The length of the circle - <span>the product of the diameter and the number Pi
l = d</span>π
l = 900cm
π ≈ 3,1415 przyjmiemy wartość 3
900cm = d* 3   [:3
d = 300cm  
<span>Becky rounded value of Pi , hence the difference in result
</span>
<span>More accurate calculation
</span>
l = d*π
900cm = d*3,1415
d = 900cm : 3,1415 = 286,49cm

<span>Becky overestimated the outcome</span>

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?
stiks02 [169]

Answer:

<h2>35x - 35y + 21</h2>

solution,

0.5(20x - 50y + 36) - 0.25( - 100x + 40y - 12) \\  = 10x - 25y + 18  + 25x - 10y + 3 \\

Combine the like terms:

= 10x + 25x - 25y - 10y + 18 + 3 \\

Simplify:

35x - 35y + 21

Hope this helps...

Good luck on your assignment...

stepladder [879]

Answer:

The outlier is $12, results in a decrease in the mean. Outliers have little influence on the median.

If you actually calculate and try and find an outlier, this dataset doesn't have one. But I'm going to assume they're just looking for an extreme number in the set since it clearly says to identify it
