Answer:
Step-by-step explanation:
a₂ = 9
a₃ = a₂-1.5
a₄ = a₃-1.5
a₅ = a₄-1.5
etc.
The terms have a common difference of -1.5, so the sequence is arithmetic.
Here, Rational numbers are: = 2/9 and √225
& other two are irrational
Hope this helps!
Answer:
Yes, it is a matched pairs design.
Step-by-step explanation:
Assuming that the twins used in the experiment are identical, this can be treated as a matched pairs designed.

Answer:
481
Step-by-step explanation:
Lets say width = x
Length = x+24
Perimeter is 100 so
100=x+24+x+24+x+x
100=4x+48
100-48=4x
52=4x
x=13
So width = 13
Length = 37
37x13=481
