AnswEr : $\\ \\$

$\star \sf \: Given\begin{cases} \: \: \: { \bf{Possible \: events = 6 }}\\ \\ \: \: \:{ \bf{No. \: on \: dice = 1,<klux>2</klux>,3,4,5 \: and \: 6}} \end{cases}$ $\\$

Now, we know the required formula for finding Probability.

That is, $\\$

$\: \: \: \: \star \: \: {\boxed{ \sf{ \purple{Probability = \dfrac{No. \: of \: favourable \: outcomes}{Total \: no. \: of \: favourable \: outcomes}}}}}$

(I) A Prime Number : $\\$

Prime numbers = 2, 3 & 5

$\\$

No. of favourable outcomes = 3

$\bigstar \:{ \underline{\sf \: Probability : }} \\ \\ : \implies\sf \: \dfrac{3}{6} \\ \\ : \implies\sf \: \blue{\dfrac{1}{2}} \\ \\$

(ii) A number lying between 2 and 5 : $\\$

Number's lying between 2 and 5 = 3 & 4

$\\$

No. of favourable outcomes = 2

$\bigstar \:{ \underline{\sf \: Probability : }} \\ \\ : \implies\sf \: \dfrac{2}{6} \\ \\ : \implies\sf \: \green{\dfrac{1}{3}} \\ \\$

(III) An EVEN number : $\\$

Even numbers = 2, 4 & 6

$\\$

15.

Tell me answer tell only answer plz.............

Answer»

Answer:

450

Step-by-step EXPLANATION:

As the coins are in the form of THIN cylinder

Volume of each coin = π×(0.75)²×0.2 =0.1125π cm³

Volume of MELTED cylinder = π× (2.25)²× 10 = 50.625π cm³

number of coin REQUIRED = (volume of melted cylinder)/(volume of each coin)

= 50.625π/0.1125π = 450 coins

Construct an angle of 90° at the initial point of a given ray and justify the construction

Answer»

ANSWER

Steps of CONSTRUCTION

DRAW a line segment OA.

Taking O as center and any radius, draw an arc cutting OA at B.

Now, taking B as center and with the same radius as before, draw an arc intersecting the previously drawn arc at point C.

With C as center and the same radius, draw an arc cutting the arc at D.

With C and D as center and radius more than

2

1

CD, draw two arc intersecting at P.

Join OP.

Thus, ∠AOP=90

o

JUSTIFICATION

Join OC and BC

Thus,

OB=BC=OC [Radius of equal arcs]

∴△OCB is an equilateral triangle

∴∠BOC=60

o

Join OD,OC and CD

Thus,

OD=OC=DC [Radius of equal arcs]

∴△DOC is an equilateral triangle

∴∠DOC=60

o

Join PD and PC

Now,

In △ODP and △OCP

OD=OC [Radius of same arcs]

DP=CP [Arc of same radii]

OP=OP [Common]

∴△ODP≅△OCP [SSS congruency]

∴∠DOP=∠COP [CPCT]

So, we can say that

∠DOP=∠COP=

2

1

∠DOC

∠DOP=∠COP=

2

1

×60=30

o

Now,

∠AOP=∠BOC+∠COP

∠AOP=60+30

∠AOP=90

o

Hence justified.

=> -7+3x=3/7×3

=> -7+3x=9/7

=>3x=9/7+7

=>3x=58/7

=>x=58/7×1/3=58/21
