Answer:
⅖ m = 40 cm
Step-by-step explanation:
1 meter = 100 cm
1 : 100 = 2/5 : y
1 × y = 100 × 2/5
y = 40
Step-by-step Answer:
N=sample size = 200
sigma = population standard deviation = 1.2
s=Sample mean = 15.8
Best estimate of population mean = 15.8
standard error = sigma / sqrt(N)
= 1.2/sqrt(200)
= 0.08485
Therefore
estimate of population mean = 15.8 +/- 0.0848
Answer:

Step-by-step explanation:
5 can go into 19 three times. This will leave a remainder of 4. Therefore, 19/5 as a mixed number is 3 4/5.
