Answer:

3/7

Step-by-step explanation:

To find the square root of a fraction, find the square root of the numerator and denominator individually

So, √9 = 3

√49 = 7

Put them back as a fraction = 3/7

Hope this helps

Answer:

3/7

Step-by-step explanation:

We want to find the square root of 9/49.

Remember that when we take the square root of a fraction, it's equal to taking the square root of each of the numerator and denominator.

Let's split this up into the numerator and denominator:

<u>Numerator</u>:

The numerator is 9, and we know that the square root of 9 is 3. This is because 3 * 3 = 9.

<u>Denominator</u>:

The denominator is 49, and we know the square root of 49 is 7 because 7 * 7 = 49.

Thus, we have:

\sqrt{\frac{9}{49} } =\frac{\sqrt{9} }{\sqrt{49} } =3/7

The answer is hence 3/7.

What is 3 ln 3 - ln 9 expressed as a single natural logarithm

Since ln (m^n) = n⋅ln (m)                 … natural logarithmic property
We can further simplify the expression 3 ln 3
3 In 3 = In (3^3)
Therefore, 3 ln 3 - ln 9 = In (3^3) – In 9

Since ln(m/n) =ln(m) – ln(n)         … natural logarithmic property
We can further simplify the expression In (3^3) – In 9
In (3^3) – In 9 = In [(3^3)/(9)]
= In (27/9)
= In 3

Therefore, 3 ln 3 - ln 9 expressed as a single natural logarithm is In 3.

Question 4 options: Find the mean and standard deviation for a binomial distribution with 680 trials and a probability of succes
lys-0071 [83]

Answer:

Mean for a binomial distribution = 374

Standard deviation for a binomial distribution = 12.97

Step-by-step explanation:

We are given a binomial distribution with 680 trials and a probability of success of 0.55.

The above situation can be represented through Binomial distribution;

P(X=r) = \binom{n}{r}p^{r} (1-p)^{n-r} ; x = 0,1,2,3,.....

where, n = number of trials (samples) taken = 680 trials

            r = number of success  

           p = probability of success which in our question is 0.55

So, it means X <em>~ </em>Binom(n=680, p=0.55)

<em><u>Now, we have to find the mean and standard deviation of the given binomial distribution.</u></em>

  • Mean of Binomial Distribution is given by;

                    E(X) = n \times p

       So, E(X) = 680 \times 0.55 = 374

  • Standard deviation of Binomial Distribution is given by;

                   S.D.(X) = \sqrt{n \times p \times (1-p)}

                               = \sqrt{680 \times 0.55 \times (1-0.55)}

                               = \sqrt{680 \times 0.55 \times 0.45} = 12.97

Therefore, Mean and standard deviation for binomial distribution is 374 and 12.97 respectively.
