When studying radioactive material, a nuclear engineer found that over 365 days, \( 1,000,000 \) radioactive atoms decayed to 973,521 radioactive atoms, so 26,479 atoms decayed during 365 days a. Find the mean number of radioactive atoms that decayed in a day b. Find the probability that on a given day, 51 radioactive atoms decayed. a. The mean number of radioactive atoms that decay per day is 72.545 (Round to three decimal places as needed.) b. The probability that on a given day, 51 radioactive atoms decayed, is (Round to six decimal places as needed)

De ser posible, Calcule la combinacion linal a Se indica en coda caso \( 2 C-3 E \) \( C=\left[\begin{array}{ccc}3 & -1 & 3 \\ 4 & 1 & 5 \\ 2 & 1 & 9\end{array}\right]\left[\begin{array}{ccc}3 & -1 & 3 \\ 4 & 1 & 5 \\ 2 & 1 & 3\end{array}\right]-E \)

Solve for \( v \) \( -3(v+6)=9 \) \( v=\square \)

3. Para el siguiente patalelepipedo con coordenadas \( A(+2,+2), B\left(+6{ }^{2}\right. \) \( c(+6,+5), D(+2,+5), \epsilon(+8,+7), F(+4,+7), G(+4,+4) \) y \( H(+8,+4) \), grapicar en plano cartesíano. calcular distancias de lados, perimetro, area y volumen.

D) \( \left(\frac{2}{3}-\frac{41}{6}\right) \cdot\left(-\frac{9}{14}\right)= \)
