Need help on number 22 I really need help!!!!!!!!! If u can help on 23 that would be awesome!!!!!

22. If you add a number to a series of data, and it doesn't change the mean, that number MUST equal the mean. Try adding the mean number into it, hopefully it doesn't change the mode or median either.

23. Basically I think (can't quite read all the question!) just work out the circumference of a circle with radius 20 feet (urgh imperial), ie 2*pi*r so 40pi.

22.
mode=the number that occurs most in the set of numbers
median=if the number are in increasing order, the number in then middle
mean=average or if all the number are added together and divided by the number of numbers, you get the average, exg mean of 2,3,4=(2+3+4)/3=9/3=3

the numbers are
91,93,93,95,98,100
mode, the number that occurs most is 93
mediann, there are 6 numbers so there is no middle number
we must fix that
first find teh mean
91+93+93+95+98+100 divide by6=95
therefor the mean is 95
the easiest way to make the mean meadian and mode the same is add 2 more 95's into the order

91,93,93,95,95,95,98,100
mode=number occurs most=95
median=middle number=95
mean=91,93,93,95,95,95,98,100 added tother and divided by 9=95

the order is 91,93,93,95,95,95,98,100

23. so the circle that he can walk around, is representing the circumference of the circle
20 is the radius
circumference=2 times pi times raidus

c=2(pi)20
c=40pi
c= aprox125.664

the dog can walk 125.7 feet before returning to start

If 2 more violinists join the orchestra and 1/2 the orchestra are violinists already what fraction of all musicians would play a stringed instrument

Answers

So, if we have 100 people in the orchestra- 50 of them are violinists.
If two more violinists join the orchestra, there would be 102 players and 52 violinists.
52/102 is the fraction you are looking for. Simplified it would be 26/51.

Hope this helps!

The answer is 52/ 102, when simplified..
26/51. Hope it helps! :)

Find the slope of the line through each pair of points (19, -16), (-7,-15)

Answers

equation: $( y_(2)-y_(1) )/(x_(2)-x_(1))$
plug the numbers into the equation:
((-15) - (-16)) / (-7) - (19)
(-15+16) / (-7-19)
1 / -28

The answer is -1/28
