Based on the information given, it can be noted that the problem with the research is the problem of validity.

<h3>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.

What is the value of x?
OLga [1]

Answer:

x = 24

Step-by-step explanation:

Pythagorean Theorem: a² + b² = c²

<em>a</em> = a leg

<em>b</em> = another leg

<em>c</em> = hypotenuse

Step 1: Plug in known variables

x² + 10² = 26²

Step 2: Evaluate

x² + 100 = 676

Step 3: Isolate <em>x </em>term

x² = 576

Step 4: Isolate <em>x</em>

√x² = √576

x = 24

Answer:

Step-by-step explanation:

we would apply the law of Cosines which is expressed as

a² = b² + c² - 2abCosA

Where a,b and c are the length of each side of the triangle and A is the angle corresponding to a. Likening the expression to the given triangle, it becomes

q² = p² + r² - 2(p × r)CosQ

q² = 12² + 6² - 2(12 × 6)Cos92

q² = 144 + 36 - 2(72)Cos92

q² = 180 - 144 × - 0.0349

q² = 180 + 5.0256

q² = 185.0256

q = √185.0256

q = 13.6 to the nearest integer
