No she is not because:

Friend 1(page)x20(pages)=20(pages)
Aileen 1.5(pages)x20(pages)=30

Answer:

M_x = 2, M_y = 3

Center of mass at (\frac{3}{10},\frac{2}{10})

Step-by-step explanation:

Given a set of objects m_1, \dots, m_k located at the points P_1(x_1, y_1), \dots, P_k(x_k,y_k) The moments Mx and My are calculated as follows.

M_x = \sum_{n=1}^k m_n\cdot y_n, M_y = \sum_{n=1}^k m_n\cdot x_n

and the Center of mass is given at the coordinates (\frac{My}{M}, \frac{Mx}{M}) where M is the total mass of the system.

We have that m1=3, m2=4 and m3=3, so M = 3+4+3 = 10.

We have that m1 is at point P1(2,-6), m2 at point P2(-3,2) and m3 at point P3 (3,4), then

M_x = \sum_{n=1}^k m_n\cdot y_n = 3\cdot(-6)+4\cdot(2)+3\cdot(4)=2

M_y = \sum_{n=1}^k m_n\cdot x_n = 3\cdot(2)+4\cdot(-3)+3\cdot(3)= 3

Then, the center of Mass is at (\frac{3}{10},\frac{2}{10})

aniked [119]

Answer:

25.6%

Step-by-step explanation:

Purchase price = $250 / share

Jan - feb : 38% decrease

(100 - 38)% * 250 = $155

February - March : 20% increase

(100 + 20)% * $155

120% * $155 = $186

Percentage decrease from January to March :

[(250 - 186) / 250] * 100%

(64 / 250) * 100%

0.256 * 100%

25.6%
