Answer:
2.5
Step-by-step explanation:
5/8 ÷ 1/4
Division sign changes to multiplication and the reciprocal of the divisior is used to multiply instead :
5/8 * 4/1
= (5*4) / (8*1)
= 20 / 8
= 2.5

Answer:
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Step-by-step explanation:
In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:
In which
x is the number of sucesses
e = 2.71828 is the Euler number
is the mean in the given time interval.
What is the probability that exactly two such busses arrive within 3 minutes of each other
The mean is one bus each 10 minutes. So for 3 minutes, the mean is 3/10 = 0.3 buses. So we use 
This probability is P(X = 2).
There is a 3.33% probability that exactly two such busses arrive within 3 minutes of each other.
Answer:
Step-by-step explanation:
5*50 + 10y = 800
250+10y=800
10y=550
y=55
The soccer team collected $800 at a car wash fundraiser. They charged $5.00 for small vehicles and $10.00 for larger vehicles. The amount collected can be modeled by the equation 5x + 10y = 800, where x represents the number of small vehicles and y represents the number of larger vehicles. If the number of larger vehicles washed was 50, how many small vehicles were washed in total? 60. The soccer team collected $800 at a car wash fundraiser.

~~~~~~~~~~~~~~~~~~~~~~
5x + 10y = 800 and y = 50 ====>
5x + 10*50 = 800 ====> 5x + 500 = 800 ====> 5x = 800-500 = 300 ====> x = 300%2F5 = 60
