What is the difference between an observational study and an experiment
Blizzard [7]

Answer: In observational study observer has no control on the variables but in an experiment experimenter has control over the independent variable to record the change on the dependent variable.

Step-by-step explanation:

In statistics , an observational study is a study in which a researcher just observe effects on subjects in a certain manner without interfering them.

On the other hand an experiment is a process which is done by experimenter to  demonstrate a known fact or create a discovery by applying some methods to the variables  .

A group 6 students was asked, how many hours did you watch television last wee? Here are their responses. 20, 5, 7, 17, 16, 15,
Sindrei [870]

Answer:

13.3

Step-by-step explanation:

There is an equation that helps

mean= (All of the numbers in the data added) divided by (the number of numbers in the data)

What that mean is:

1.) Add 20, 5, 7, 17, 16, and 15

2.) divided by 6 (because there is 6 numbers in the data)

3.) round it to the nearest number (numbers from the one's place being 4-0 means go back or 5-9 means go forward a number)

which in this case it should be 13.33333...=13.3

The volume of a prism with side lengths measured in millimeters is 20. How could this measurement be written? Check all that app
Katyanochek1 [597]

The unit measurement of the a volume in mm is mm³(millimetres cube.)

<h3>How to find volume ?</h3>

Volume is is defined as the space occupied within the boundaries. The objects are usually solid objects.

The volume of a 3 dimensional figure is the product of the base area and the height.

Therefore, the units of volume is measured in cubic units.

The volume of a prism with side lengths measured in millimetres is 20.

Therefore, the measurement can be represented as follows:

20 mm³

Is this a discrete or continuous function? Explain.
faust18 [17]

A graph with points (-5, -2), (1, 5), and (-5, 5) represents a discrete function.

<h3>What is a graph?</h3>

A graph can be defined as a type of chart that's commonly used to graphically represent data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-axis and y-axis.

<h3>What is a discrete function?</h3>

A discrete function can be defined as a type of function in which the ordered pair of values on the x-axis and y-axis are separate from each other and unconnected.

In conclusion, the function which this graph represents is a discrete function because both the domain (-5, 1) and range (-2, 5) have discrete set of values, rather than intervals.
