Sorry I'm late but the answer is 1/2. I just took the quiz and I got 100%
Question:
What is the independent quantity, and which variable should represent it?
Answer:
They're independent of everything else. The dependent variable (sometimes known as the responding variable) is what is being studied and measured in the experiment. It's what changes as a result of the changes to the independent variable. An example of a dependent variable is how tall you are at different ages.
Explanation:
The two main variables in an experiment are the independent and dependent variable. An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment. The dependent variable is the one that depends on the value of some other number. ... Another way to put it is the dependent variable is the output value and the independent variable is the input value. So for y=x+3, when you input x=2, the output is y = 5. An experiment usually has three kinds of variables: independent, dependent, and controlled. The independent variable is the one that is changed by the scientist. Independent variable – the variable that is altered during a scientific experiment. Dependent variable – the variable being tested or measured during a scientific experiment. Controlled variable – a variable that is kept the same during a scientific experiment.
Note:
Sorry i'm 5 days Late, But i hope this clears up any confusion for anyone!
Answer:
2h and a half
Step-by-step explanation:
2h and a half
60+60=2h
30= half of 60 so
2.5
Using the given table, it is found that the mean number of children per household for these families is of 2.33.
<h3>What is the mean?</h3>
The mean of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.
Researching the problem on the internet, the table states that:
- 2 households have 4 children.
- 16 households have 2 children.
- 13 households have 3 children.
- 5 households have 1 children.
The total number of children is given by:
T = 2 x 4 + 16 x 2 + 13 x 3 + 5 x 1 = 84
Hence the mean number of children for the 36 households is given by:
M = 84/36 = 2.33.
