The table shows the number of minutes Garrett practiced his trombone each week in one month. Week Number of Minutes Practiced 1

vredina [299]

Answer:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week 1 2 3 4

Minutes 190 163 327 205

For this case we can find the mean with the following formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

What is the slope of the line represents by 5x-12y=24 -2 24/5 -12 5/12 How do you get the answer? Please epxlain

mrs_skeptik [129]

5x - 12y = 24 - it's a standard form of equation of a line

The slope-intercept form: y = mx + b

m - slope

b - y-intercept.

Convert the standard form to the slope-intercept form:

$5x - 12y = 24$ <em>subtract 5x from both sides</em>

$-12y=-5x+24$ <em>divide both sides by (-12)</em>

$y=\dfrac{5}{12}x-2$

Answer: $\boxed{\dfrac{5}{12}}$
