1 answer:
Dafna11 [192]3 years ago
7 0

Answer:

Options (2) and (5)

Step-by-step explanation:

Given ratio is a : b and b : c

\frac{a}{b}=\frac{b}{c}

\frac{b}{a}= \frac{c}{b} [Option 2]

\frac{a}{b}=\frac{b}{c}

b × b = a × c

b² = ac

If a = b,

b² = bc

b = c [Option 5]

Therefore, Options (2) and (5) are the correct options.

Answer: \dfrac{15}{64}

Step-by-step explanation:

Given

Inside radius of figure r_1=\frac{14}{2}=7\ ft

Outside radius of figure r_2=\frac{16}{2}=8\ ft

Area of outside region is A_1=\pi (8^2)

Area of inside region A_2=\pi (7)^2

Area of shaded region A_1-A_2

Probability that point lies inside the shaded region is

\Rightarrow P=\dfrac{A_1-A_2}{A_1}\\\\\Rightarrow P=\dfrac{\pi (8^2-7^2)}{\pi 8^2}\\\\\Rightarrow P=\dfrac{64-49}{64}\\\\\Rightarrow P=\dfrac{15}{64}
