sergij07 [2.7K]

Answer:

a) sample size is 40

Step-by-step explanation:

(a)

$\sigma=4$ minutes

Margin of error, E is 75 seconds E=75/60= 1.25 minutes.

The level of significance $\alpha= 0.05$ for 95% level of significance

For 95% confidence interval $z_{\frac{\alpha}{2}}=1.96$ from standard deviation table

Sample size required, n

$n=\left (\frac{z_{\frac{\alpha}{2}}\cdot \sigma}{E} \right )^{2}=\left (\frac{1.96\cdot4}{75/60} \right )^{2}=39.337984$

Rounding off, n=40

Sample size =40

Find the measure of ∠P

Blizzard [7]

Triangles internal angles will always equal 180 degrees.

So, with that being said we can add up the known angles and subtract them from 180 to get our missing angle

28+67 = 95
180-95 = 85
so angle P is 85 degrees

Answer:

$x = \dfrac{-\log 7}{\log 7 - \log 2}$

Step-by-step explanation:

$2^x = 7^{x + 1}$

Take the log of both sides.

$\log 2^x = \log 7^{x + 1}$

Use properties of log.

$x \log 2 = (x + 1) \log 7$

$x \log 2 = x \log 7 + \log 7$

$x \log 2 - x \log 7 = \log 7$

$x(\log 2 - \log 7) = \log 7$

$x = \dfrac{\log 7}{\log 2 - \log 7}$

$x = \dfrac{\log 7}{-(\log 7 - \log 2)}$

$x = \dfrac{-\log 7}{\log 7 - \log 2}$
