Answer:
0.36
Step-by-step explanation:
To find the probability, just multiply.
probability of red candy * probability of pink cookie
0.9*0.4=0.36
I hope this helps!
100*2.2=220
80*2=176
220+176=396
So the two trains will take 2.2 hours so that they are 396 miles apart.
<em>Thank you very much for the points friend! It's helping</em> a lot!
First: the homogeneous solutions: the characteristic equation is4r^2 - 4r - 3 = 0which has roots r = 3/2, -1/2 hence the homogeneous solution isy = c1.exp(-x/2) + c2.exp(3x/2)
next you need the general form for the guess for yp and that isyp = A1cos(2x) + A2sin(2x)
Now substitute that into the equation and solve for A1, A2.
