Answer: There would be about 6 or 7 silk fibers per 300 yard length of silk fiber.
The problem states that each thread is made of about 3 to 10 silk fibers. The the problem as for a reasonable estimation of the number of silk fibers. It would be safe to assume that a reasonable estimation would be the average (or mean) of 3 to 10.
(3 + 10) / 2 = 6.5
Since 6.5 is the average, we could use 6 or 7 as a reasonable estimation.
Answer:
2 builder complete work = 155 days
Step-by-step explanation:
Given:
5 builder complete work = 62 days
So,
1 builder complete work = 62 days × 5
if,
2 builder complete work = [62 days × 5] / 2
2 builder complete work = 155 days
7pm the next day because 23 hours past 8:00pm would just drop one hour
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
Answer:
C and E
C) -(4)
E) -(4.001)
Remember to take into consideration the (-) in front of that x !
