Answer: It's 7
Step-by-step explanation:
Answer:
Prob ( 41 <= X <= 77) =
Prob ( (41-59)/9 <= Z <= (77-59)/9 ) = <--- changes to z scores
Prob ( -18/9 <= Z <= 18/9 ) =
Prob ( -2 <= Z <= 2) =
Prob ( z<=2) - Prob(Z<=-2) = <--- by property of the normal bell curve
= 0.9772 - 0.0228 <--- per the normal distribution table
= 0.9544
Step-by-step explanation:
make sense ?
The change in velocity = -10 - -2 = 8 m/s
The time was 4 seconds.
Acceleration = 8 m/s / 4 s = 2 m/s^2
