-15x=-4x... How to move the x to the left?
Delvig [45]
-15x=-4x

We know that adding zero wouldn’t change the value

-15x=-4x+0

Now we can add 4x (since that’s the opposite of the negative sign) to the other side

-11x=0

0 divided by 11 is 0

x=0

What is the value of the interquartile range of the data below?<br> 6<br> 12<br> 14<br> 24
Strike441 [17]

Answer:

14

Step-by-step explanation:

The interquartile range is the value of quartile 3 minus quartile 1.

The "box" part of this diagram has 3 lines, the left most, the middle, and the rightmost.

The leftmost line is Quartile 1. The right most is Quartile 3.

Hence

interquartile range = quartile 3 - quartile 1

Looking at the box plot, we can see that each small line in the number line is 2 units.

The leftmost line (quartile 1 ) is at 1 unit left of 30, so that is 30 -2 = 28

The rightmost line (quartile 3) is at  1 unit right of 40, so that is 40 + 2 = 42

Hence,

Interquartile range = 42 - 28 = 14

Integral of 1/(x^2-x+1) ​
Lunna [17]

\boxed{\sf \displaystyle{\int}x^ndx=\dfrac{x^{n+1}}{n+1}}

\\ \sf\longmapsto \displaystyle{\int}\dfrac{1}{x^2-x+1}

\\ \sf\longmapsto \displaystyle{\int}x^{-2}-x^{-1}+1

\\ \sf\longmapsto \displaystyle{\int}x^{-2}-\displaystyle{\int}x^{-1}+\displaystyle{\int}1

\\ \sf\longmapsto \dfrac{x^{-2+1}}{-2+1}-\dfrac{x^{-1+1}}{-1+1}+1

\\ \sf\longmapsto \dfrac{x^{-1}}{-1}-\dfrac{x^0}{0}+1

\\ \sf\longmapsto -\dfrac{1}{x}-\dfrac{1}{0}+1

\\ \sf\longmapsto -\dfrac{1}{x}-\infty+1

\\ \sf\longmapsto \infty
