Statisticians use summary measures to describe the amount of variability or spread in a set of data. The most common measures of variability are the range, theinterquartile<span> range (</span>IQR<span>), </span>variance<span>, and standard deviation. This is from google btw</span>
Answer:
The question is asking which combinations of make different types of equations. y=2x^2 makes a quadratic equation, y=-4x+1 makes a linear equation, and y=1 makes a horizontal line
C is incorrect since the Y-intercept hits the y axis at (0,12) so it can't be possible to hit (5,12)
Six subtracted from three times a number the difference is twice the number in standard form is....
3x - 6 = 2x

<span> For this case we have the following system of equations:
</span>
<span>
Where,
x: time in hours walking
Y: time in hours on the bus
We solve the system of equations.
Rewriting the system we have:
</span>
<span> Adding both equations we have:
</span>
<span> Clearing x we have:
</span>
