Answer:
Option 2 is true.
Step-by-step explanation:
Th sum of probabilities of two complementary events is one, which implies
P(A) + P(B) = 1
So,
P(B) = 1 - P(A)
Answer:
The radius of the water bottle is 2.72cm
Step-by-step explanation:
In this question, we are concerned with calculating what the radius of the cylindrical water bottle is given its volume and height.
Mathematically, the volume of a cylinder is V = pi * r^2 * h
From the question, we know that V = 179 cm^3. , h = 7.7cm while r = ?
we substitute these values into the volume equation.
179 = pi * r^2 * 7.7
179 = 3.14 * r^2 * 7.7
179 = 24.178 * r^2
r^2 = 179/24.178
r^2 = 7.403
r = square root 7.403
r = 2.72 cm

Answer:
Step-by-step explanation:
You know an angle, the side opposite the angle, and the side between them.
Use the Law of Sines.
j3 = arcsin(2.7sin(j1)/4.2) ≅ 27.0°
j2 = 180°-j1-j3 ≅ 108.0°
x = distance from j1 to j2
= 4.2sin(j2)/sin(j1)
≅ 5.7 miles
