The mean of the set of data 9,5,9,5,5,13,m and n is 8. a) calculate the value of m+n
b) hence, Find the mode of the set of data if
(i) m = n
(ii) m ≠ n

To find the mean of a data set, add all the values together and divide by the number of values in the set. The result is your mean!

Step-by-step explanation:

hehehe i hope its correct

a) 9+9=18

b) 9

Step-by-step explanation:

do your own work and don"t cheat.

step-by-step explanation:

shell's the art director at her local community center. she paid $10 and for each child that attends she earns $4.

for each child she ears $4 that is the slope m = 4

she paid $10, that is the initial amount paid. so 10 is the y intercept b

m =4   and b = 10

y intercept is 10 so the point is (0,10)

we start graph from y intercept (0,10)

slope = 4 . we know slope = rise / run

slope = 4   or 4/1   are same

rise = 4   and run = 1

for rise we move 4 units up and for run we move 1 unit to the right

the graph is attached below

x axis is the number of child she attends

y axis is the amount   she earns
