Agiven data set has a symmetrical shape.
which statement is true about the data set?
it cannot be determined if the mean is greater than, less than, or equal to the median.
the mean is less than the median.
the mean is greater than the median.
the mean is equal to the median.

The mean is equal to the median.

Step-by-step explanation:

Median is the middle value of a given data set. In a symmetric distribution, the data on the left side of the median is equal to the data on the right side of the median. Therefore, the mean of that data is equal to the median of the symmetric distribution.

step-by-step explanation:

since the triangle is right use pythagoras' identity to solve for a

the square on the hypotenuse is equal to the sum of the squares on the other two sides, that is

a² + 8² = ( )²

a² + 64 = 73 ( subtract 64 from both sides )

a² = 9 ( take the square root of both sides )

a = = 3
