Molodets [167]

Answer: $60,540< \mu$

Step-by-step explanation:

The confidence interval for population mean is given by :-

$\overline{x}-z^*\dfrac{\sigma}{\sqrt{n}}< \mu$

, where $\sigma$ = Population standard deviation.

n= sample size

$\overline{x}$ = Sample mean

z* = Critical z-value .

Given : $\sigma=\$17,000$

n= 49

$\overline{x}= \$65,300$

Two-tailed critical value for 95% confidence interval = $z^*=1.960$

Then, the 95% confidence interval would be :-

$65,300-(1.96)\dfrac{17000}{\sqrt{49}}< \mu$

$=65,300-(1.96)\dfrac{17000}{7}< \mu$

$=65,300-4760< \mu$

$=60,540< \mu$

Hence, the 95% confidence interval for estimating the population mean $(\mu)$ :

$60,540< \mu$

ΔABC was dilated from point A to get ΔADE. Find the length of AD given a scale factor of 4.

rewona [7]

Since triangle ADE is similar to triangle ABC and the scale factor is 2, the following relation must be fulfilled:

$\frac{AD}{AB}=4$

The, by substituting the given information, we have

$\begin{gathered} \frac{6x-8}{x+2}=4 \\ \end{gathered}$

By multiplying both sides by x+2, we get

$6x-8=4(x+2)$

which gives

$6x-8=4x+8$

Then, by subtracting 4x to both sides, we have

$2x-8=8$

and by adding 8 to both sides, we obtain

$2x=16$

then, x is given by

$x=\frac{16}{2}=8$

Then, by substitutn
