Answer, please please
1 answer:
a) 2, 4, 6, 7, 7, 9, 14
Mean (average): =
= 7
Median (middle number) : 2, 4, 6, 7, 7, 9, 14 = 7
Mode (most common number): 2, 4, 6, <u>7, 7,</u> 9, 14 = 7
Midrange (average of smallest & greatest term): = 8
b) 2, 4, 6, 7, 7, 10, 14
Mean (average): =
= 7.1
Median (middle number) : 2, 4, 6, 7, 7, 10, 14 = 7
Mode (most common number): 2, 4, 6, <u>7, 7,</u> 10, 14 = 7
Midrange (average of smallest & greatest term): = 8
c) the only thing different between part (a) and part (b) is the MEAN
d) 2, 4, 6, 7, 7, 9, 10
Mean (average): =
= 6.4
Median (middle number) : 2, 4, 6, 7, 7, 9, 10 = 7
Mode (most common number): 2, 4, 6, <u>7, 7,</u> 9, 10 = 7
Midrange (average of smallest & greatest term): = 6
The differences between part (a) and part (d) are the MEAN and MIDRANGE

Tricky question. This isn't a ratio question even though it seems like one.
First divide 7 by 4.
With more men, the hours taken to repair a road will be even shorter.
So next divide 6 by 1.75.
Answer : It'll take 3.43 hours to do the job if they work at the same rate.
Hope this helps. - M
