The cattle train
speed - 36.5 km/h
time - x h

the passenger train
speed - 29.2 km/h
time - (2.4+x) h

The cattle train caught up to the passenger train so the distance they travelled is the same.
Distance is speed times time.

36.5 \times x=29.2 \times (2.4+x) \\
36.5x=70.08+29.2x \\
36.5x-29.2x=70.08 \\
7.3x=70.08 \\
x=\frac{70.08}{7.3} \\
x=9.6 \\ \\ 2.4+x=2.4+9.6=12

The passenger train travelled for 12 hours before the cattle train caught up.

djyliett [7]

Answer:

X₀ = 71.65

Step-by-step explanation:

given,

mean (μ ) = 64

standard deviation (σ) = 9

                                 σ²  = 81

selected candidate are top 20 % candidate

P( X > X₀)  = 0.2

P( Z > \dfrac{X_0-\mu}{\sigma}) = 0.2

P( Z > \dfrac{X_0-64}{9})= 0.2

P( Z > Z₀)  = 0.2

Z_0 = 0.85 = \dfrac{X_0-64}{9}

X₀ = 71.65

Hence, the cut off score is equal to X₀ = 71.65
