Answer:
Step-by-step explanation:
P = 2(l +w)
Let width be x
Length = x + 13
P = 38
38 = 2(x + 13 + x)
38 = 2(2x + 13)
38 = 2x + 26
2x = 38 - 26
2x = 12
x = 12/2
x = 6unit
Width = 6units
Length = x + 13 = 6+13 = 19units
12i is the answer to this
Answer:
36
Step-by-step explanation:
Data provided in the question:
Standard error = 1.5 minutes ( ∵ number are repetitive 1.51.5 )
Standard deviation = 9 minutes ( ∵ number are repetitive 99 )
Now,
Standard error = ( Standard deviation ) ÷ √n
Here,
n is the sample size
Therefore,
on substituting the respective values, we get
1.5 = 9 ÷ √n
or
√n = 9 ÷ 1.5
or
√n = 6
or
n = 6² = 36

Answer:
268.25
Step-by-step explanation:
by using the fact that one year is 365.25 days, we can subtract our 365.25 by our 97 to get 268.25, written in the equation of 365.25-97=268.25
*edit, messed up how long a year was, corrected my issue, answer & equation.
