Solve for r<br><br>v = 4/3 r^3<br>​
sergejj [24]

Answer:

r=\sqrt[3]{\frac{3v}{4} }

Step-by-step explanation:

To solve for r:

v=\frac{4}{3}r^{3} (given)

\frac{3v}{4}=r^{3} (times \frac{3}{4} on both sides)

r=\sqrt[3]{\frac{3v}{4} }

I hope this helps :)

The data shows the speed, in miles per hour, of motorists on a stretch of road.
melomori [17]

Answer:

i. 18 miles per hour is an outlier

ii. the outlier decreases the mean speed

Step-by-step explanation:

An outlier in a given data is one of the values that is far greater or lesser compared to others. It affect the mean and standard deviation of a given data significantly.

From the given data, 18 is far too small compared to other values. This is certainly an outlier. This would affect the mean speed by decreasing the value.

An interquartile range is a measure of differences among data by dividing a set of given data into quartile. Increasing the value of the outlier would increase the interquartile range.

The area of the 2 semicircles combined, which make a circle, are:

π*r², where r is 5

r²=25

π*25=78.53981633
