Angie plays the violin. the number of hours she praticed each week for 5 week are 2,3,5,7, and 8. the mean number of hours per week she praticed is 5. what is the mean absolute deviation of data?

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

12cm

the answer is d

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195
