Given that y varies directly as x and inversely as 2m_1 and that y=5 when x=7 and m=4calculate the constant variation of k. the value of y when x =2 and m=3.the value of m when y=2 and x =4

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50

answer: .64

step-by-step explanation

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

faster, im not sure why but i know it is faster
