measurement is most appropriate because the data can be ordered, but differences (obtained by subtraction) cannot be found or are meaningless.

False we don't have ordered relationship among the variable’s observations

The ratio level of measurement is most appropriate because the data can be ordered differences can be found and are meaningful, and there is a natural starting zero point.

That's the correct answer since our variable is numerical and have a natural starting point at 0 and the negative values not makes sense.

m∠cdf = 43° , m∠gdf = 114°, m∠gde = 23°, m∠edh = 23° , m∠cdh = 157°

step-by-step explanation:

since, it is given that de bisects the angle gdh ⇒ de divides the angle gdh into two equal angles.

⇒ m∠gde = m∠edh

⇒ 8·x   - 1 = 6·x + 5

⇒ x = 3

so, m∠gde = 8·x - 1 = 23°

and m∠edh = 23°

now, it is given ∠cde is an straight angle so, m∠cde = 180°

⇒ m∠cdf + m∠fdg + m∠gde = 180°

⇒ 43° + m∠fdg + 23° = 180°

⇒ m∠fdg = 114°

again, m∠cde = m∠cdh + m∠edh = 180°

m∠cdh + 23° = 180°

⇒ m∠cdh = 157°
