Answer:
x=6
Step-by-step explanation:
You can use trig for this
Cos (45)=
x=
x=6
81p²+90p+25=(9p)²+2*9p*5+5²=(9p+5)²
so the side length of the paining is 9p+5

Assuming constant probability of p=0.55, we can use the binomial distribution, with n=5, x=4 and p=0.55,
P(X=x)=C(n,x)*p^4*(1-p)^(n-x)
=>
P(X=4)=C(5,4) (0.55)^4 (0.45)^1
=5!/(4!1!)(0.55^4) (0.45^1)
=0.2059 (approx.)
