3. The number of gallons of water in a tank, y, over a period of x hours is shown in the graph below. 90 80 40 60 50 40 30 20 10 1 2 3 4 5 6 What is the constant of proportionality in this situation? what is the answr DC

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

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.
