Step-by-step explanation:
To take the average of the weight of the cat in the month of April is the following:
9.8 + 9.6 + 9.7 + 9.5 + 9.4 = 48
But then divide that by the number of samples:
48/5=9.6
The mean for April is 9.6
To take the average of the weight of the cat in the month of November is the following:
9.4 + 9.3 + 9.1 + 9.2 + 9 = 46
But then divide that by the number of samples:
46/5=9.2
Then, lastly, subtract the mean from November by the mean of April:
9.6-9.2=0.4

Answer:
s=6 years
m=48 years
Step-by-step explanation:
Let
Mother's age=m
Son's age=s
m=8*s
m=8s (1)
m+6=9/2(s+6)
m+6=9/2s+27 (2)
Substitute (1) into (2)
m+6=9/2(s)+27
8s+6=9/2s+27
8s+6-9/2s-27=0
8s-9/2s-21=0
(16-9/2)s-21=0
7/2s=21
s=21÷7/2
=21×2/7
=42/7
s=6
Present age of the son=6
m=8s
=8(6)
m=48
Present age of the mother=48
