Answer:

9/4

Step-by-step explanation:

we know that 3median =2mean +mode

by converting given information...we get mean/median=9/11

again by converting we get the answer

Answer 2

Answer:

mode=15

median=11

mean=?

Step-by-step explanation:

mode=3median-2mean

15k=3(11k)-2(x) [took k because 15:11 is divided a common no. which i take as k]

15k=33k-2x

33k-15k=2x

18k=2x

9k=x   [9=mean]

mean/mode=9k/15k        [divided by 3 and k is common so canceled]

=3/5

3:5= answer

mark me brainlest pls
