So to find the answer of the area, you have to multiply 7 and 8 which would equal to 56.
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:
6 5/12
Step-by-step explanation:
Given the expression :
4 2/3 + 1 3/4
The sum of the numbers :
4 2/3 + 1 3/4
14/3 + 7/4
L.C.M of 3 and 4 = 12
(56 + 21) / 12
77 / 12
= 6 5/12
