8. example 1 - calculating hourly wages
joe works at the local hardware store. he is earning $7.75 per hour. if this
upcoming week he works a total of 36 hours, what will his gross earnings be for
the week?

279.00

Step-by-step explanation:

7.75x36

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

an advantage of the standard deviation is that it increases as the dispersion of the data increases. e. the interquartile range is preferred when the data are not skewed or no have outliers. an advantage of the standard deviation is that it uses all the observations in its computation.
