Find A. Round to the nearest tenth.

Marianna [84]

Answer:

27.8 degrees

Step-by-step explanation:

Wasn't it 'a,' not 'A,' that you wanted?

The ratio a/ 30 is the cosine of the angle 22 degrees, which in turn is 0.927:

a

Then 0.927 = ------- which yields a = 30(0.927) = 27.8 degrees

Your height and weight are examples of which level of measurement? A. Ordinal B. Nominal C. Ratio D. Interval

Ivahew [28]

Answer:

C. Ratio

True for this case we have a clear definition of the 0 since the 0 for the heigth and the weigth represent absence of mass. And the differences between numerical values for the two variables are meaingful.

Step-by-step explanation:

We want to know which type of variable represent the weigth and the height. Let's analyze one by one the options given:

A. Ordinal

False since by definition an ordinal variable is "is a categorical variable for which the possible values are ordered". And for this case the height and the weigth are not categorical since represent quantitative data.

B. Nominal

False by definition and ordinal variable is which one that can't be represented by numeric values, and for this case the weight and the height are not example of this definition.

C. Ratio

True for this case we have a clear definition of the 0 since the 0 for the heigth and the weigth represent absence of mass. And the differences between numerical values for the two variables are meaingful.

D. Interval

False on this scale we don't have a clear definition of the 0. And for this case the heigth and the weight have a known definition of the 0 corresponding to the absence of mass. And since the ratios are meaingful for the heigth and the weigth then can't be an interval variable.
