<u>Answer:</u>
The height of the ladder is 14.491 feet
<u>Explanation</u>:
Given the height is 11 feet
Base = 7 + 2 = 9 feet
Consider the ladder to be the hypotenuse
Applying Pythagoras Theorem,
![H^2 = P^2 + B^2](https://tex.z-dn.net/?f=H%5E2%20%20%20%3D%20P%5E2%20%2B%20B%5E2)
Substituting the values in the above formula,
= 112 + 92
= 121 + 81
= 210
H = sqrt(210)
H = 14.491
Therefore, the height of the ladder is 14.491 feet

Answer:
0.6708 or 67.08%
Step-by-step explanation:
Helen can only make both free throws if she makes the first. The probability that she makes the first free throw is P(C) = 0.78, now given that she has already made the first one, the probability that she makes the second is P(D|C) = 0.86. Therefore, the probability of Helen making both free throws is:
![P(C+D) = P(C) *P(D|C) = 0.78*0.86\\P(C+D) = 0.6708](https://tex.z-dn.net/?f=P%28C%2BD%29%20%3D%20%20P%28C%29%20%2AP%28D%7CC%29%20%3D%200.78%2A0.86%5C%5CP%28C%2BD%29%20%3D%200.6708)
There is a 0.6708 probability that Helen makes both free throws.
Answer:
Step-by-step explanation:
if you multiply any number in the first sequence by 3, you get that number in sequence 2 in the same position as the first number.
6x3=18
7x3=21
8x3=24
9x3=27
