Answer: 3.886 m/s
Step-by-step explanation:
1 A.
The initial velocity (u) = 10 km/hr or 2.77 m/s
1 B.
The final velocity (v) = 60 km/hr or 16.66 m/s
1 C.
5 seconds.
1D. Acceleration = Final velocity - initial velocity / time
= 16.66 m/s - 2.77 m/s / 5 s
= 3.886 m/s.
Answer:
a) 50%
b) 68%
c) 99%
Step-by-step explanation:
for a standard normal curve ,
a) since the standard normal curve is symmetric and centred around μ , 50% of the curve lies at the left of μ and 50% lies to the right
b) according to the 68-95-99 rule, 68% of the standard normal curve lies from μ − σ and μ + σ
c) from the same rule , 99% of the standard normal curve lies from μ − 3σ and μ + 3σ
