(1 point)
mean: 8.8, median: 9, mode: 9, range: 10
mean; 8.8, median: 9, mode: 9, range: 5
mean: 13.8, median: 14, mode: 14, range: 5
mean: 13.8, median: 14, mode: 14, range: 10

Answer 1

Sum of all numbers/ frequency = mean
(99+ 86+76+ 95+ x)/5 = 91
x = ???

Answer 2

4. A) x.91
B)x.87
c)x.82
d)x.99

Answer 3

for the second question solve the equation
4* 35 = 31.7 + 42.8 + 26.4 + x

Answer 4

maddi i hate school too

Answer 5

5. A)x=39.1
B)x=42.6
C)x=40.5
D)x=
36.8

Answer 6

Answer 7

6. Find the mean, median, mode, and range of the data set aĀer you perform the given operation on each

mean: 13.8, median: 14, mode: 14, range: 5
mean: 13.8, median: 14, mode: 14, range: 10

Answer 8

to get the median first arrange the numbers in ascending order
the median is the middle number in the list.

Answer 9

i dont get the add 5, is it just like +5 at the end thats whats confusing me

Answer 10

yes just add 5 to the list so we gat
9 7 12 9 13 3 5 7 numbers

maybe you have to add 5 to each of the values

Answer 20

that would make the list
8,12,14,14,17,18

yea thats what it is

Answer 21

the median of this is 14 . also the mode ( the most frequent occurring number) is also 14

Answer 22

can you work out the mean and the range?

Answer 23

i thnk so

Answer 24

the range is highest number - lowest number

Answer 25

so 10

Answer 26

yea

Answer 27

so 10
