R(x)=2square root of x S(x)= square root of x (rs)(4)=

Step-by-step explanation:

Given

Required

Determine

In functions:

This implies that:

Substitute values for r(x) and s(x)

Substitute 4 for x

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .

answer: .64

step-by-step explanation

set up the formula for standard deviation for this set of numbers, then simplify
