When the variance of a sample of 144 observation is 576 then, the standard deviation of the sample equals 24
The variance is a measure of variability. It is calculated by taking the average of squared deviations from the mean. Variance tells you the degree of spread in your data set
Standard deviation is a statistic that measures the dispersion of a dataset relative to its mean and is calculated as the square root of the variance.
Given,
The number of samples = 144
The variance = 576
The standard deviation is the square root of variance
The standard deviation = =24
Hence, when the variance of a sample of 144 observation is 576 then, the standard deviation of the sample equals 24

Answer:
No
Step-by-step explanation:
We can tell if these ratios are equivalent by dividing the numerators and denominators. <em>If we end up with the same result, these ratios are equivalent</em><em>.</em>

These two numbers are not equivalent, so these ratios aren't equivalent to each other

Answer:
squr. 39
Step-by-step explanation:
See attached graph.
Form a right triangles and determine the length of the two sides (BC and AC). Then calculate the hypotenuse (AB) with the Pythagorean Theorem.
AB = 13
I'm not sure what "squr.3AB really means. 3AB is 39. The square root of 39 is 6.4, if square root is what is meant.
