47.60 + 0.20(47.60) = 47.60 + 9.52 = 57.12
OR
47.60(1.20) = 57.12
Alike: They both find what's in common.
Difference: LCM finds the least multiple while GCF finds the greatest factor.

Answer:
156
Step-by-step explanation:
Given the data:
Age (X) :
38
41
45
48
51
53
57
61
65
Pressure(Y) :
116
120
123
131
142
145
148
150
152
From the data, we could obtain a regression equation to mod the data Given using a linear regression calculator :
The regression equation obtained is :
y = 1.48769X + 60.46103
Using the model, the predicted blood pressure for a person aged 64 will be :
y = 1.48769(64) + 60.46103
y = 95.21216 + 60.46103
y = 155.67319
y = 156 (nearest whole number)
The median is 48 because it is the biggest number and the biggest number is the median
