Answer»

Answer:

Given observations: 10 ,12 ,15 ,8 ,10 ,12 ,12 ,8 ,10 ,8 ,12 ,11 ,11.

First arrange these observations in ASCENDING ORDER

8, 8, 8, 10,10,10,11 ,11 ,12 ,12 ,12 ,12 ,15

The total NUMBER of terms = n = 13

Median = {(n+1)/2}th term = {(13+1)/2}th term

= 7TH term = 11 (the 7th term in the arranged observation LIST)

MEDIAN = 11(Ans)

Since, the number '12' is repeated for the most number of times

Therefore, MODE = 12(Ans)

Answer»

$\Large{\underline{\underline{\mathfrak{\bf{Question}}}}}$

If ( x - 1/x ) = 3+2√2 , Find the VALUE of 1/4(x³ - 1/x³)

$\Large{\underline{\underline{\mathfrak{\bf{Solution}}}}}$

$\Large{\underline{\mathfrak{\bf{\pink{Given}}}}}$

( x - 1/x ) = 3+2√2 .........(1)

$\Large{\underline{\mathfrak{\bf{\orange{Find}}}}}$

Value of 1/4(x³ - 1/x³)

$\Large{\underline{\underline{\mathfrak{\bf{Explanation}}}}}$

We know,

★ ( a-b)² = a² + b² - 2ab

So,

★ ( x - 1/x )² = x² + 1/x² - 2.x.1/x

➥ (x - 1/x)² = x² + 1/x² - 2

Now, keep value by equ(1)

➥ (3+2√2)² = x²+1/x² - 2

➥3²+(2√2)²+2.3.2√2 = x²+1/x² - 2

➥ x² + 1/x² = (9+8+12√2)-2

➥ x² + 1/x² = 15 + 12√2

Again,

★(a³-b³) = (a-b)(a²+b²+ab)

So,

➥ (x³ - 1/x³ ) = (x - 1/x)(x² + 1/x² + x . 1/x)

➥(x³ - 1/x³ ) = (x - 1/x)(x² + 1/x² + 1)

keep value by equ(1) and (2)

➥ (x³ - 1/x³ ) = ( 3+2√2)(15+12√2+1)

➥ (x³ - 1/x³ ) = (3+2√2)(16+12√2)

➥ (x³ - 1/x³ ) = 4(3+2√2)(4+3√2)

➥ (x³ - 1/x³ ) = 4(12+9√2+8√2+12)

➥ (x³ - 1/x³ ) = 4(24+17√2)

Now, calculate ,

➥ 1/4 (x³ - 1/x³ ) = 4(24+17√2)/4

➥ 1/4 (x³ - 1/x³ ) = (24 + 17√2) (Ans.)

The length breadth and height of a cuboid are in the ratio of 7 is to 6 is to 5 if the surface area of the cuboid is 1926 metre cube find the find its dimensions

Answer»

Step-by-step EXPLANATION:

Surface area of cuboid = 2(lb+bh+hl)

LET the ratio be X

Length = 7x

Breadth = 6x

Height = 5x

= 2(7x*6x+6x*5x+5x*7x) = 1926

= 2(42x+30x+35x) = 1926

= 2*107x = 1926

= 214x = 1926

= x = 9

7x = 7*9 = 63

6x = 6*9 = 54

5x = 5*9 = 45

What is the surface area of a cone in inches when the slant height is 6 inches and the diameter is 4 inches

Answer»

Answer:

Total surface AREA of a cone:

A = L + B

= πrs + πr^2

= πr(s + r)

= πr(r + √(r^2 + h^2))

Radius r = 2 in

HEIGHT h = 5.6 in (approximately)

SLANT height s = 6 in

If 2 is added to the numerator and denominator it becomes 9/10 and if 3 is subtracted from the numerator and denominator it become 4/5. Find the fractions.

$\setlength{\unitlength}{1.0 cm}}\begin{picture}(12,4)\thicklines\put(1,1){\line(1,0){6.5}}\put(1,1.1){\line(1,0){6.5}}\end{picture}$

Let the fraction be x/y.

If 2 is added to the numerator and denominator fraction becomes 9/10 so, We have:

(x + 2)/(y + 2) = 9/10

➠ 10(x + 2) = 9(y + 2)

➠ 10x + 20 = 9y + 18

➠ 10x – 9y + 20 = 9y – 9y + 18

➠ 10x – 9x + 20 – 20 = 18 – 20

➠ 10x – 9y = -2 ………. (i)

If 3 is SUBTRACTED from numerator and denominator the fraction becomes 4/5 so, We have:

(x – 3)/(y – 3) = 4/5

➠ 5(x – 3) = 4(y – 3)

➠ 5x – 15 = 4Y – 12

➠ 5x – 4y – 15 = 4y – 4y – 12

➠ 5x – 4y – 15 + 15 = – 12 + 15

➠ 5x – 4y = 3 ………. (ii)

So, We have:

10x – 9y = – 2 ………. (iii)
And 5x – 4y = 3 ………. (iv)

Multiplying both sided of equation (iv) by 2, We get:

10x – 8y = 6 ………. (v)

Now, solving equation (iii) and (v),

We get:

10x – 9y = -2

10x – 8y = 6

⠀⠀⠀⠀- y = - 8

⠀⠀⠀⠀⠀y = 8

Substituting the value of y in equation (iv),

We get:

5x – 4 × (8) = 3

➠ 5x – 32 = 3

➠ 5x – 32 + 32 = 3 + 32

➠ 5x = 35

➠ x = 35/5

➠ x = 7

Therefore, fraction becomes 7/8.
