Answer:
Internal validity
Step-by-step explanation:
Internal validity is a scientific study that emphasize on the fact that there is a proof to validate a specific study. Let's say i'm a forensics scientist for example; and there was a recent crime scene in some nearby sub-urban area which demands our call, when present at the scene, The main task there is to gather information as much as we can which is required to be investigate in the laboratory for further analysis.The process of information gathering is our independent variables which varies with different causes of the crime, the laboratory analysis that make deductions (which is cause by some manipulation) of the information gathered is our dependent variables.
Therefore, we can conclude that Internal validity refers to the degree to which changes in the dependent variable are due to the manipulation of the independent variable.
The formula of the perimeter of a rectangle is equal to:
Perimeter = 2L + 2W
Forming the equation.
<span>Perimeter = 2L + 2W
</span>17.6 = 2L + 2W
Getting the lengths.
<span>17.6 = 2L + 2W
</span>2L = 17.6 - 2W
L = (17.6 - 2W) / 2
<span>17.6 = 2L + 2W
</span>2W = 17.6 - 2L
<span>W = (17.6 - 2L) / 2</span>
Hello! x is 45 degrees because you subtract 75 and 30 to get 45 and it looks very much like a 45 degree angle. brainlist would be much appreciated i hope your day is going great because you are great :)
The least possible sum is 6 and 4. If your having problems, write down the factors and choose the pair that adds up the smallest number :)
