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

Answer 1

Answer: 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.

Answer 2

Answer: 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

Clayton Road is 2.35 miles long. Wood Pike Road is 1.7 miles long. Draw a quick picture to find the combined length of Clayton Road and Wood Pike Road

Answers

Answer:

4.05 miles.

Step-by-step explanation:

See the attached diagram. (not in scale)

Let AB is the Clayton Road and its length is 2.35 miles and BC is the Wood Pike Road and it is 1.7 miles long.

So, the combined length of Clayton Road and Wood Pike Road is AC (= AB + BC)

So, the length of AC will be (2.35 +1.7) miles = 4.05 miles. (Answer)

Casey went to the fabric store and bought 2 2/3 yards of yellow fabric, yards of purple fabric, 3 1/9 and a pair of 5 1/5 inch scissors. How many yards of fabric did Casey buy altogether?

A.
5 7/9 yards

B.
5 5/9 yards

C.
5 5/3 yards

D.
5 1/3 yards

Answers

The answer is A: 5 7/9 yards

Final answer:

Casey bought a total of 5 5/9 yards of fabric (yellow and purple combined). The pair of scissors does not count towards the total yardage of fabric.

Explanation:

The first step is to add the amount of yellow and purple fabric that Casey bought. So we have 2 2/3 yards of yellow and 3 1/9 yards of purple fabric, which gives us a total of 5 5/9 yards of fabric (Since 2 2/3 equals 8/3 and 3 1/9 equals 28/9, when we add them we have 8/3 + 28/9 = 56/27, which simplifies to 5 5/9). The pair of scissors does not count towards the amount of fabric bought, so it can be disregarded for this question. Thus, the correct answer is B. 5 5/9 yards.
