Answer:

a) Requires you to plot the point on the graph so you'll just have to plot (4,2600) using the graph

c) Here they have given the years as 3.5, using this inorder to determine our value we need to draw a straight line upwards from (3.5,0) and keep extending until it touches the graph.Then draw another line from the point where it touches horizontally toward the left until it cuts the yaxis and that will be your value answer

I hope it's clear I'm really sorry it's so hard to explain in words.

Btw if you could mark it as brainliest that would be great ^^

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.

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.

Hi there!

»»————-　★　————-««

I believe your answer is:

$x = 1$

»»————-　★　————-««

Here’s why:

⸻⸻⸻⸻

$\boxed{\text{Calculating the answer...}}\\\\\frac{x+3}{6}=\frac{2}{3}\\\----------\\\rightarrow (\frac{x+3}{6})6=(\frac{2}{3})6\\\\\rightarrow x + 3 = 4\\\\\rightarrow x + 3 - 3 = 4 - 3\\\\\rightarrow \boxed{x=1}$

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.

Answer:

The answer is "0.0023 and Choice a"

Step-by-step explanation:

In point a:

The central limit theorem:

$\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023$

In point b:

The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.
