Answer:
The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.
The percentage change (an increase) wa 40%.
Ok, so for 9/2,just divide,which will get you 4 1/2 since 2 can only go into 9 4 times.then for 10/7, do the same thing,and you will get 1 3/7 since 7 can only go into 10 once
You have to convert cm to m or m to cm (all if them need to have the same unit)
50cm= 0.5m
20cm= 0.2m
l=3+0.5= 3.5m
b=2+0.2= 2.2m
A=(3.5)(2.2)= 7.7m^2
8 plus 8 is 16. 5 plus 5 is 10. 10 plus 16 is 26. 26cm.
Answer:
Step-by-step explanation:
The z-score corresponding to a given area of a distribution, is the number of standard deviations that the values in that area have/are from the mean.
In this case, we have a STANDARD normal distribution. In a standard normal distribution, the mean is 0 and the standard deviation is 1.
The Z-score corresponding to a given area, say the 30th percentile is
X = 0 + (-0.524)(1)
Hence, the X (number of values in the given percentile - in this case, 30th) is same as the z-table or z-calculator value for the 30th percentile in ANY normal distribution.
