Need more information to answer this question. How many socks total? How many colours? How many socks of each colour?

You need to know how many socks there are in total. if they are all back socks, then there is a definite probability that stefan with take out two socks of the same colour. but if there is one sock of each colour, there is a lower probability that he will take out the same colour sock.

Differential Equations Problem
fgiga [73]

Answer:

y=\frac{t^2e^{2t}}{3}+ce^{2t}

Step-by-step explanation:

We have given differential equation \frac{dy}{dt}-2y=t^2e^{2t}

We know that linear differential equation is given by \frac{dy}{dt}+Py=Q

On comparing with standard equation P = -2 and Q= t^2e^{2t}

Now integrating factor IF=e^{-Pdt}

IF=e^{-2dt}=e^{-2t}

Now solution of differential equation is given by

y\times IF=\int\ IF\times Q\ dt

y\times e^{-2t}=\int\ e^{-2t}\times t^2e^{2t}\ dt

y\times e^{-2t}=\frac{t^2}{3}+c

y=\frac{t^2e^{2t}}{3}+ce^{2t}

Write the equation of the line that passes through (−3, 5) and (2, 10) in slope-intercept form
BigorU [14]
Slope = (10 -5)/(2+3) = 5/5=1

y = mx + b
5 = 1(-3) + b
b =8

so equation y = x +8

answer: <span>y = x + 8(first choice)</span>
