Re: Snepco Past Questions by Nobody: 5:22pm On Oct 14, 2020 |
NisforNicky: 2:30AM - 4:00AM is 1.5 hrs. The athlete did this particular set of run for 6 days, i.e, In that week, he ran 6 x 1.5 hrs = 9 hrs in the morning. 2:00PM - 4.30pm is 2.5 hrs. The athlete did this particular set of run for 4 days, i.e, In that week, he ran 4 x 2.5 hrs = 10 hrs in the evening Therefore, the total number of hrs the athlete ran that week is 9 + 10 = 19 hrs. According to the question, average speed is 8km/hr Now, the question is asking for the total distance traveled in that week in kilometres. So lets solve Distance = speed x time therefore, Distance = 8 x 19 = 152km 1 Like |

Re: Snepco Past Questions by NisforNicky: 6:05pm On Oct 14, 2020 |
ennydammy11: list all the data in order from smallest to largest then look for where 12 is on the row (11th term in this case) that is the rank/p0sition (n) of 12. the big N is the total no. of terms 1 Like |

Re: Snepco Past Questions by Nobody: 7:46pm On Oct 14, 2020 |
NisforNicky: Lolzzz... Thanks bro As regarding the questions on percentile, median, inter-quartile and their likes,,,,, I think the table given is not representing the right information. Check up SPLENDID25's last message. I think he put forth a reasonable assumption as regarding the table. The 2nd row should represent the frequency of the values given in the 1st row.. I'm sure(not 100%) it was a mistake from them. 1 Like |
Re: Snepco Past Questions by Nobody: 7:49pm On Oct 14, 2020 |
SPLENDID25:Nice... You assumed the lower row to be that of frequency, right? |
