Answer»

Let the total distance be x KM

and total cost be y

now, 10RS for 1st km, and 4Rs. per km for rest

so,

y=1(10)+4(x-1)

y=4x+6,

sub,

x=-2,y=-2

x=-1, y=2

. A box contains 15 red balls, 18 white balls. One ball is taken out of the box at random. What is the probability that the ball taken out will be not red.

Answer»

GIVEN :–

ㅤ

• A box CONTAINS 15 red balls, 18 white balls.

ㅤ

• One ball is taken out of the box at random.

ㅤ

TO FIND :–

ㅤ

• Probability that the ball taken out will be not red = ?

ㅤ

SOLUTION :–

ㅤ

• We know that –

ㅤ

☆ Probability = N(E)/n(S)

ㅤ

▪︎ E → Taken ball is not red.

ㅤ

=> E → Taken ball is white.

ㅤㅤ

=> n(E) = $\bf ^{18} c_{1}$

ㅤ

▪︎ S → One ball TAKE from 33 balls.

ㅤ

=> n(S) = $\bf ^{33} c_{1}$

ㅤ

• So that –

ㅤ

$\bf \implies \:Probability = \dfrac{^{18} c_{1}}{^{33} c_{1}}$

ㅤ

• Using identity –

ㅤ

$\bf \implies ^{n} c_{r} = \dfrac{n!}{(n - r)!(r)!}$

ㅤ

• So that –

ㅤ

$\bf \implies \:Probability = \dfrac{ \dfrac{18!}{(18 - 1)!(1)!}}{\dfrac{33!}{(33 - 1)!(1)!}}$

ㅤ

$\bf \implies \:Probability = \dfrac{ \dfrac{18!}{(17)!}}{\dfrac{33!}{(32)!}}$

ㅤ

$\bf \implies \:Probability = \dfrac{ \dfrac{(18)(17)!}{(17)!}}{\dfrac{(33)(32!)}{(32)!}}$

ㅤ

$\bf \implies \large{ \boxed{ \bf Probability = \dfrac{18}{33}}}$

18.	In the following AP's fill up the missing terms .. 4) __, 7 __, __ 1
Answer» Answer: The missing TERMS in the sequence of A.P are 9, 7, 5, 3, 1 Step-by-step explanation: Given that, the sequence of A.P is __, 7, __, __, 1 Here, a₁ = ?, a₂ = 7, a₃ = ?, a₄ = ?, a₅ = 1 common difference (d) = ? (∵aₓ = a+(n-1)d ) so, a₂ = a+(2-1)d ⇒ 7 = a+d ↔ (1) a₅= a+(5-1)d ⇒1 = a+4d ↔ (2) now, SUBTRACT (1) from (2) ⇒eq.(1) - eq.(2) ⇒ 7-1 = a+d - (a+4d) ⇒ 6 = a+d-a-4d ⇒ 6 = -3d ⇒ d = -2 thus, common difference (d) = -2 By substituting d = -2 in eq.(1) we get, ⇒7 = a+d ⇒7 = a-2 ⇒a = 7 + 2 = 9 ⇒ a = a₁ = 9 So, a₃ = a + (3-1)d ⇒ a₃ = 9 + 2(-2) ⇒ a₃ = 9 - 4 ⇒ a₃ = 5 a₄ = a + (4-1)d ⇒ a₄ = a+3d ⇒ a₄ = 9+3(-2) ⇒ a₄ = 9 - 6 ⇒ a₄ = 3 ∴ the missing terms are 9, 5, 3 the sequence of A.P is 9, 7, 5, 3, 1

18.

In the following AP's fill up the missing terms .. 4) , 7 , __ 1

Answer»

Answer:

The missing TERMS in the sequence of A.P are 9, 7, 5, 3, 1

Step-by-step explanation:

Given that,

the sequence of A.P is __, 7, __, __, 1

Here, a₁ = ?, a₂ = 7, a₃ = ?, a₄ = ?, a₅ = 1

common difference (d) = ?

(∵aₓ = a+(n-1)d )

so, a₂ = a+(2-1)d

⇒ 7 = a+d ↔ (1)

a₅= a+(5-1)d

⇒1 = a+4d ↔ (2)

now, SUBTRACT (1) from (2)

⇒eq.(1) - eq.(2)

⇒ 7-1 = a+d - (a+4d)

⇒ 6 = a+d-a-4d

⇒ 6 = -3d

⇒ d = -2

thus, common difference (d) = -2

By substituting d = -2 in eq.(1) we get,

⇒7 = a+d

⇒7 = a-2

⇒a = 7 + 2 = 9

⇒ a = a₁ = 9

So,

a₃ = a + (3-1)d

⇒ a₃ = 9 + 2(-2)

⇒ a₃ = 9 - 4

⇒ a₃ = 5

a₄ = a + (4-1)d

⇒ a₄ = a+3d

⇒ a₄ = 9+3(-2)

⇒ a₄ = 9 - 6

⇒ a₄ = 3

∴ the missing terms are 9, 5, 3

the sequence of A.P is 9, 7, 5, 3, 1

10). A bicycle wheel whose diameter is 77cm makes 50 revolutionsin 20 seconds. Find the speed in km/h

Answer»

Answer:

HERE IS YOUR ANSWER ...

Step-by-step explanation:

DIAMETER = 77 cm

= 0.00077 km

TIME = 20s

= 0.00555 h

Circumference= 22/7 x 77/100000

= 0.00242 Km

50 revolution= 0.00242 x 50

= 0.121

Speed = distance/time

= 0.121/0.00555

= 12100/555

= 21.8 km/h

$\sf{\underline{\boxed{\large{\blue{\mathsf{Correct\: Question}}}}}}$

_______________________

$\sf{\underline{\boxed{\large{\blue{\mathsf{Solution}}}}}}$

$\sf\leadsto Total \: Profit \implies Rs2500$

profit goes to charity

$\sf\longrightarrow$ 20% of profit

$\sf\longrightarrow$ 20% of 2500

$\sf\longrightarrow \dfrac{20}{100}\times 2500$

$\sf\longrightarrow \dfrac{20}{\cancel{100}}\times \cancel{2500}$
