Experience shows that a ski lodge will be full (153 guests) if there is a heavy snow fall while only partially full (62 guests)

with a light snow fall. What is the expected number of guests if the probability for a heavy snow fall is .40

<h2>Answer:</h2><h2>The expected number of guests if the probability for a heavy snow fall is .40 = 98.4 </h2>

Step-by-step explanation:

The total number of guests for lodge to be full = 153

During heavy snow fall, the lodge will be full.

The expected number of guests during heavy snow fall = 153

During partial snow fall, the expected number of guests = 62

The probability of heavy snowfall = 0.4

The probability of partial snow fall = 1 - 0.4 = 0.6

The expected number of guests = [(0.4) (153)] + [(0.6) (62)]

= 61.2 + 37.2

 =  98.4

Its 10 times farther because each time you add another exponent, you're multiplying by 10, and so the difference is 1 in this case. Therefore it is C--10

Find a particular solution to the differential equation y′′+2y′+y=2t2−t+3e−2t. y′′+2y′+y=2t2−t+3e−2t.
Jlenok [28]
y''+2y'+y=2t^2-t+3e^{-2t}

The characteristic equation is

r^2+2r+1=(r+1)^2=0\implies r=-1

so the characteristic solution is

y_c=C_1e^{-t}+C_2te^{-t}

For the particular solution, we can try looking for a solution of the form

y_p=at^2+bt+c+de^{-2t}
\implies{y_p}'=2at+b-2de^{-2t}
\implies{y_p}''=2a+4de^{-2t}

Substituting into the ODE, we have

(2a+4de^{-2t})+2(2at+b-2de^{-2t})+(at^2+bt+c+de^{-2t})=2t^2-t+3e^{-2t}
at^2+(4a+b)t+(2a+2b+c)+de^{-2t}=2t^2-t+3e^{-2t}
\implies\begin{cases}a=2\\4a+b=-1\\2a+2b+c=0\\d=3\end{cases}\implies a=2,b=-9,c=14,d=3

So the general solution to the ODE is

y=y_c+y_p
y=C_1e^{-t}+C_2te^{-t}+2t^2-9t+14+3e^{-2t}

An object is launched from the roof of a building 192
myrzilka [38]

Answer:

252 ft

Step-by-step explanation:

h(t) = -16t^2 +64t + 192

We want to find h when t= 2.5

h(2.5) = -16 (2.5)^2 +64(2.5) +192

          =-16(6.25) +160+192

            =-100+160+192

               =252
