4.

Three unbiased coins are tossed.What is the probability of getting exactly two heads.

Answer»

When 3 UNBIASED COINS are tossed, the sample space is {HHH, HTH, HHT, THH, THT, TTH, HTT, TTT] = 8

Event of getting two heads = {HTH, HHT, THH} = 3

P(Two Heads) = 3/8

Event of getting At least two heads (two or more than 2 heads) = {HHH, HTH, HHT, THH} = 4

P(At least Two Heads) = 4/8 = 1/2

Event of getting No heads = {TTT} = 1

P(No Heads) = 1/8

14.	Find the area of a triangle whose two sides are 18 cm and 10 cm and the perimeter is 42 cm.
Answer» Perimeter = Sum of all sides ➥ 42 = 18 + 10 + x (where x is the other side) ➟ 42 = 28 + x ⇢ x = 42 - 28 ⇒ x = 14 cm $\\$ Since we do not know the base and height of the TRIANGLE, we apply herons formula. $\\$ $\boxed{\sf{s = \dfrac{a + b + c}{2}}}\\\\$ $\sf{s = \dfrac{18+10+14}{2} = \dfrac{42}{2} = 21 cm}$ $\\$ Where; s is the semi-perimeter a, b, c are the sides of the triangle. $\\$ $\bf{Area = \sqrt{s(s-a)(s-b)(s-c)} }\\\\\\\implies \sf{Area = \sqrt{21(21-18)(21-10)(21-14)} }\\\\\\\implies \sf{Area = \sqrt{21(3)(11)(7)} }\\\\\\\implies \sf{Area = \sqrt{21 \times 21 \times 11}}\\\\\\\therefore \boxed{\underline{\bf{Area = 21 \sqrt{11} \: cm^{2}}}}$ $\\$ Know more: When base and height of a triangle are given, we can DIRECTLY USE the formula 1/2 × Base × Height.

14.

Find the area of a triangle whose two sides are 18 cm and 10 cm and the perimeter is 42 cm.

Answer»

Perimeter = Sum of all sides

➥ 42 = 18 + 10 + x (where x is the other side)

➟ 42 = 28 + x

⇢ x = 42 - 28

⇒ x = 14 cm

$\\$

Since we do not know the base and height of the TRIANGLE, we apply herons formula.

$\\$

$\boxed{\sf{s = \dfrac{a + b + c}{2}}}\\\\$

$\sf{s = \dfrac{18+10+14}{2} = \dfrac{42}{2} = 21 cm}$

$\\$

Where;

s is the semi-perimeter
a, b, c are the sides of the triangle.

$\\$

$\bf{Area = \sqrt{s(s-a)(s-b)(s-c)} }\\\\\\\implies \sf{Area = \sqrt{21(21-18)(21-10)(21-14)} }\\\\\\\implies \sf{Area = \sqrt{21(3)(11)(7)} }\\\\\\\implies \sf{Area = \sqrt{21 \times 21 \times 11}}\\\\\\\therefore \boxed{\underline{\bf{Area = 21 \sqrt{11} \: cm^{2}}}}$

When base and height of a triangle are given, we can DIRECTLY USE the formula 1/2 × Base × Height.

22.

Ram has purchased 22 lemons of rupees 1 And he sells 25 lemons of rupees 3 how much profil will ram get ?

Answer»

Answer:

Ans. is 20%

Here's solution

We KNOW that cost price(cp) of 2 lemons is 1 RS.

Now, he sells 5 lemons at 3 RS

So,

5 lemons =3 RS

2 lemons = X RS

By cross multiplying we get

5x= 6 & x=6/5

Therefore, Selling price(sp) of 2 lemons is 6/5 RS

Now Profit% = (sp-cp/cp) *100

=(6/5–1/5)*100

=1/5*100

=20%

So profit earned by seller is 20%

the universe gas law state that the volume (VM³) of a given mass of an ideal gas varies directly with it absolute temperature (TK) an inversely with it pressure (pM/ m²). A certain mass of gas at an absolute temperature 275K and pressure 10 N/ m² has volume 0.0224m³. find the formula that connect p, V, and T

Answer»

Step-by-step explanation:

Relationship between Pressure- Volume (Boyle's Law)

•The volume of a fixed mass of gas at constant temperature is inversely proportional to the pressure exerted on it.

•P ∞ 1 / V then PV equals a constant value.

•Boyle’s Law:

P1V1 = P2V2 at constant temperature.

Relationship between Temperature- Volume (Charles' Law)

•The volume of a fixed mass of gas at constant pressure is directly proportional to its absolute temperature (kelvin scale).

•V ∞ T then V / T equals a constant value.

•Charles’ Law:

V1 = V2 at constant pressure

T1 T2

Relationship between Volume-Mole (Avogadro's Law)

Avogadro postulated that EQUAL volumes of gases at the same temperature and pressure CONTAIN equal numbers of particles.

V ∞ n or V= kn where k is a constant.

MOLAR gas Volume

•Molar Gas Volume is the volume of 1 mole of a particular gas.

•It has been found experimentally that 1 mole of any gas at STP occupies a volume of 22.7 L.

•The molar volume of a gas at SLC is 24.8 L.

•Gas constants:

VSTP = 22.7 L

VSLC = 24.8 L

STP- 0 oC and 100kPa

SLC – 25 oC and 100KPa

There is a direct relationship between the number of MOLES of a gas and its molar volume.

n = V

Vm

Where:

n is the number of moles of gas

V is the actual volume of gas

Vm is the molar volume of the gas

•Combine Boyle’s and Charles’ Laws:

PV equals a constant value

V / T equals a constant value

to get PV / T equals a constant value.

•Combined Gas Law:

P1V1 = P2V2 for a constant amount of gas.

T1 T2

•P ∞ 1 / V (Boyle’s Law)

•P ∞ T (Gay Lussac’s Law)

•P ∞ n

•Combine these proportionalities:

P ∞ nT / V

Universal gas equation

•Replace proportionality with equality sign.

•Introduce a general gas constant, R and we get the general gas equation.

PV = nRT

where:

Pressure (P) is measured in kilopascals (kPa)

Volume (V) is measured in litres (L)

Temperature (T) is measured in kelvin (K)

Number of moles (n) – unit (mol)
