Answer:
I think it would be 540
Step-by-step explanation:
3.5% multiplied by the 400 equals 140. 140+400 equals 540
The percentage error can be calculated using the following rule:
% error = difference between values / accepted value
From the givens:
The accepted value = 40%
Difference between values = 40% - 37% = 3%
Substitute in the equation to get the percentage error as follows:
% error = (3/40) * 100 = 7.5%
Answer:
1/10
Step-by-step explanation:
1 + 1/2 = 1 1/2
1 - 1/8 = 7/8
1 + 1/5 = 1 1/5
1 - 1/3 = 2/3
1 + 1/10 = 1 1/10
One and one tenth is closest to one because one tenth is the smallest amount that would need to be added or taken away to get exactly one. Hope I helped!
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.
