\\ \sf\longmapsto tan40=\dfrac{P}{430}

\\ \sf\longmapsto 0.83=\dfrac{P}{430}

\\ \sf\longmapsto P=430(0.83)

\\ \sf\longmapsto P\approx361m

  • P=Height of tower

Answer:

\displaystyle 361\:m.

Step-by-step explanation:

You would set your proportion up as so:

\displaystyle \frac{430}{h} = cot\:40° → 430 = hcot\: 40° → \frac{430}{cot\: 40°} = h → 360,8128414... = h \\ \\ 361 ≈ h

So, the height of the clock tower is <em>approximately</em><em> </em>361 metres.

According to a​ report, 67.5​% of murders are committed with a firearm. ​(a) If 200 murders are randomly​ selected, how many wou
kolezko [41]

Answer: The answer is 135 murders.

Step-by-step explanation: The report tells us that statistically 67.5% of murders are committed using a firearm. It follows therefore that in a sample of 200 randomly selected murders, one would expect that 67.5% of those would be by a firearm. \frac{67.5}{100} * 200 = 135.

It would certainly be higher that the expected value based on previous data collected but it would not be unusual because one sample may have a higher than "normal" amount of murders by firearm. Statistics aren't going to be exact for every sample.
