Step-by-step explanation:
1)......mean= sum of observations/ total observations
= 5.2+8.4+4.3+6.7+5.8/5= 6.08
median= n=5(odd)=n+1/2=6/2=3rdterm= 5.8( when arranged in ascending order).....
mode= 3median- 2meam= 3×5.8-2×6.08= 5.24
range=8.4-4.3=4.1(when done A.O)
2)......mean= -2-13-13-5-7/5= -8
median= 3rd term= -5.....(n=5..odd)(when done A.o)
mode=largest frequency= -13
range= -13-(-2) = -13+2= -11(A.O)
3).....mean= sum/no.= 8+6+13/2+17/2+15/2+7+8+11/2+7+8//10=7.2
median=n=10(even)
=
mode= 8
range=8.5-5.5=3
median:==
(10/2)+(10/2+1)//2=5 term + 6term/2=7+7.5=14.5/2=7.25
4)....
5)...remove 62...then 73will be having highest frequency
C = (5,4)
D = (4,2)
Dilation with factor 8 => for the same x, y increase by a factor of 8
=> C' = (5, 8*4) = (5, 32)
=> D' = (4, 8*2) = (4, 16)
slope of C'D' = [32 - 16] / [5 -4 ] =16
You can also see that the slope of CD = [4 - 2] / [5 - 4] = 2
Then, the new slope is 8 times the old slope, this is it was multiplied by the same factor, 8.
Answer: 16
8:15 am is the answer because if u add up all of the timings it will become an hour and a half
And when u minus an hour and a half from 10:45 u get 8:15
Answer:
19 hrs
Step-by-step explanation:
t varies inversely with number of people p
t = k/p
If it takes 7.125 hrs for 8 workers to do the job
K = tp
= 7. 125 x 8
= 57
How many hours will it take if there are 3 workers .
Recall t = k/p
t = 57/3
= 19 hrs
Therefore, It’ll take 19 hrs to Complete the job if there are only three workers.
