the graph below expresses a radical function that can be written in the form f(x)=a(x+k)^1/n+c what does the graph tell you about the value of k in this function

Segment ab is shown on the graph. which shows how to find the x-coordinate of the point that will divide ab into a 2: 3 ratio using the formula

The brain volumes (cm cubed) of 50 brains vary from a low of 904 cm cubed to a high of 1488 cm cubed. use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of 175.5 cm cubed, assuming the estimate is accurate if it is within 15 cm cubed

Combine the information in the problem and the chart using the average balance method to solve the problem.
