Answer:
first do:
60mph * 4 hours= 240mi
Let D = the distance the passenger train has to
travel to catch the freight train
Start a stopwatch when the passenger train leaves
Let t = the time on the stopwatch when they meet
Equation for freight train:
d-240=60t
Equation for passenger train:
d=100t
all together:
100t-240=60t
we can do 100t-60t because they both have (t)= 40t
40t=240 *now divide 240 by 40= 6
THEN do:
D= 100mph x 6= 600mi
They will meet 600 mi from the station
to check:
d-240=60t x 6
600-240= 360
60 x 6= 360
360=360
Answer:
x=3
Step-by-step explanation:

Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $188.876
Standard Deviation, σ = $4.6412
We are given that the distribution of stock price is a bell shaped distribution that is a normal distribution.
Formula:
P(stock price is between $186.26 and $192.47)
0.494 is the probability that on a selected day the stock price is between $186.26 and $192.47.
