Answer with explanation:

It is given that number cube that is having number from (1 to 6) is rolled hundred times.

From the table it can be seen that,

→2 = 18 times

→ 4= 11 times

→6 = 21 times

→P = Probability

P(2)=\frac{18}{100}\\\\P(4)=\frac{11}{100}\\\\P(6)=\frac{21}{100}

 ⇒ P(Even Number)

          =P(2) + P(4) +P(6)\\\\=\frac{18}{100}+\frac{11}{100}+\frac{21}{100}\\\\=\frac{50}{100}\\\\=\frac{1}{2}

Required Probability in terms of Percentage

           =\frac{1}{2} \times 100\\\\=50

    = 50%  

Option A

The answer is 50% because to find the probability of 3/6 which is the even numbers that add up to 50 so 3/6 is equal to 1/2 and 1/2 of 100 is 50

so your answer is 50%

Consider the function f given by f(x)=x*(e^(-x^2)) for all real numbers x.
NISA [10]

Answer:

\frac{\sqrt{\pi}}{4}

Step-by-step explanation:

You are going to integrate the following function:

g(x)=x*f(x)=x*xe^{-x^2}=x^2e^{-x^2}  (1)

furthermore, you know that:

\int_0^{\infty}e^{-x^2}=\frac{\sqrt{\pi}}{2}

lets call to this integral, the integral Io.

for a general form of I you have In:

I_n=\int_0^{\infty}x^ne^{-ax^2}dx

furthermore you use the fact that:

I_n=-\frac{\partial I_{n-2}}{\partial a}

by using this last expression in an iterative way you obtain the following:

\int_0^{\infty}x^{2s}e^{-ax^2}dx=\frac{(2s-1)!!}{2^{s+1}a^s}\sqrt{\frac{\pi}{a}} (2)

with n=2s a even number

for s=1 you have n=2, that is, the function g(x). By using the equation (2) (with a = 1) you finally obtain:

\int_0^{\infty}x^2e^{-x^2}dx=\frac{(2(1)-1)!}{2^{1+1}(1^1)}\sqrt{\pi}=\frac{\sqrt{\pi}}{4}
