Answer:
80 and 90
Step-by-step explanation:
this is a binomial problem: p = 0.7 and q = 0.3
a) (0.7)^6
b) (6C4)(0.7)^4(0.3)^2
c) Pr ( at least 4) = Pr(4) + Pr(5) + Pr(6) = (6C5)(0.7)^5(0.3) + (0.7)^6
d) Pr (no more than 4) = 1 - Pr(at least 4) = 1 - (answer from c)

Answer:
The rose garden is 125.82 feet apart from the lily garden.
Step-by-step explanation:
See the attached diagram.
The position of Florence is A and the position of the rose garden and the lily garden forms a triangle Δ ARL.
Now, from the property of triangle, we can write
x² = 80² + 140² - 2 × 140 × 80 × Cos 63°
⇒ x² = 15830.61
⇒ x = 125.82 feet.
Therefore, the rose garden is 125.82 feet apart from the lily garden. (Answer)
