Unfortunately, Nicholas' steps in simplifying the fraction is not reflected in the question. However, the general idea of the simplifying fraction is to find the greatest common factor (GCF) of both the numerator and the denominator. In this case, the GCF is 10. Then, divide both numbers by the GCF. The answer for this item should be 2/3.
Take .26 • 52 = 13.52
So 26% of 52 = 13.52
Answer:

Step-by-step explanation:
To convert from degrees to radians you multiply by 

2(3)^3 + 4(3)^2-6(3)
2x 27 + 4x9 - 18
54 + 36 -18
= 72
Answer:
Among the given samples the sample which constitute a biased sample is given by, the sample obtained by,
'Surveying randomly among seventh grade girls of a school to determine what theme the whole school would prefer for the dance.'
Step-by-step explanation:
Among the given samples the sample which constitute a biased sample is given by, the sample obtained by,
'Surveying randomly among seventh grade girls of a school to determine what theme the whole school would prefer for the dance.' since the choices of those seventh grade girls in the sample may not reflect those of the whole school.
