Answer:
Step-by-step explanation:
1km = 1000m
5a. 5.768km = 5768m = 57.7m
5b. 9.039km = 9039m = 90.4m
5c. 8.48km = 8480m = 84.8m
5d. 17.685km = 17685m = 17.7m
5e. 17.658km = 17658m = 17.7m
To round to the nearest 100m just divide by 100 and then round it off. like 57.68=57.7m because 8 is more than 5 so 6 becomes 7 to one decimal.
Rule is applied for all the other questions too.
A ratio that compares two quantities measured in different units is a conversion factor!

Answer:
The z-score for the 34-week gestation period baby is 0.61
Step-by-step explanation:
The formula for calculating a z-score is is z = (x-μ)/σ,
where x is the raw score,
μ is the population mean
σ is the population standard deviation.
We are told in the question that:
Babies born after a gestation period of 32-35 weeks have a mean weight of 2600 grams and a standard deviation of 660 grams. Also, we are supposing a 34-week gestation period baby weighs 3000grams
The z-score for the 34-week gestation period baby is calculated as:
z = (x-μ)/σ
x = 3000, μ = 2600 σ = 660
z = 3000 - 2600/660
= 400/660
=0.6060606061
Approximately, ≈ 0.61
