(f-g)(x) = 4x²-2x-12 which,evaluated at x=4, gives 64-8-12=44
The length of the ladder is 25 feet.
<u>Explanation:</u>
Height of the House, h = 24 feet
Distance between the house and the ladder, b = 7 feet
length of the ladder, x = ?
The house makes 90° with the base of the ladder.
Using pythagoras theorm,
x² = h² + b²
x² = (24)² + (7)²
x = √625
x = 25
Therefore, the length of the ladder is 25 feet.

b)0.5768
Step-by-step explanation:
Given:
µ=3
Poison probability is given by :

a) Evaluating at k=3

b)Evaluating at k=0,1,2:



Use complement rule:
P(x≥3)= 1 - f(0) - f(1) - f(2)= 1- 0.0498 - 0.1494 - 0.2240 =0.5768
