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:
x=2
Step-by-step explanation:
1 is = 100%, or 10/10, 1/1, and 1.00
if we have a double of 1, we would double, now 1 and 1=200% 20/10, 2/1, 2.00
turning these franction into whole numbers we will now have
so now we have our answer, which is 2
now lets learn 1+1 as pi-
