W + y + v + 88 = 180
22 + y + 43 + 88 = 180
y = 27
Answer:
The probability that no boats arrive is 
.
Step-by-step explanation:
Poisson distribution:
Poisson distribution is a statistical distribution that helps to find out the probability of a certain is likely occur a specified period of time.
= rate.
Given that, Poisson distribution at a rate of 3 per hour.
= 3
t=2
x=0
The probability that no boats arrive is
Answer:
0 ≤ x ≤ 18
Step-by-step explanation:
Let 'x' be the number of youth tickets purchased at the zoo and 'y' be the number of adult tickets purchased at the zoo.
At a zoo, youth tickets cost $5 and adult tickets cost $9. A group spent a total of $90 on tickets. We can write as
5x + 9y = 90
to find x we divide both side by 5
x = (90-9y)/5 => 90/5 - 9y/5
x = 18 - 9y/5
The domain of the relationship is the possible set of values of x and y that satisfies the equation. The domain of this relationship is
0 ≤ x ≤ 18
At x = 0, it means only adult tickets were purchased.
At x = 18, it means only youth tickets were purchased.
