First find the mean 0+1+1+2+5+9=18 18/6(Number of points in data set) =3 then check the distance of each number to the mean
3 and 0 = 3
3 and 1 = 2
3 and 1 = 2
3 and 2 = 1
3 and 5 = 2
3 and 9 = 6
then find the mean of those numbers so 3+2+2+1+2+6=16 16/6 = 2.66667(continuing)
So the answer in 2.66

Answer: The answer would be 2.6 but it says round up the tenths if needed so your answer would be 2.7. I took the same test and got it right. Have a nice day to whoever is reading this. :)

A positive real number is 1 more than another. When -2 times the smaller is added to the square of the larger, the result is 33.
Naya [18.7K]

Answer:

The smaller number is 4√2 and the larger number is (4√2 + 1).

Step-by-step explanation:

Let the two numbers be <em>x </em>and <em>y</em>, where <em>y</em> is the larger of the two numbers.

Since <em>y</em> is the larger number, it is one more than the smaller number. So:

y=x+1

When negative two times the smaller is added to the square of the larger, the result is 33. In other words:

-2x+y^2=33

Substitute:

-2x+(x+1)^2=33

Solve for <em>x</em>. Square:

-2x+(x^2+2x+1)=33

Simplify:

x^2+1=33

Subtract one from both sides:

x^2=32

And take the square root of both sides:

x=\pm\sqrt{32}=\pm 4\sqrt{2}

Since <em>y</em> is positive, we can ignore the negative case. So, the smaller number is:

x=4\sqrt{2}\approx5.66

And the larger number is:

y = 4\sqrt{2} + 1 \approx6.66

Step-by-step explanation:

If the purple rectangle were to get a transformation, then it would grow. For it to be similar it would be stretched one way to be as long as the green rectangle, but that's not how this works. Therefore, they are not similar.
