In the data set (0,-1);(-2,4);(-4,-8);(-1,5);(2,1);(3,-2);(-1,2)},which point is a possible outlier?

1 answer:

6 0

If it’s possible just graph:
Here you can see (-4,-8) is far away from the other points.

If you want a mathematical explanation basically look for trends in the data, and the rest of the points trend negative linear.

If you want to use formulas or equations there’s a very complicated one online, that is very difficult to understand.

Aaron found rhe length of the diagonal of a rectangle to be an irrational number. What could be the lenght of the diagonal

Amanda [17]

Answer:

See below

Step-by-step explanation:

It could be a positive square root l like √10 ( the number not being a perfect square).

He would have obtained this value from the application of the Pythagoras theorem. For example the length and width of the rectangle might have been 3 and 1 foot respectively, so the diagonal would have length √(3^2 + 1^2) = √10.

He could give an estimate of the length to nearest hundredth using his calculator. This would be 3.16 feet.

Consider the series 4 + 12 + 36 ... Find the sum of the first 9 terms.

jeyben [28]

Answer:

39364

Step-by-step explanation:

You can simplify the equation to make 4(1+3+9...) The nth term is therefore $3^{n-1}$ so u can substitute that into the equation so 4( $3^{n-1}+ 3^{n} + 3^{n+1}$ ..). This would simplify to 4( $3^0 +3+3^2$ + $3^3+3^4+3^5+3^6+3^7+3^8$ ). By simplifying this, you can make it so 4( $2^2+6^2+18^2+42^2+81^2$ ) = 4(4+36+324+2916+6561) =39364
