Select all the distribution shapes for which it is most often appropriate to use the mean .
goblinko [34]

The distribution shape that tells us for which it is best to use the mean is the skewed.

<h3>What is the mean?</h3>

This is the term that is used to refer to the average score that exists in a data set.

In the question, these are the reasons why the other options are not correct

When we say Bimodal we are talking about the 2 modes that are in a symmetric distribution. This has nothing to do with the mean

The bell shape has to do with how the normal distribution is when it is drawn. It would create a bell shape hence the mean is not useful.

symmetric has to do with the fact that there are mirror images when the vertical line is drawn in the distribution.

Uniformed shapes tells us that the classes are made up of the same frequency all through.

The skewed shape is what tells us if the median is more or if it is less.

Hence we have the answer that the distribution shapes for which it is most often appropriate to use the mean is the skewed.

How do I figure this out ? Please help me
victus00 [196]
Ahh, the ol' trick word problems.

Okay so lets break this down.

So we have 7,000 square feet of work that must be done.  We can lose the square feet part as it will only interfere with solving the problem.

So lets say we have 7,000 amount of work that needs to be done.

We know that our company can get 35 work done in one hour.  Our company also works 10 hours per day so we can say we get 350 work done per day.

We need to figure out how much of the work we got done in four days so we can multiply it by 4 and get 1400 work in four days.

1400/7000 work has been complete.  Lets simplify this.

14/70 work has been completed.

Now we need to find the percent using our good friend ratios.

14/70 = x/100

Then we use cross multiplication to solve and we get 20/100.

We have 20% of the work done.

Pro Tip: In real life, you can assume that when you are at 20% work done that it wont actually be 20% because your boss will want you to be done within 12 days.  In real life, you would have 60% of it done and on to the next project!

Whats negative one squared
Anni [7]

Answer:

(-1)^2 = +1

Step-by-step explanation:

6 (y-8)=6 <br><br><br><br> I think it’s 9 I’m not sure
Triss [41]

Answer:

y = 9

Step-by-step explanation:

6 (y-8)=6

Divide each side by 6

6/6 (y-8)=6/6

y-8 = 1

Add 8 to each side

y-8+8 = 1+8

y = 9
