Which expression is the simplest form of...

Lemur [1.5K]

Answer:

The answer is option A

Step-by-step explanation:

Using the rules of indices

That's

<h3> $( { {a}^{x} })^{y} = {a}^{x \times y}$ </h3>

Simplify the expression

We have

<h3> $( { {x}^{ - \frac{4}{7} } })^{7} = {x}^{ - \frac{4}{7} \times 7 } \\ = {x}^{ - 4}$ </h3>

Again using the rules of indices

That's

The final answer is

Hope this helps you

He takes a random sample of 49 recent charterholders and computes a mean salary of $172,000 with a standard deviation of $35,000

uysha [10]

Answer:

the 90% of confidence intervals for the average salary of a CFA charter holder

(1,63,775 , 1,80,000)

Step-by-step explanation:

<u>Explanation</u>:-

random sample of n = 49 recent charter holders

mean of sample (x⁻) = $172,000

standard deviation of sample( S) = $35,000

Level of significance α= 1.645

<u> 90% confidence interval</u>

$(x^{-} - Z_{\alpha } \frac{s}{\sqrt{n} } , x^{-} + Z_{\alpha } \frac{s}{\sqrt{n} })$

$(172000 - 1.645 \frac{35000}{\sqrt{49} } , 172000 +1.645 \frac{35000}{\sqrt{49} })$

on calculation , we get

(1,63,775 , 1,80,000)

The mean value lies between the 90% of confidence intervals

(1,63,775 , 1,80,000)
