Answer:
the middle 50% of most lengths of pregnancies ranges between 255.62 days and 274.38 days
Step-by-step explanation:
Given that :
Mean = 265
standard deviation = 14
The formula for calculating the z score is 
x = μ + σz
At middle of 50% i.e 0.50
The critical value for 
From standard normal table
+ 0.67 or -0.67
So; when z = -0.67
x = μ + σz
x = 265 + 14(-0.67)
x = 265 -9.38
x = 255.62
when z = +0.67
x = μ + σz
x = 265 + 14 (0.67)
x = 265 + 9.38
x = 274.38
the middle 50% of most lengths of pregnancies ranges between 255.62 days and 274.38 days
Answer:
1.1(for infinity) or 0.9
Step-by-step explanation:
it depends if you do 90/100 or 100/90
90/100 = 0.9
100/90 = 1.1(for infinity)
so sorry i couldn't figure out specifically what to divide but i hope both of these answers helped you!
Take the like terms on one side:
2m=6-14
2m = 8
m= 8/2
m= 4
8.129
8.219
8.3
8.37
Always go from left to right as compare the values in the tenth, then hundredths, then thousandths place. Remember that if there is no digit, it is a 0 (after the decimal of course).
The definition of the set E gives you a natural choice for the limits in the integral:
Computing the integral, we get
