Answer» Answer: Step-by-step explanation: plz mark as BRAINLIEST answer and thx for the brilliant question FIRST 8 prime no. = 2, 3, 5, 7, 11, 13, 17, 19. Mean = SUM of all observations/total no. of observation = (2+3+5+7+11+13+17+19)/8 = 77/8 = 9.625 So, mean of first 8 prime number = 9.625

1.

Find the Arithmetic mean of first 8 number

Answer»

Answer:

Step-by-step explanation:

plz mark as BRAINLIEST answer and thx for the brilliant question

FIRST 8 prime no. = 2, 3, 5, 7, 11, 13, 17, 19.

Mean = SUM of all observations/total no. of observation

= (2+3+5+7+11+13+17+19)/8

= 77/8

= 9.625

So, mean of first 8 prime number = 9.625

2.	Tan2 x – sin2x = tan2 x sin2 x
Answer» We have to prove that (tan x)^2 - (sin x)^2 = (tan x)^2 * (sin x)^2 Start from the LEFT HAND side: (tan x)^2 - (sin x)^2 use tan x = sin x / COS x (sin x)^2/(cos x)^2 - (sin x)^2 => [(sin x)^2 - (sin x)^2(cos x)^2]/(cos x)^2 => (sin x)^2[1 - (cos x)^2]/(cos x)^2 => (sin x)^2 [(sin x)^2 / (cos x)^2] => (tan x)^2 * (sin x)^2 which is the right hand side. This PROVES that (tan x)^2 - (sin x)^2 = (tan x)^2 * (sin x)^2 HOPE THIS HELPS PLZ MARK AS BRAINLIEST

2.

Tan2 x – sin2x = tan2 x sin2 x

Answer»

We have to prove that (tan x)^2 - (sin x)^2 = (tan x)^2 * (sin x)^2

Start from the LEFT HAND side:

(tan x)^2 - (sin x)^2

use tan x = sin x / COS x

(sin x)^2/(cos x)^2 - (sin x)^2

=> [(sin x)^2 - (sin x)^2*(cos x)^2]/(cos x)^2

=> (sin x)^2[1 - (cos x)^2]/(cos x)^2

=> (sin x)^2 * [(sin x)^2 / (cos x)^2]

=> (tan x)^2 * (sin x)^2

which is the right hand side.

This PROVES that (tan x)^2 - (sin x)^2 = (tan x)^2 * (sin x)^2

8.

Can you please solve this√2(sinx+cosx) = √3

Answer»

Step-by-step explanation:

Given:

√2(sinx + cosx) = √3

Squaring both the sides

2(sinx+cosx)^2 = 3

or (sinx +cosx)^2 = 3/2

or sin^2 X + cos^2x +2SinxCosx = 3/2

or 1 + 2SinxCosx = 3/2

or 2 SinXCosX = 3/2 -1

or 2SinxCosX = 3-2/2

or 2 SinXCosX = 1/2.....(1)

Now LHS = √2(sinx + cosx)

or 2(sinx+cosx)^2

or 2(sin^2x + cos^2x +2SinxCosx)

or 2(1+ 2SinxCosx)

or 2 + 4SinXCosX

or 2 + 2(2SinxCosx)

or 2 + 2(1/2) (from 1)

or 2 +1 = 3 = RHS....... Answer

Step-by-step explanation:

GIVEN Padmavathi speaks the truth 3 TIMES out of 4 and vareesha speaks the truth 7 times out of 10. both of them ASSERT that a white hat has been removed from a basket containing hats of 6 different colours. what is the probability of finding the white hat in the basket

P(A) (truth) = 3/4
P(A) (lies) = 1/4
P(B) (truth) = 7/10
P(B) (lies) = 3/10
Now P(M) = 1/6 X 3/4 x 7/10
= 21 / 240
Suppose C is an event
So P( C ) = 1/4 x 1/5
= 1/20
P(D) = 3/10 x 1/5
= 3/50
P(N) = 1/20 x 3/50 x 5/6
= 1/400
So P(W) = P(M) / P(M) + P(N)
= 21 / 240 / 21 / 240 + 1/400
= 7/80 / 7/80 + 1/400
= 7/80 / 35 + 1 / 400

For example, the triangle contains an angle A, and the ratio of the SIDE opposite to A and the side opposite to the right angle (the hypotenuse) is called the sine of A, or sin A; the other trigonometry functions are defined similarly. These functions are properties of the angle A independent of the size of the triangle, and calculated values were tabulated for many angles before computers made trigonometry tables OBSOLETE.

41.

javid is three times as old as his son 5 years later he will be two and half times as old as his son find the present age of javid and his son

Answer»

Answer:

javed age is 45 years and son age is 15 years

Step-by-step explanation:

let father age is X

and son age is y

so according to QUESTION

x =3y or x-3y =0 (i)

after 5 years x+5 = (y+5)*5/2

x + 5 = ( x /3 + 5 ) *5/2 (as y = x/3)

x + 5 = ( x + 15 ) * 5/6

6 x + 30 = 5 x + 75

6x -5X = 45

x =45 years

y = 15 years

Write the equation of a line which is parallel to the line whose equation is 5x -3 Y + 11 = 0

Answer»

Step-by-step EXPLANATION:

As in PARALLEL LINES,

A1/A2 =B1/B2 not equal to C1/C2

we need to write the equation ,

the second equation is,

10x-6y-12=0

VERIFICATION,

A1/A2 , B1/B2 , C1/C2

5/10 (-3)/(-6) 11/(-12)

1/2 1/2 -11/12

thus,A1/A2=B1/B2 not equal to C1/C2

therefore ,10x-6y-12=0 is true equation

Answer» Step-by-step explanation: balcony length = 20 METERS = 200100=2000 cm. breadth=18 meters=18100=1800 cm. BRICKS length=22.5 cm = 225/10 cm breadth = 10 cm number of bricks = AREA of balcony / area of BRICK = 20001800/22.510 =20001800/(225/10)10 =2000*1800/225 =1600 bricks

48.

the length of a balcony is 20 metre and breadth is 18 metre it is it is also to be with brakes of land 22.5 cm and breadth is 10 centimetre find the number of bricks required

Answer»

Step-by-step explanation:

balcony

length = 20 METERS = 200*100=2000 cm.

breadth=18 meters=18*100=1800 cm.

BRICKS

length=22.5 cm = 225/10 cm

breadth = 10 cm

number of bricks = AREA of balcony / area of BRICK

= 2000*1800/22.5*10

=2000*1800/(225/10)*10

=2000*1800/225

=1600 bricks

Find the Arithmetic mean of first 8 number ​

plz mark as BRAINLIEST answer and thx for the brilliant question

FIRST 8 prime no. = 2, 3, 5, 7, 11, 13, 17, 19.

Mean = SUM of all observations/total no. of observation

= (2+3+5+7+11+13+17+19)/8

= 77/8

= 9.625

So, mean of first 8 prime number = 9.625
