Answer:
Mom=30 Daughter=6
Step-by-step explanation:
M=5×D
M+6=3×D
5D=3D-6
2D=6
D=12
M=12×3=36
Now: D=12-6=6
M=36-6=30
Problem:
The area of the patio of a relative's house is 20 square meters.
The width of the patio is 2 meters.
What is the length of the patio?
Solution:
The area is:
A = (w) * (l)
Where,
w: width
l: long
Clearing l we have:
l = A / w
Substituting values:
l = 20/2
l = 10 meters
I would say 18 because 790-610= 180 and 180÷10= 18

- Degrees of freedom is the number of values in the evaluation of a test statistic that are free to vary.
For t-statistic , the degree of freedom for a sample with sample size 'n' is given by :-

Given : Sample size : n-1
Then, the number of degrees of freedom the t-value will have :-

Hence, the t-value will have 14 degrees of freedom.
