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.

zlopas [31]

Answer:

Kindly check explanation

Step-by-step explanation:

A.)

The problem with the here is that we might have introduced bias into our sample by failing to randomize the assignment of gender. By pacing the male gender in the treatment group and females into the control group, this might spring up a spurious association in our experiment as a result of a possible confounding variable, gender. Therefore, assignment of subject shouldn't be on the basis of gender.

2.)

Using a coin toss in placing subjects into groups will give a good random assignment, however, since only ten subjects are available and of which 5 will be placed into each group, there is no certainty that there will be equal number of heads and tails during the 10 flips. Alternatively, a random selection of the name of the 10 subjects could be chosen from a raffle.

3.)

Each batch of rat might be homogenous and hence will affect our experiment and definitely our conclusion. It would be best to assign rats from each batch to all treatment groups in other to obtain a good random design

Solve the Equation.
IgorLugansk [536]
<h2>1.</h2>

Firstly, combine like terms: 7r-8=10+r

Next, subtract r on both sides of the equation: 6r-8=10

Next, add 8 onto both sides of the equation: 6r=18

Lastly, divide both sides by 6 and <em><u>your answer will be r = 3.</u></em>

<h2>2.</h2>

Firstly, multiply both sides by e: TE=3u

Lastly, divide both sides by 3, and <em><u>your answer will be \frac{TE}{3}=u</u></em>

What you do is you “take apart” the net so it has individual rectangles, then you multiply the 2 sides... you do that for each rectangle then add it all up
