Answer:
0.1749
Step-by-step explanation:
We are to find the probability that none of the house-holds tuned to 50 minutes.
P(tune to 50 minutes) = 0.16
p = 0.16
q = 1 - 0.16
q = 0.84
number of households (n) = 10
x = number of households that tuned at 50 minutes
since none of the household tuned, then:
x = 0
Using the binomial expression:
P(x =0) = 0.1749
Distance = rate*time
Let distance from X to Y be 'd'
From the equation we can solve for 'time'
time = distance/rate
The total time it takes to go 50 mph ,then 40 mph is:
The total time it takes to go 45 mph round trip is:
We know that the round-trip at 45 mph takes half-hour shorter, so by adding '1/2' to its time it will be equal to the time to go 50 then 40.
Answer: The distance from X to Y is 900 miles.
Answer:
1,400
you would add another 0 to it since it is %10
