____ [38]

Answer:

The correct answer: 0.05404

Step-by-step explanation:

Given:

Binomial distribution = x

n = 10

and p = 0.09

solution:

P(X=x) =1 0Cx*(0.09^x)*((1-0.09)^(10-x)) for x=0,1,2,...,10

So the probability is calculated by the Formula:

P(X>=3) = 1-P(X=0)-P(X=1)-P(X=2)

putting the given values in the formula

= 1-10C0*(0.09^0)*((1-0.09)^(10-0))-...-10C2*(0.09^2)*((1-0.09)^(10-2))

= 0.0540400

Thus, the correct answer: 0.05404

Answer:

The length of rope is 420 feet.

Step-by-step explanation:

Kingston flew 300 feet above the water.

Perpendicular = 300 feet

The boat driver informed him the angle of elevation from the boat to that height is typically 45.5 degrees

We are supposed tho find the length of the rope i.e. Hypotenuse

$Sin \theta =\frac{Perpendicular}{Hypotenuse}\\Sin 45.5^{\circ} = \frac{300}{Hypotenuse}\\Hypotenuse = \frac{300}{Sin 45.5^{\circ}}\\Hypotenuse = \frac{300}{0.7132}\\Hypotenuse = 420.63$

So,The length of rope is 420 feet.
