If G is a random variable representing the gestation period, an it is assumed to have a normal distribution with the given mean and standard deviation, then Prob(250 < G < 282) = Prob(-1 < Z < 1) where Z has the standard normal distribution. = 0.6827 = 68.3%
70/100 X 250 = 175 So, 175 is 70% of 250
Adding 150 250 times is the same as 150 x 250: 150 x 250 = 37,500
250% of 60= 250% * 60= 2.5 * 60= 150
150/250 = 60%
As 150 is the lowest and 900 is the highest, the range is 750.
The number directly in the middle of 175 and 250 is (175 + 250)/2 = 212.5
If G is a random variable representing the gestation period, an it is assumed to have a normal distribution with the given mean and standard deviation, then Prob(250 < G < 282) = Prob(-1 < Z < 1) where Z has the standard normal distribution. = 0.6827 = 68.3%
some multiples are 25, 50, 75,100, 125, 150, 175, 200, 225, 250
75
25, 50, 75, 100, 125, 150, 175, 200, 225, 250.
25, 50, 75, 100, 125, 150, 175, 200, 225, 250
They are 25*1, 25*2, 25*3, 25*4 and 25*5. You seem to be unaware of the fact that you could have obtained the answer much more easily and quickly by using the calculator that comes as part of your computer.
25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, . . .
25, 50, 75, 100, 125, 150, 175, 200, 225, 250, 275, 300, 325, . . .
175 over 250 will simplify to 7 over10.
70/100 X 250 = 175 So, 175 is 70% of 250
