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:
the value of the digit 8 in 80,000 is 10 times the value of the digit 8 in 8,000
Step-by-step explanation:
i’m pretty sure this is how it’s supposed to be written, if not i’m sorry
can you provide a picture please
Slope intercept form would be Y= 8/3x - 8

Answer:
see attached
(x, y) = (8, 4)
Step-by-step explanation:
The relations given in the problem statement let you write two equations. One for the number of shots, and one for the number of points. The variables x and y are defined in the problem statement.
x + y = 12 . . . . . total number of shots
x + 2y = 16 . . . . total number of points
__
These equations are easily plotted by considering their x- and y-intercepts. The x-intercepts of the equations are found when y=0, so are 12 and 16, respectively.
The y-intercepts are found when x=0, so are 12 and 8, respectively. The two lines are shown in the attached. The first is blue; the second is red. Their point of intersection at (x, y) = (8, 4) is circled.
- the number of free throws Angel made was 8
- the number of 2-point shots Angel made was 4
