Answer: To add to the confusion, a lot of ladders aren't labeled properly. When recently shopping, I discovered that the advertised height on the ladders I was looking at was about 20% less than the actual practical height of the ladder. Beware the small print!

Also, no matter how safe you are, note that 24' is a LOT higher from above than below. :) I recently cleaned the gutters on the 3 storey side of my house. Never again.

Step-by-step explanation:Why would you BUY a ladder you will use but once? Go rent, even contractors rent ladders. The rental companies make sure their equipment is safe. They will advise you because your success means less insurance costs. I have a problem with a homeowner climbing this high, not experienced and without protection/harnesses. You need to rent a fire truck? They also rent boom trucks but one has to prove competence. Whatever you are trying to DIY there are limits and this is definitely one I would have insisted you get a professional. I doubt that your home owner's would cover a fall.

Voltage sags and swells. The power quality of a transformer is measured by the quality of the voltage. Two causes of poor power
zysi [14]

Answer:

a

 z-score = 1.57

b

 z-score_s = -3.36

Step-by-step explanation:

From the question we are told that

   The sample size is  n =  103  

    The  sample mean of  sag is  \= x_1 =  353

     The sample mean of swells is  \= x_2 =  184

    The standard deviation of  sag is  s_1  =  30

     The standard deviation of swells is  s_2  =  25

     The number of swell for a randomly selected transformer is  k  =  100

      The number of sag for a randomly selected transformer is  c  =  400

Generally the z-score for the number of swells is mathematically represented as

     z-score_s = \frac{ k - \= x_2}{s_2}

=>   z-score_s = \frac{ 100- 184}{25}

=>     z-score_s = -3.36

       

Generally the z-score for the number of sags is mathematically represented as    

      z-score = \frac{ c - \= x_1}{s_1}

     z-score = \frac{ 400 - 353}{30}

     z-score = 1.57
