Answer:
a) 279 b)254
Step-by-step explanation:
Mean = 269 days
standard deviation = 8 days
let n be the pregnancy lenght.
using normal distribution formula
z = (n – mean)/ standard deviation
n = z * standard deviation + mean
Now, z values for the top 12% has to be found using a z table.
The top 12% means 88% of area under the curve. In this case z = 1,176
n = 1,176 * 8 + 269
n = 278.4 = 279
The bottom 3% means 97% of area under the curve. In this case z = -1,882
n = -1,882 * 8 + 269
n = 253.94 = 254
Answer:
8 3/4
Step-by-step explanation:
find the greatest common factor of 35 and 4, which is 1. Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4
(If its not right let me know so I can rethink my answer)
Answer:
y = 1500 - 200x
Step-by-step explanation:
y would be the amount of water remaining in the pool
x would be the amount of hours that have passed.
So the only change I made was to convert 400 every 2 hrs to 200 every hour.
makes sense?
670,130,000 Km or 416,399,477 Miles apart
