Answer:

$\boxed{\sf \dfrac{41}{63}}$

Step-by-step explanation:

hi, it means that we have to compute

$\dfrac{2}{9}+\dfrac{3}{7}=\dfrac{7*2+3*9}{7*9}=\dfrac{14+27}{7*9}=\dfrac{41}{63}$

Answer:

$\frac{41}{63}$

Step-by-step explanation:

=> x+y

Putting x = $\frac{2}{9}$ ; y = $\frac{3}{7}$

=> $\frac{2}{9} +\frac{3}{7}$

LCM = 63

This will make the expression

=> $\frac{14+27}{63}$

=> $\frac{41}{63}$

This is the required factorized form

Use PEMDAS.

Parenthesis first.

(-15)-(-12)+3-(-9)

Next multiply,

(-15)+12+3+9 (two negatives get you a positive)

Finally, add and subtract:
-15+24=9

You get 9 as your answer.

Hope this helps!

Answer:

$\mu_{x}=np$

$\sigma^2_{X}=np(1-p)$

Step-by-step explanation:

∵ When x is a random variable having distribution B(n, p), then for sufficiently large value of n, the following random variable has a standard normal distribution,

$\frac{x-\mu}{\sigma}\sim N(0,1)$
