2x + y = −3 −2y = 6 + 4x Write each equation in slope-intercept form.
Zanzabum

slope intercept form is y=mx+b

so solve for y


2x+y=-3

minus 2x both sides

y=-2x-3


-2y=6+4x

divide both sides by -2

y=-3-2x

y=-2x-3

For skewed data displays, the median is often a better esitmate of the center of distribution than the mean, but
bazaltina [42]

For skewed data displays, the median is often a better estimate of the center of distribution than the mean because the former is unaffected by large numbers.

<h3>What is mean?</h3>

Mean refers to the average of set of two or more numbers.

Mean of a set having 'n'  numbers = \frac{Sum Of 'n' Numbers}{n}

<h3>What is median?</h3>

Median refers to the middle-most value of a list of numbers, arranged either in ascending or descending order.

Median = \left \{ {{\frac{n}{2}^{th}  term, if n = even } \atop( (\frac{n-1}{2}+\frac{n+1}{2})/2)^{th} term, if n = odd   }} \right.

Now,

  • Since it takes the average of all the values in the data set, the mean is the most widely used measure of central tendency.
  • Because it is unaffected by exceptionally big numbers, the median performs better than the mean when analyzing data from skewed distributions.

Hence, For skewed data displays, the median is often a better estimate of the center of distribution than the mean.
