Please solve this question?

Alchen [17]

Given,

$\lim_{x}^{a}\dfrac{x^{2/3}-a^{2/3}}{x-a}$

We can use L'Hopital's Rule to get,

$\lim_{x}^{a}\dfrac{2}{3-\sqrt[3]{x}}$

Now plug in a,

$\boxed{\dfrac{2}{3-\sqrt[3]{a}}}$

Hope this helps.

Step-by-step explanation:

The two base angles are congruent, so we have ...

x +17 = 4x -34

51 = 3x . . . . . . . add 34-x

17 = x . . . . . . . . .divide by 3

The standard deviation of a sample taken from population A is 17.6 for a sample of 25.

lawyer [7]

Answer:

The standard deviation of the sample mean differences is _5.23_

Step-by-step explanation:

We have a sample of a population A and a sample of a population B.

For the sample of population A, the standard deviation $\sigma_A$ is

$\sigma_A = 17.6$

The sample size $n_A$ is:

$n_A = 25$ .

For the sample of population B, the standard deviation $\sigma_B$ is

$\sigma_B = 21.2$

The sample size $n_B$ is:

$n_B = 30$ .

Then the standard deviation for the difference of means has the following form:

$\sigma=\sqrt{\frac{\sigma_A^2}{n_A}+\frac{\sigma_B^2}{n_B}}$

Finally

$\sigma=\sqrt{\frac{17.6^2}{25}+\frac{21.2^2}{30}}\\\\\sigma= 5.23$
