A person's metabolic rate is the rate at which the body consumes energy. Metabolic rate is important in studies of weight gain,
cupoosta [38]

Let m be mean

Mean= sum/ n

Mean= (1720+1687+1367+1614+1460+1867+1436) / 7

m= 11151 / 7

M= 1593

Mean= 1593

Standard deviation

|x-m|^2

For 1st: |1720-1593|^2=8836

For 2nd: |1687-1593|^2=10201

For 3rd: |1367-1593|^2=51076

For 4th: |1614-1593|^2=441

For 5th: |1460-1593|^2=1689

For 6th: |1867-1593|^2=75076

For 7th: |1436-1593|^2=24649

Summation of |x-m|^2 = 171968

Standard deviation sample formula is:

S.D = sqrt((summation of |x-m|^2) / n-1)

S.D=sqrt(171968/6)

S.D=sqrt(28661.33)

S.D=169.30

Standard deviation is 169.30

Which of the following expressions represents the GCF of 91x 2 y and 104xy 3?
zlopas [31]
The greatest common factor is found by finding the product of common primes.

91=7*13, 104=2*2*2*13  so the gcf of 91 and 104 is 13.  Since the highest power of x and y in both terms is 1, the hcf for the variables is just xy

13xy
