Answer:
C. 0.12
Step-by-step explanation:
<u>Independent events</u>
The outcome of one event does not affect the outcome of the other. If A and B are independent events then the probability of both ocurring is:
P(A and B) = P(A) x P(B)
With P(A) = 0.40 and P(B) = 0.30 then
P(A and B) = 0.40 x 0.30 = 0.12

Step-by-step explanation:
Answer:
1 m/s
Step-by-step explanation:
the area of the triangle = A = ¹/₂ab
where a is the distance covered by the first person and b is the distance covered by the second person. since they walk at the same speed, then a = b, so our formula can be changed to A = ¹/₂x²
now we find the derivative of both sides:
dA/dt = ¹/₂ ⋅ dx²/dt
dA/dt = ¹/₂ ⋅ 2x ⋅ dx/dt
dA/dt = x ⋅ dx/dt = x ⋅ velocity
we are told that x = 5 m, and dA/dt = 5 m²/s
velocity = dA/dt / x
velocity = 5 m²/s / 5 m = 1 m/s
