Answer» Question :- The average of 10 observations is 3.5 . If two observations namely 3.5 and 2.5 are SUBTRACTED . Find the new average ? Answer :- Given :- The average of 10 observations is 3.5 . 2 of the observations namely 3.5, 2.5 are subtracted Required to find :- Find the new average of the remaining observations Formulae used :- $\large{\leadsto{\boxed{\rm{Mean = \dfrac{Sum \: of \; the \; observations}{Number \; of \; observations }}}}}{\bigstar}$ $\large{\leadsto{\boxed{\rm{Sum \; of \; the \; observations = Mean \times Number \; of \; observations }}}}}{\bigstar}$ Solution :- Given that, The average of 10 observations is 3.5 . If 2 of the observations namely 3.5 , 2.5 are subtracted or removed . He asked us to find the new average . So, Consider the first statement . The average of 10 observations is 3.5 No. of observations = 10 Hence, Using the formula; $\large{\leadsto{\boxed{\rm{Sum \; of \; the \; observations = Mean \times Number \; of \; observations }}}}}{\bigstar}$ So, ➾ Sum of the observations = 3.5 x 10 ➾ Sum of the observations = 35 It is also given that, If 3.5 , 2.5 are removed or subtracted from the observations So, 3.5 + 2.5 = 6.0 Here, Divide this from the WHOLE sum . So, ➾ New sum of the observations = 35 - 6 ➾ New sum of the observations = 29 Hence, New average = ? By using the formula $\large{\leadsto{\boxed{\rm{Mean = \dfrac{Sum \: of \; the \; observations}{Number \; of \; observations }}}}}{\bigstar}$ So, $\longrightarrow{\tt{ New \; average = \dfrac{ New \; sum \; of \; the \; observations }{Number \; of \; observations }}}$ Number of observations = 8 $\longrightarrow{\tt{ New \; average = \dfrac{29 }{8}}}$ $\longrightarrow{\tt{ New \; average = 3.625 }}$ $\large{\leadsto{\boxed{\rm{ New \; average = 3.625 }}}}$ Note :- A small tip to solve these solutions is whenever mean is given you need to find the sum and whenever sum is given find the mean .

The average of 10 observation is 3.5. if two observation namely 3.5 and 2.5 are deleted find the new average

Answer»

Question :-

The average of 10 observations is 3.5 . If two observations namely 3.5 and 2.5 are SUBTRACTED . Find the new average ?

Answer :-

Given :-

The average of 10 observations is 3.5 .

2 of the observations namely 3.5, 2.5 are subtracted

Required to find :-

Find the new average of the remaining observations

Formulae used :-

$\large{\leadsto{\boxed{\rm{Mean = \dfrac{Sum \: of \; the \; observations}{Number \; of \; observations }}}}}{\bigstar}$

$\large{\leadsto{\boxed{\rm{Sum \; of \; the \; observations = Mean \times Number \; of \; observations }}}}}{\bigstar}$

Solution :-

Given that,

The average of 10 observations is 3.5 .

If 2 of the observations namely 3.5 , 2.5 are subtracted or removed .

He asked us to find the new average .

So,

Consider the first statement .

The average of 10 observations is 3.5

No. of observations = 10

Hence,

Using the formula;

$\large{\leadsto{\boxed{\rm{Sum \; of \; the \; observations = Mean \times Number \; of \; observations }}}}}{\bigstar}$

So,

➾ Sum of the observations = 3.5 x 10

➾ Sum of the observations = 35

It is also given that,

If 3.5 , 2.5 are removed or subtracted from the observations

So,

3.5 + 2.5 = 6.0

Here,

Divide this from the WHOLE sum .

So,

➾ New sum of the observations = 35 - 6

➾ New sum of the observations = 29

Hence,

New average = ?

By using the formula

$\large{\leadsto{\boxed{\rm{Mean = \dfrac{Sum \: of \; the \; observations}{Number \; of \; observations }}}}}{\bigstar}$

So,

$\longrightarrow{\tt{ New \; average = \dfrac{ New \; sum \; of \; the \; observations }{Number \; of \; observations }}}$

Number of observations = 8

$\longrightarrow{\tt{ New \; average = \dfrac{29 }{8}}}$

$\longrightarrow{\tt{ New \; average = 3.625 }}$

$\large{\leadsto{\boxed{\rm{ New \; average = 3.625 }}}}$

Note :-

A small tip to solve these solutions is whenever mean is given you need to find the sum and whenever sum is given find the mean .

Answer» ANSWER Let the speed of the train be x km/hr. Then Time taken to TRAVEL a distance of 480km= x 480 hr Time taken by the train to travel a distance of 480km with the speed (x−8)km/hr= x−8 480 hr It is given that if the speed had been 8km/hr LESS, then the train WOULD have taken 3 hours more to cover the same distance ∴ x−8 480 = x 480 +3 ⇒ x−8 480 − x 480 =3⇒ x(x−8) 480(x−x+8) =3⇒ x(x−8) 480×8 =3 ⇒3x(x−8)=480×8⇒x(x−8)=160×8⇒x 2 −8x−1280=0 This is the required quadratic EQUATION

Answer» Step-by-step explanation: PRINCIPLE = RS 10000, After 1 year amount = Rs 11200 so INTEREST after 1 year = Rs 1200 Amount = P(1+R/100)T 11200 = 10000(1+R/100)1 R = 12% Interest for second year = 11200(1+12/100)1 - 11200 = Rs 1344 Amount after 3 year = 10000(1+12/100)3 = Rs 14049.28 4.1 Read more on Brainly.in - brainly.in/question/3954368#readmore

3. A man invests 10000 for 3 years at a certain rate of interest, compounded annually. At theend of one year, it amounts to 11200. Calculate :(i) the rate of interest per annum;(ii) the interest accrued in the second year;(iii) the amount at the end of the third year.

Answer»

Step-by-step explanation:

PRINCIPLE = RS 10000, After 1 year amount = Rs 11200 so INTEREST after 1 year = Rs 1200

Amount = P(1+R/100)T

11200 = 10000(1+R/100)1

R = 12%

Interest for second year = 11200(1+12/100)1 - 11200 = Rs 1344

Amount after 3 year = 10000(1+12/100)3 = Rs 14049.28

(i) (3x - 1)^2 – (3x - 2) (3x + 1)

Answer»

Step-by-step explanation:

(3X-1)^2 - (3x-2)(3x+1)

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6X + 1 - (9x^2 + 3x - 6x -2)

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3

or....

(3x-1)^2 - (3x-2)(3x+1)

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,in that case we can FIND the solution of this equation by

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,in that case we can find the solution of this equation by-3x + 3 = 0

(3x-1)^2 - (3x-2)(3x+1)= 9x^2 - 6x + 1 - (9x^2 + 3x - 6x -2)= 9x^2 - 6x + 1 - 9x^2 - 3x + 6x + 2= -3x + 3 If this was an equation (3x-1)^2 - (3x-2)(3x+1) = 0,in that case we can find the solution of this equation by-3x + 3 = 0x = 1

32.	The middle digit of a number between 100 and 1000 is zero, and the sum of other digits is 11. Ifthe digits are reversed, the number so formed exceeds the orginal number by 495. Find the number
Answer» Answer: 308 Step-by-step explanation: Let the number in 100S digit be X, Let the number in 1s digit be y, Then,the number would be x0y : 100x+y Condition 1: Sum of the digits : x+y=11.....(i) If it is reversed ,it would be y0x : 100y+x, The DIFFERENCE between them: 100x+y -(100y+x) = -495 100x+y-100y-x =-495 99x-99y = -495 (divided by 99) x-y=-5.....(ii) Adding (i) and (ii), we get, (x+y)+(x-y)=11+(-5) x+y+x-y=11-5 2x=6 ∴ x=3 Substituting value of x in (i), x+y=11 3+y=11 y=11-3 ∴ y=8 ∴The number is 308 hope it HELPS..... if you are satisfied with my answer pls marks as brainliest.. thank you....

The middle digit of a number between 100 and 1000 is zero, and the sum of other digits is 11. Ifthe digits are reversed, the number so formed exceeds the orginal number by 495. Find the number

Answer»

Answer:

308

Step-by-step explanation:

Let the number in 100S digit be X,

Let the number in 1s digit be y,

Then,the number would be x0y : 100x+y

Condition 1: Sum of the digits : x+y=11.....(i)

If it is reversed ,it would be y0x : 100y+x,

The DIFFERENCE between them: 100x+y -(100y+x) = -495

100x+y-100y-x =-495

99x-99y = -495 (divided by 99)

x-y=-5.....(ii)

Adding (i) and (ii), we get,

(x+y)+(x-y)=11+(-5)

x+y+x-y=11-5

2x=6

∴ x=3

Substituting value of x in (i),

x+y=11

3+y=11

y=11-3

∴ y=8

∴The number is 308

hope it HELPS.....
