Answer: About 4 points should be below the trend line.

Step-by-step explanation: A Scatter Plot has points that shows the relationship between two sets of data.

A line of best fit or trend line is a straight line that best represents the data on a scatter plot.  

This line may pass through some of the points, none of the points, or all of the points.

But its objective is to have the line as close as possible to all points, and as many points above the line as below.

As there are 4 points above the trend line, so there should be 4 points below that.

If a+1,2a+1,4a-1 are in A.P, then the value of a is
Digiron [165]

Answer:

a = 2

Step-by-step explanation:

In an AP  the difference between consecutive terms is common (equal), thus

t₂ - t₁ = t₃ - t₂ , that is

2a + 1 - (a + 1) = 4a - 1 - (2a + 1) ← distribute and simplify both sides

2a + 1 - a - 1 = 4a - 1 - 2a - 1

a = 2a - 2 ( subtract 2a from both sides )

- a = - 2 ( multiply both sides by - 1 )

a = 2

Why do I think I'm ugly
Tanya [424]

Answer:

Ok listen here

Step-by-step explanation:

You are like the earth.

On the inside is a bright center and lava. When lava comes to the surface as a volcano, many people think it's ugly and dangerous, but other people think that it's beautiful.

We all know that a lot of people think the surface of the earth is ugly, and they have given up hope that people can change it, but the truth is that, the world is beautiful and we can change it.

You are beautiful and the people on your earth are represented as your brain. Your brain needs to tell you to look at yourself and to say that you are beautiful. You can change your mindset to tell you that you don't care what other people say, all that matters is what you say.

Always remember that :)
