Answer:Yes
Step-by-step explanation:
5×3=15. 9×3=27
I'm pretty sure it's B you have it correct
199.
the z score for the 90th percentile is 1.28, so you can solve the equation

which gets you the 199
Answer:
xA = 10 km
xB = 7.071km
Step-by-step explanation:
A/Q
p=5km
For point A
∅ = 30°
sin ∅ = p/h
sin 30° = 5/h
1/2 = 5/h
h = 5×2
h=10km
For point B
sin ∅ = p/h
sin 45° = 5/x
1/√2 = 5/x
x = 5 × √2
x = 7.071 km
.: Points A and B are 10 km and 7.071 km away from the airplane.
Answer:
-4/3
Step-by-step explanation:
Moving from C(-4, 4) and D(5, -8) we see that x (the 'run') increases by 9 and that y (the 'rise') decreases by 12. Thus, the slope m is rise/run, or
m = -12/9 = -4/3
