The answer is Internal Validity.

Internal Validity is high in an experiment. when it demonstrates persuasively that changes in behavior are caused by the independent variable and not by unknown factors.

What is Internal Validity?

  • Internal validity is defined as the degree to which the observed results represent the truth in the population under investigation and are not the consequence of methodological flaws.
  • Internal validity is the degree of certainty that the causal link being examined is reliable and unaffected by other factors or variables.
  • The extent to which study results may be extended (generalized) to other contexts, groups, or events is referred to as external validity.

Answer:

x = 85°

Step-by-step explanation:

Because the sum of the angles in a triangle is 180°, we can find ∠CDB.

180° - ∠CBD - ∠BCD = ∠CDB.

180° - 35° - 50° =

180° - 85° =

95°

So, ∠CDB is 95°

Then, because a line has 180°, we can find ∠CDA.

180° - ∠CDB = ∠CDA.

180° - 95° = 85°

So, x = 85°

about 70,000 people live in a circular region with a 30-mile radius. find the population density in people per square mile.
bezimeni [28]

Solve for the area of the circular region first:

A = pi*r^2

A = pi*(30 mi)^2

A = 2827.43 mi^2

Density = 70000 people/2827.43 mi^2

Density = 24.76 = 25 people/mi^2 <--ANSWER Plz vote brainnliest

Answer:

d = 14

Step-by-step explanation:

\sin \: 45 \degree =  \frac{a}{7 \sqrt{2} }  \\  \\a = 7 \sqrt{2}  \sin \: 45 \degree  \\  \\ a =  7\sqrt{2}   \times  \frac{1}{ \sqrt{2} }  \\  \\ a = 7 \\  \\  \sin \: 30 \degree =  \frac{a}{d}  \\  \\  \frac{1}{2}  =  \frac{7}{d}  \\  \\ d = 2 \times 7 \\  \\ d = 14
