PLZZZZ ANSWER ASAP I WILL GIVE BRAINLIEST BUT WILL MAKE SUREIT IS RIGHT FIRST!!!!!!!!!!!!!!!!!!!! Which expression is equivalent

irakobra [83]

Answer:

The correct option is 1/4^2

Step-by-step explanation:

The given expression is:

4^6 * 4^-8

According to the same base rule if the exponents have the same base then the exponents will be added.

If we look at the given expression both the values have the same base.

Therefore we will add the exponents of the value.

= 4^6+(-8)

= 4^6-8

= 4^-2

Now to change the negative exponent into positive we will take it to the denominator.

4^-2 = 1/4^2

Thus the correct option is A....

Suppose a marketing company wants to determine the current proportion of customers who click on ads on their smartphones. It was

andrezito [222]

Answer:

The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

$n = 100, p = 0.42$

92% confidence level

So $\alpha = 0.08$ , z is the value of Z that has a pvalue of $1 - \frac{0.08}{2} = 0.96$ , so $Z = 1.75$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 1.75\sqrt{\frac{0.42*0.58}{100}} = 0.3336$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.42 - 1.75\sqrt{\frac{0.42*0.58}{100}} = 0.5064$

The 92% confidence interval for the true proportion of customers who click on ads on their smartphones is (0.3336, 0.5064).
