34 because 24 is 6x4 and 40 is 6.5 but you obviously round up so 7x6 so18 free songs is is 6x3 you just take away 6 to your number so 40-6+=34 so 34
Answer: B
Step-by-step explanation:
Histogram is a statistical graph with the use of bar. The bar are not seperated unlike bar chart.
0.320 to 0.329 and 0.360 to 0.369 are of the same frequency which is equal to one. 0.350 to 0.359 is of frequency 2 a little above frequency 1.
Option B and D are very close to each other in value representation. But the frequency of 0.350 to 0.359 in option D is 3. This renders option D invalid and make option B the correct answer.
From the mean of 13,
the value of the stated summation will be given by:
(5.7-13)+(10.2-13)+(11.9-13)+(13.3-13)+(17.6-13)+(19.3-13)
=-7.3+(-2.8)+(-1.1)+0.3+4.6+6.3
=0
Hence the summation indicated also known as mean absolute deviation is 0.
