Lashonda started to run on a treadmil, after setting it's timer for 64 minutes, The display states that she has finnished 68% of her run, how many minutes have gone by?

Step-by-step explanation:

It is 64*0.32=20.48 minutes or 20.5 minutes.

43.52

Step-by-step explanation:

first you have to multiply the amount of time in all by the percent she has done. then after that you divide by 100.

a. the residual plot for model 1 has a random pattern and is a good fit for the data.

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."
