Answer:
Step-by-step explanation:
sum of xf= 54+5p
sum of f=12+p
therefore mean = sum of xf/sum of f
=54+5p/12+p
12+p=54+5p
54-12+5p-p=0
42+4p=0
4p=-42
p=42/4=10.5
then mean =54+52.5/12+10.5
=106.5/22.5
=4.7333=4.8
therefore mean =4.8

pls mark me the brainliest
pls mark me the brainliest..
from where 52.5come
we found that p=10.5 so we substitute in sum of xf and sum of f to get 52.5
