Answer:
1/6 or 0.16666... can be written rounding off to three decimal digits such as:
(rounding off to three decimal digits)
Step-by-step explanation:
As we know that
In order to round off three decimal places (or digits ), we need to check:
- the digit in the fourth place.
- If the digit in the fourth place is greater than 5, then we must add 1 to the previous digit.
Therefore, 1/6 or 0.16666... can be written rounding off to three decimal digits such as:
- (rounding off to three decimal digits)
Answer:
Standard deviation is 25.4
Step-by-step explanation:
The standard deviation is a metric that determines the variance a set of data has both above and below the mean. A standard deviation of 25.4 means that the values in a given data set are dispersed in a range of 25.4 units both above and below the mean.
The standard error refers to the Standard Error of the Mean (SEM) which measures the precision of the mean in terms of how much a sample mean is likely to differ from the population mean. By using SEM, individuals can estimate how sure they can be that the mean of the sample reflect the true mean of the population. The standard error always is lower than the standard deviation. Since, 25.4 is the higher number, this number would be the standard deviation.
Look at the gradient of both the equations (the x multiplier, usually known as m), and there are a couple of rules:
Parallel: The gradients are identical
Perpendicular: Look at the gradients as fractions. To get the perpendicular to a gradient you flip the fraction and change the sign. If this is the case for the two gradients, then they are perpendicular.
