66/35 = Improper Fraction
66 - 35 = 31
So, 66 can go in 31 1 time.
So 1 will be our whole number. 31 will be d numerator and 35 will be d denominator.
1 31/35
So, 66/35 in mixed number is 1 31/35.
Hope I helped ya!!! xD
Answer: 735π.
Explanation:
The area of a circle is given by: A= πr^2. The radius of the circle here is 7.
So the area of the circle is:
π7^2=49π
You then multiply 49π by 15 to get the volume:
49π*15=735π
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.
