Derive the mean, variance and MGF of Binomial distribution

Answer»

Answer:

CALCULATION of the Mean

In order to FIND the mean and variance, you'll need to know both M'(0) and M''(0). BEGIN by calculating your DERIVATIVES, and then evaluate each of them at t = 0. ... From this, you can calculate the mean of the probability DISTRIBUTION. M(0) = n(pe0)[(1 – p) + pe0]n - 1 = np

The numerator of fraction is less3 than its denominator is less than numenator 29/20

Answer»

Hey buddy hope this finds u WELL ALSO mark me brainliest


Let the denominator be x
            Numerator  is x-3
The fraction is (x-3)/x
when 2 is added to numerator and denominator
                                 we have fraction as (x-1)/(x+2) 
ATQ  (x-3)/x +(x-1)/(x+2)= 29/20
   ⇒    (x-3)((x+2) +x(x-1)=x(x+2)*29/20
   ⇒    (x²-6-x + x²-x)20= 29x²+58x
   ⇒    40x²-120-40x=29x²+58x
   ⇒    11x²-98x- 120=0
   ⇒    11x² - 110x +12X -120=0
   ⇒     (11x+12)(x-10)=0
Canceling the negative fraction value  of x we have x=10
Then the fraction (x-3)/x=7/10

Find the difference between the compound interest and the simple interest on rupees 30000 at 7% per .A for 3 years.

Answer»

ANSWER:

Principal=30,000 Rs.

C.I=4347 Rs.

Rate of interest=7 %

Amount=Principal+C.I

Amount=30,000+4347=34347Rs.

Let the TIME is T YEARS' then

⇒34347=30000(1+ 7/100)T

⇒34347=30000(107/100)T

⇒(107/100)T=34347/30000

⇒(107/100)T=11449/10000

⇒(107/100)T=(107/100)2

T=2years

A person got 45% marks in an exam and failed to qualify for the next round by 12 marks. Another person got 54% marks in the same exam and cleared the qualifying marks by 10.5 marks. Find the maximum marks that can be obtained in the exam?​

Answer»

Answer:250

Step-by-step explanation:

Let the total MARKS be x

Therefore, passing marks = 45x/100 +12

Or passing marks = 54X/100 -10.5

Therefore, 45x+1200/100 = 54x-1050/100

45x + 120 = 54x -105

1200+1050= 54x-45x

2250= 9x

x = 2250/9

x = 250

In a three-phase unbalanced load, how the instantaneous negative-and positive-sequence currents canbe extracted?​

Answer»

Answer:

Alternators can be subjected to UNEQUAL phase loading, but this will RESULT in unequal phase

voltages. Employing a three phase sensing AVR will always ensure the best possible overall

voltage REGULATION and will always be nominated if an alternator is to be used to supply power

to MULTIPLE loads where an unbalanced load condition may arise. For further information and

A concave mirror of focal length 18 cm forms an erect image, three times the size of the object, how far is the object from the mirror?​

Answer»

Answer:

12 cm

Step-by-step explanation:

GIVEN there is a concave MIRROR.

Focal length, f = -18 cm

Also, it's given that, it forms an erect image, three TIMES the size of object.

Therefore, it will be a virtual image.

Therefore, we will get,

Object distance, u = -ve

Image distance, v = +ve

Now, we have,

Magnification, m = 3

But, we know that,

m = -v/u

Therefore, we will get,

=> -v/u = 3

=> v = - 3u

=> v = - 3u

Now, we know the mirror formula, i.e.,

1/u + 1/v = 1/f

Substituting the values, we get,

=> 1/u - 1/3u = -1/18

=> 3/3u - 1/3u = -1/18

=> (3-1)/3u = -1/18

=> 2/3u = -1/18

=> 3u/2 = -18

=> 3u = -18 × 2

=> 3u = -36

=> u = -36/3

=> u = -12

Therefore, we have,

=> v = -3(-12)

=> v = 36

Hence, the object is at a distance of 12 cm from the mirror.
