00:10assalamu alaykum dear students

00:12this video

00:14section b question number two

00:16part four

00:18part a

00:20part a

00:22computer is matematic mean by taking

00:24a degree 25

00:26this video is a table

00:28so

00:30you have to

00:32determine

00:34so

00:36you have to

00:38determine

00:40so

00:42this

00:44is

00:46a

00:48a

00:50a

00:52a

00:540 to 10

00:5610 to 20

00:5820 to 30

01:0030 to 40

01:0240 to 50

01:04now

01:06we can have

01:0820

01:104

01:125

01:149

01:166

01:1715

01:1815

01:1917

01:2017

01:2117

01:2217 plus 3

01:2320

01:24now we are going to take the midterm of the classes which labeled as x here

01:26we get

01:28preceding values of x by adding 10

01:3015 plus 10 25

01:3225 plus 10 35

01:3435 plus 10 is equal to 45

01:36now d is equal to x minus a

01:38we are going to follow the section of the equation where a is equal to 25

01:42so x minus a

01:445 minus 25 is equal to minus

01:4620

01:4815 minus 25 is equal to minus 10

01:5025 minus 25 is equal to 0

01:5235 minus 25 is equal to 10

01:5435 minus 25 is equal to 10

01:5645 minus 25 is equal to 20

01:58so sum of definition from mean is always equal to 0

02:02when you are going to add this d column

02:04so sum will be equal to 0

02:06now we are going to find fd

02:10minus 16 minus 20

02:122 into raised power

02:142 into minus 10 is equal to minus 26

02:16into 0 is 0

02:185 into 10 is 50

02:204 into 20 is equal to 80

02:22then we have

02:24summation fd is equal to 50

02:26because

02:28look at this

02:3060 20 minus 80 plus 80

02:32cancel each other

02:34and remaining only figure is 50

02:36now arithmetic means

02:38which is in that method

02:40x bar is equal to a

02:42plus mission fd

02:4312 by mission f

02:44a is equal to 25

02:46plus 50

02:4712 by 20

02:480 is cancelled by 0

02:50so we have

02:5225 plus 2.5

02:54xy is equal to 27.5

02:56this is our answer

02:58look at this

03:00it is lies in the

03:02same

03:04point

03:06to 30

03:07now we will move to the

03:08b part of the

03:10question number 4

03:12section b under question

03:142

03:16so

03:18find the distance between the

03:22centers a and b if a is equal to 6 centimeter

03:26c d is equal to 4 centimeter

03:28c d is equal to 4 centimeter

03:30b d is equal to 5 centimeter

03:32here is the solution

03:34so we have

03:36drawn this diagram

03:40not exactly as

03:44not exactly as a given measurement

03:46so a d is equal to 6 centimeter

03:48d is equal to 6 centimeter

03:50d is equal to 4 centimeter

03:52d is equal to 4 centimeter

03:54d b is equal to 5 centimeter

03:56a d is 6 centimeter

03:58d b 5 centimeter

04:00c d is equal to 4 centimeter

04:02a b this is the distance from

04:04a to b

04:06we have to be determined

04:08in triangle a d c

04:10a d c

04:12a c

04:14a c

04:16a c is equal to 80

04:18square minus c d whole

04:20square

04:22the first theorem

04:246k minus 4 square 36

04:26minus 16

04:2820 and a c is equal to plus

04:30minus 200

04:32under root 5

04:34now in triangle c d b

04:36c b scale is equal to

04:38bt whole square minus c d whole square

04:404 centimeter whole square

04:42minus 4 centimeter whole square

04:4325 minus 6

04:4425 minus 16

04:4625 minus 16

04:48which is equal to 9

04:50so taking square root of both side

04:52c b is equal to plus minus 3

04:54so a b is equal to

04:56a b plus c b

04:58plus minus 2 underscore 5

05:00plus minus 3

05:02so

05:04you will get this

05:06value after solving this

05:08under root 5

05:10and then multiply by 2

05:12and then we will once

05:14add in minus values

05:16then we will add in

05:18plus values

05:20i hope you will find this

05:22solution useful if you have any question

05:24and query query you can ask me

05:26in the comment section

05:28thanks for watching
