Equating 'x' to zero
Answer:
A) 0.005
B) 0.001
C)0.0495
Step-by-step explanation:
Let A be the event that an aircraft is present and let B be the event the radar registers its presence.. Thus;
P(A) = Probability that an aircraft is present
P(A') = Probability that an aircraft is not present
P(B) = Probability that the radar generates an alarm
P(B') = Probability that the radar doesn't generate an alarm
Thus from what we are given, we have;
P(A) = 0.05
P(A') = 0.95
P(B) = 0.99
P(B') = 0.01
P(B|A') = 0.1
A) Probability of a false alarm will be;
P(A' ∩ B) = P(A) × P(B|A')
P(A' ∩ B) = 0.05 × 0.1 = 0.005
B) probability of missed detection is;
0.1 × (1 - 0.99) = 0.001
C) probability that an aircraft is present given that the radar registers a presence will be;
P(A ∩ B) = P(A) × P(B)
P(A ∩ B) = 0.05 × 0.99
P(A ∩ B) = 0.0495
Respuesta: x/2,5=y/5=4/5=0,8
x/2,5=y/5
Multiplicando ambos lados de la ecuación por 5:
5(x/2,5)=5(y/5)→2x=y→y=2x
Sustituyendo y por 2x en la ecuación x+y=6:
x+2x=6
Resolviendo para x: Sumando términos semejantes:
3x=6
Dividiendo ambos lados de la ecuación entre 3:
3x/3=6/3
x=2
Sustituyendo x por 2 en la formula y=2x
y=2(2)→y=4
Determinando la proporción:
x/2,5. Sustituyendo x por 2:
2/2,5
Multiplicando numerador y denominador por 2:
2*2/(2,5*2)=4/5
La proporción es 4/5=0,8
Si lo hacemos con y:
y/5
Reemplazando y por 4:
4/5=0,8 (la misma proporción)
Find the unit rate for each Olivia and Ryan:
2 2/5 km 15 36 km
------------ * ------- = ------------ = 3.6 km/hr (Olivia)
2/3 hr 15 10 hr
4 1/2 km 2 9 km
------------- * --------- = --------- = 3 km/hr (Ryan)
1 1/2 hr 2 3 hr
Olivia walked 0.6 km/hr faster than did Ryan.
