NemiM [27]

Answer: The length of the second arc is 12 feet.

Step-by-step explanation:

Since we know that

A rope is swinging in such a way that the length of the arc is decreasing geometrically,

Length of first arc = 18 feet

Length of third arc = 8 feet

Let the length of second arc be x

As we know that

\frac{a_2}{a_1}=\frac{a_3}{a_2}\\\\\frac{x}{18}=\frac{8}{x}\\\\x^2=18\times 8\\\\x^2=144\\\\x=\sqrt{144}\\\\x=12

Hence, the length of the second arc is 12 feet.

Step 2: define the distribution of this variable

x ~ binomial distribution ( p=0.02, n=25)

this is because x is the number of succes in 25 trials.

Step 3: using the binomial distribution formula

P(x=1)= (25C1)*(0.05^1)*(1-0.05)^(25-1)=0.3079

where (25C1) is a combination
