Answer:
I think it would be 4×n-3 = n+12
2.291827331. That is what I got.
Answer:
hope it helps you
Step-by-step explanation:
To make such a frequency distribution table, first, write the class intervals in one column. Next, tally the numbers in each category based on the number of times it appears. Finally, write the frequency in the final column. A frequency distribution table drawn above is called a grouped frequency distribution table.
Answer:
m = -30
m = slope
Step-by-step explanation:
(1,57) and (2,27)
(x1,y1) and (x2,y2)
y2 - y1. 27 - 57
---------- =. ---------- =. -30/1 = -30
x2-x1. 2 - 1
Time taken by a regular bus to reach its destination = 3 1/4 hours
= 13/4 hours
Time taken by the express bus to make the same trip = 2 1/2 hours
= 5/2 hours
Time that can be saved by taking the express bus = (13/4) - (5/2) hours
= (13 - 10)/4 hours
= 3/4 hours
So 3/4 hours can be saved by taking the express bus rather than the regular bus. The correct option among all the options given in the question is option "C". I hope the procedure is simple enough for you to understand.
