Problems with validity.</h3>
It should be noted that in a research, a problem with validity takes place when there's a lack of reliability of the independent variable.
Also, it is a result of lack of representativeness of the independent variable and a lack of impact of the independent variable.
In this case, the researcher sets out to measure drug use on US college campuses by asking a representative sample of undergraduates whether they are currently receiving federal grants or loans. It should be noted that the question asked doesn't relate to the research.
In conclusion, there's a problem with validity.

Answer:
58% of 121 by using 10% is 70.18.
Step-by-step explanation:
58% is about equal to 60%, or 6 times 10%. 10% of 121 is 12.1.
12.1 * 6 = 72.6
To take this further, 58% is 2% less than 60%, or 2 times 1%. 1% of 121 is 1.21.
72.6 - (1.21 * 2) = 72.6 - 2.42 = 70.18

Answer:
B
Step-by-step explanation:
Law of Sines:
Sin(a)/opposite side=Sin(b)/opposite
Sin(55)/x=sin(90)/59
Sin(55)/(Sin(90)/59)
sin(90)=1
Sin(55)/(1/59)
59Sin(55)=48.33
