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
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.
First in your head multiply 8 by 7. this equals 56. now multiply 8 by 9 twice since there is two 9's. now you have two 72's. Add the 2's together from both 72's. now your numbers are 70, 70, 56 and 4. Add the four to your 5 which is now 96. split 96 between the 70's. not dividing just the two numbers. now you have 79, and 76. put together your numbers and your answer is 7976.
