The subtraction expression shows C. -4-9
Answer:
No it not W = 1.9
Step-by-step explanation:
Because from
9.5 = w/0.2
W = 9.5 x 0.2
W = 1.9
Answer:
(a) the dependent variable here are the Participants.
(b) the dependent variable is discrete.
(c) The scale measurement of measurement used is interval/ratio to measure the dependent variable.
(d) the independent variable is Vitamin C
(e) The research method being used is experimental.
Step-by-step explanation:
The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment.
Examples of continuous dependent variable may include costs, profits and sales.But some dependent variables are discrete – that is, they take on a relatively small number of integer values.
Interval scale and ratio scale are the two variable measurement scales where they define the attributes of the variables quantitatively.A ratio scale is a measurement scale which has more or less all the properties of an interval scale. Ratio data on this scale has measurable intervals.
Experimental research is a study that strictly adheres to a scientific research design. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared.
